I was looking up how to extract DMT and apparently it's most commonly done with Mimosa Hostilis root bark. Looking at the guides it's very MacGyver tier. I'm saying I'm wondering if there is a more professional way of doing it. Essentially I'm asking, if you ever looked into extracting DMT and if you have the chemistry background, what methods of extraction do you prefer/recommend and do you have any advice regarding it? Perhaps a mistake that commonly diminishes the quality of the extraction or some deviation from the existing guides to end up with something more pure.

Rotovaps make chemistry much, much, much easier. That's a device that evaporates solvents very quickly.

Solvent choice is also very helpful. The amateur has to choose between a few commonly available solvents meant for shit like paint-stripping. Professionals can choose a solvent that has analytical standards, and is harder to obtain (can't get at the hardware store).

Pros also have better filtration systems. This is less expensive than the rotovap, and not as much as a time save, but still very helpful.

TLC plates help keep track of whether or not product is there (so you can be more efficient when pulling).

Better ventilation is nice.

Lab freezers are better than home freezers, and usually have safeguards to prevent blowing up.

In the end, if you have white crystals, it's a reasonably pure product. Crystallization is cool like that. However, a well-stocked lab will get higher yields in less time.

When doing TLC I am separating by molecular weight, no? If so, how do I predict how many bands I should get during these sorts of processes?
Sry if these are silly questions. I am a physicist only familiar with a bit of chem, mostly spectroscopy.

TLC is most often distribution chromatography ( with a smidgeon of absorption chromatography) , meaning its more about polarity of the substances than about their weight itself (though there often is an indirect relation between weight to affinity). you basically have a solvation hull on your substrate and the mobile phase flows above that, depending on the polarity of a substance it moves between the stationary and the mobile phase, thus seperating from other substances. ive made a nice animation for that shit but im too paranoid, ill see if i find a comparable animation

in theory you should get one band per compound of your mixture but high concentrations or an unsuitable eluent may lead to streaking and improper seperation depending on the number of theoretical seperation stages.

in the OP scenario TLC would only serve as an analytic tool, even column chromatography couldnt really yield a lot of DMT doses

youd be seperating by molecular weight if the different compounds had no intrinsic dipoles. i used to hate chromatography since its such a bitch ass compromising bullshit way of seperation... wait theyre all based on equilibrium

I started a thread on /spooky/ asking for any evidence of the paranormal or supernatural.

Instead all I got was a bunch of personal attack and people babbling nonsense and presenting it as truth. Then when shown they are incorrect with verifiable data rather than pseudoscience they resort to personal attacks again. They and pretty much all other magical thinkers take any sort of challenge to their beliefs as a personal attack.

I was at a party a few months back and some girl was talking about how she went to some yoga guy who does "laying on of hands". Which involves doing yoga while a dude puts his hands on your body and makes weird noises. Supposedly doing this achieves any number of effects from healing wounds, curing depression and other supposed boons.
not arguing the therapeutic effects of yoga just the laying on of hands part
I tried to understand what she was explaining to me by asking questions. Like asking her what was actually happening because it made 0 sense to me. Instead she started insulting me for being closed minded and shit.

Also in real life I live in the US south. Where people who think the world is 6000 years old is the norm.

Needless to say I deal with people who use magical thinking on a regular basis.
They are 100% willing to reap the benefits of science and the technology that comes with it until it conflicts with some myth or story about ghosts or some shit some one told them. Then all reason and logic go out the window.

Why do so many people especially in the us reject verifiable facts over what feels good? I went to the same public schools as them, I was also raised in a religious household (jewish, although I'm no longer religious). The only difference is that I chose the rational answer.

I agree, I just tend to shy away from the word. What happens all the time is the scientific community accepts something in a consensus, only to have that consensus overturned or it falls to more complete models. As you said, just try to keep a healthy dose of skepticism of everything since we are so far away from total understanding of anything, especially in the realm of physiology.

She was probably just saying that because she wanted you to be sceptical and then invite her to demonstrate or whatever out of "curiosity" and it would all quickly escalate into sex.

Didn't read the thread so don't know if anyone has already mentioned this, but you should look into something called 'English Prime.'

Basically it takes the concept of the Sapir-Whorf hypothesis (that language creates mental state, that ideas possible to be expressed within a language are the borders of the space in which speakers of that language can have ideas at all) and uses it to attempt to fix English by making it more explicitly scientific.

For example, it removes almost all constructions of 'to be' including 'is' and 'are.' Nothing is good, or bad, or blue, or fast, but can seem, or appear, or correlate to those properties. It basically forces people to remove the unscientific and unprovable but completely common habit of claiming things 'are' things, reducing it to the simple truth; that they seem to be things, and deliberately denying the power to speculate beyond to 'the thing in itself.'


