I stumbled upon this bunch of labware from this old dude I've been working for. I'm not sure what all the components are. Aside from basic college chemistry and a couple DMT extractions, I'm pretty much a layman in the chemistry field. But I hope to do something with it, or at least know what its all used for. Any of you science types able to help me identify these?

By the way, how much pressure do you think those cheap ebay china round bottom flasks can hold without exploding? I assume that there is a quality difference because of the low price but how much different?
Obviously not asking the specific value but just thinking about vaccuum distillations and maybe (semi)low pressure hydrogenations etc. Do you guys think a joint will pop off before the glass goes boom?
Talking about the stuff you can find from ebay when searching for "chemistry kit" and which is shipped from china or hongkong. Are they just shit? At least they claim its high quality borosilicate glass but...

my old uni scripts from vienna stated the maximum pressure at 1,5 bar.
i have no idea how reliable specific chinese vendors are. there are some that do solid work and then there are a lot of fuckers that just want to let the capitalists bleed. ill try to find a shematic

youll have to use good clamps. and i recommend using a security net or an improvised blast shield, combined with a tub to catch any spills.

depending on much pressure youll want to use, you could also construct a pressure regulator akin to a pneumatic trough, but thats for itty bitty pressures- these fuckers are better for estimating hydrogen uptake anyways if all one can get is a ghetto pressure meter

Thanks for the input guys. It looks like i've got a decent setup for clandestine chemistry, its a shame that I probably wont be able to put it to full use. Would some of this be easy/lucrative to sell on CL or something? I have a second separatory funnel and a stand as well that I didn't picture.

I got all this stuff for free, it was just sitting in this guys attic collecting dust and rat shit. If i don't sell it, I'll likely incorporate it into a mixed media art piece, or maybe make molds of some parts and cast copies in ceramic.

You're probably joking, but this is actually somewhat feasible. Decomposing shit releases methane which is flammable. If you can capture it you can burn it for energy. However, methane isn't particularly well behaved, so it may not be all that feasible to get a internal combustion engine running well on it. You can probably get one running, but you're going to have leakage and damage to the seals because they were meant for a liquid not a very volitile gas.

I'd recommend burning the methane to produce heat, and boiling water with that heat, then forcing the steam from the boilers to go through a turbine.

Yes you can. The sulfonyl group makes the H more acidic and thus easier to deprotonate. It also locks the nitrogen lone pair avoiding overalkylation.

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!

Didn't you start your comment by saying that "you cannot remove the cyclopropylmethyl group of the amine" and then go on and say how to remove that group? Correct me if I misunderstand, please.

If I understand correctly, I don't see why it would. The less sterically-hindered ethylene-amino bridge be cleaved vs the cyclo-propyl (more hindered) group?

However, I guess using a sterically selective agent like dodecanethiol would help. You're right that the alkyl group would fall apart but which one? Isee the ethylene bridge snapping apart before the methylcyclopropyl group is even touched with an equilibrium of 1:1000 or greater

OP was talking about naltrexone, which contains the methylcyclopropane substituent, the guy above you is talking about naloxone, which shares the same structure as naltrexone except with an allyl group instead of a methylcyclopropane group forming the substituent.

See picture for reference.

A. muscaria - complete decarboxylation of ibotenic acid to muscimol by Faggy Sorringdedge - Thu, 17 Mar 2016 12:28:40 EST ID:ge3zUrSE No.77751 Ignore Report Reply Quick Reply

I have a chemistry related question for you.

I've read in two separate sources that it is possible to decompose all the ibotenic acid in the muscarias to muscimol by boiling it in a very low pH solution (2.7). One source seems to have used HCl to achieve this. I was wondering if this would be possible to achieve using household vinegar or citric acid.

5% household vinegar seems to have a pH of 2.4, but acetic acid has a low vapour pressure, so boiling vinegar would vapourize acetic acid with water. apart from making your house smell, vapourising acetic acid would drive the pH of the solution higher, so you might need to add more vinegar to the pot regularly.

However, attempting the same with citric acid seems to be more straightforward since citric acid doesn't vapourise as readily. You can just add water to the boiling solution to cover for evaporation losses and be fine. Lemon juice is said to have a pH around 2, and you can calculate the pH of a solution from the amount of citric acid you add so it should work.

After 2.30 - 3 hours of boiling, you can just add some sodium carbonate to neutralize the pH in order to make it more palatable, and filter to remove leftover carbonate/mushroom pieces, and drink. I'm pretty certain this step wouldn't alter the structure of muscimol.

The conversion from ibotenic acid