Naltrexone -> Oxymorphone? by Hamilton Beggleshit - Thu, 17 Mar 2016 18:16:02 EST ID:GksK9UMc No.77752 Ignore Report Reply Quick Reply

Dear /chem/,

wikipedia cites that "Naltrexone can be described as a substituted oxymorphone – here the tertiary amine methyl-substituent is replaced with methylcyclopropane. Naltrexone is the N-cyclopropylmethyl derivative of oxymorphone."

Is it possible to revert naltrexone back to oxymorphone? If so, how?

My very limited understanding of organic chemistry leads me to believe that naltrexone could, in proper solution and (probably) with the addition of heat, be broken into oxymorphone and cyclopropylmethylbromide. (pic related)

Any input regarding said (hypothetical) reaction will be greatly appreciated!

Would it be possible to turn the cyclopropane into a terminal alkene using aluminum or something? I know cyclopropane's are very unstable.

And then would it possible to attach a carbon to the terminal alkene? You could attach a phenyl or something and make n-phenylpropyl.

Basically to sum up what I'm saying, instead of trying to remove the cyclopropylmethyl group outright, would it be possible to turn it into a 4 carbon chain, the last C=C being a double bond? And then using the reactivity of said double bond to attach something? You'd be able to make a pretty potent agonist that way.

Cyclopropanes are very unstable but the one pictured with a stabilized alkane group is not. This group shown with an R-cyclopropane is relatively stable.
Carbon-carbon chemistry is very hard. Even harder to do selectively.

the solution is to first replace all of the GHG-producing crap with non-GHG-producing crap, particularly electricity generation (to solar/wind/nuclear generation with hydro/battery storage) and transportation (to battery electric), but also we need to deal with fertilizer, cement, landfills and cows, roughly in that order. only AFTER that is completed we can start fucking with aerosols or satellites or other weird ideas

Humans are the problem, so let's make 'inverse humans' to balance the equation and reach stability.

Humans are a carbon-based machine that chaotically pollutes the environment by consuming oxygen and organic tissue for energy and expels carbon dioxide and bacterial mats(poo.)

Our robot is therefore a silicon-based (silicon is much more abundant on earth than carbon) machine which runs an organized program to clean its environment, consuming carbon dioxide and bacteria to sustain internal bioreactors that exhale oxygen and produce sugar, which then powers the machine. Then we need 7 billion of them.

We're never going to make humans be better or more responsible, it's utterly futile to try to bet on some 'better angels of our nature' solution. We need to design something that, as it seeks it's own natural path of least resistance, naturally counter-weights our own natural path of least resistance.

Well, humans aren't made of bacterial mats, so no, my suggestion was robots that consume human poop for nutrients and breathe human exhale to fix carbon into sucrose. Like all lifeforms, they would only engage in the behaviors they were programmed to do, so if we gave them the instinct to fear and obey humans, they would. However, even if they went out of control and killed off humanity, they would do more for balancing the ecosystem in that than we've ever done. From the standpoint of survival for life on earth, it's a win-win scenario.

I want to reduce 3,4,5-trimethoxy-beta-nitrostyrene to the amine. What will do this? I've found so much worthless and bullshit information. It seems the main options are:

  1. Zn/HCl or Fe/HCl. I don't know if this goes from the nitrostyrene to the amine or if I need to use NaBH4 to first reduce the double bond. Also, some people say the yields are good and others say the yields are shit.

2. LAH. Not an option.

3. SnCl2 to reduce the nitrostyrene to an oxime and then Zn to reduce the oxime to the amine. I've never found proof of anyone doing this reaction on nitrostyrenes. SnCl2 is good for reducing nitropropenes but who knows if that applies to nitrostyrenes.

4. Al/Hg. Literally toxic. I haven't found any reports of people using the less toxic Al/Ga or Al/Cu amalgam. I also get conflicting information saying Al/Hg reduces directly to the amine, yet others are saying NaBH4 must be used to first reduce the double bond and then the Al/Hg reaction can be run to reduce the nitro group to an amine -- which is it?

Any input would be appreciated, especially from people who have actually run these reactions on this particular substrate.

Zn/HCl is the method of choice for terminal nitrostyrenes, but it fails for nitropropenes. Fe/HCl gives carbonyl compounds which you don't want. Make sure your zinc is good.

Sup /chem/,

There is a fundamental gap in my understanding of the universe. When we look out into the sky and see the sun and stars, measure the Earth orbiting the sun, or see a volcano, it is commonly accepted that eventually, all of these processes will run out of energy and cease to do their thing. However every atom in the universe has positive and negative charges, with the negatively charged particles constantly in motion (and i guess the positive ones too if we count vibration or whatever). How do subatomic particles get a charge in the first place? Will it ever wear off? What makes electrons move? Will an electron ever stop moving and become neutrally charged? Can we apply this seemingly infinite source of subatomic energy to the macro scale to prevent a big freeze or one day generate limitless energy?

OK. I'll finally try to follow up. Quickly.

In the last post, I brought us up to the point where physicists saw that light is emitted in packets called 'quanta' at the time. They knew that because of theoretical work following the 'ultraviolet catastrophe'.

But they also knew light acts as a wave, since a single wavelength passing through two slits produces a diffraction pattern (like water waves going through small slits). This is Young's double slit experiement, and was actually an early 19th century experiment (predating most of the experiments I'm talking about here).

They also knew light is a wave because Maxwell's Equations can be used to describe light as an electromagnetic wave very accurately.

But, unlike waves, light didn't appear to travel through any medium. Sound travels through air, ocean waves through water, 'guitar waves' on taught strings, etc. They called the theoretical media that light uses "ether", but attempts to prove its existence failed (the michelson morley experiement).

They also realized that, in many cases, light spectra weren't smooth and continuous. They had very sharp, unexpected lines.

Also at this time, Einstein described the photoelectric effect, where light could be absorbed in quanta

To recap: At this point, the long-held theory that light is a wave was being challenged by a bunch of experiments/models.

And then, while trying to figure that shit out, a bunch of experiments/models suddenly showed that MATTER is a wave.

This is still really only the preamble to quantum mechanics, and it's where the math starts to get more intense. Until this point, the math involved was pretty much calculus and differential equations

The next big experiment would be the one that hippies and armchair philosophers love, which is the variation of the double-slit experiment where observation changes the expected outcome. People try to extrapolate so much metaphysical bullshit with this experiment, and I hate it. Yes, it's an amazing result. yes, the math is deep and profoundly alters how we view reality or truth itself. But at the same time, it's simply a mathematical model that's describing what we see. And then we call it reality. It's boring.

IF I do another post, I'll try to explain this experiment, the math it spawned, and the (legit) philisophical interpretations. This is where linear algebra comes into play, infinite arrays, the schrodinger equation, imaginary numbers, wave equations, and more. IMO, it's the point where "quantum weirdness" becomes solved for the most part. There's some philisophical differences of opinion, but they're not too important.

>A positive charge interacts with a positive charge differently than a negative charge interacts with a negative charge.
Also, fuck. This should be "A positive charge interacts with a positive charge diferferently than a POSTIVE charge interacts with a negative charge".

Of course, P-P interactions are identical to N-N interactions.

Oh yeah, and of course special relativity/gravity is still an open question in regards to quantum-scale. Blefht. I'm done. These rambling posts brought to you by Bush. Breakfast of champions.

Need some help guys. So for ???? reasons I'm making a program that models geological systems and mineral formation. Does anyone know of a good source of information on the crustal prevalence of various minerals? I obviously can't simulate every mineral known to science, but I want to get an appropriate swath.

Much appreshes.

Oh shit, maybe this?

Here's a visualizer: https://www.clisap.de/fileadmin/B-Research/IA/IA5/LITHOMAP/
The general website:https://www.geo.uni-hamburg.de/geologie/forschung/geochemie/glim.html

Still doesn't seem to include the ocean, which seams kinda important. Maybe I'm missing something.

NVM. It's still very general, and not really saying what the minerals are. But when you google for "minerals" you pretty much only get exploitable minerals.

I'll stop posting now.

Wow that's a fuckin cool link you found. Unless there's the same data somewhere in table form it's not very useful to me, but I'll probably be dicking around with it anyway, very interesting stuff.

>> You just want to know the total % of minerals, but not the geographical distribution?
Yes, then once I have percentages enough to single out the most significant minerals and soil types (scientifically significant, rather than economically) I will very crudely model what conditions cause the transformations between the different types (elemental composition, heat, pressure, water content, etc.) in order to spit out a world map that is geophysically earth-like but not the actual world If you must know, it's a map generator for a game

>>you pretty much only get exploitable minerals
Yeah that was my frustration which is why I came here in the first place. All lists are either popular/business ones that only list exploitables, or really minor geological papers that go into great minutae about some mineral that only exists in this one crater in BFE. But just by gumshoeing through that I was able to come up with a reasonable middle between the two. 'Rock-forming minerals' was the keyword that seemed to work best for me.

Anywho, thanks for the help guys. I guess we can keep talking about minerals because they are pretty rad, otherwise I will necrobump this thread if it hasn't fallen off by the time my generator is working and show you guys.

I don't know if you are familiar with Dwarf Fortress, but the guy who programmed it knows a lot about geology and has already done the same thing you are trying to do. Maybe if you ask him he will show you where to look or maybe even help you.

Ah thanks but no, those guys are notoriously tight lipped and the complexity of Dwarf Fortress is far beyond the pale of what is necessary or would even be functional for my purposes. Besides, at this point Dwarf Fortress is well studied within the gamedev community and it's easy to get references about how it works without having to bother those two guys.

Definitely though what I am working on has some broad similarities in terms of making a world simulation that leans on emergent properties, but I'm basing it on real world science and chemistry rather than fantasy. Instead of 'mine 5 generic shits and 5 dire poops to craft 1 epic turd' it will be 'collect 75 kg water, 25 kg bacteria, 5 kg protein and 20 kg sugar to make 100 kg of epic turd'
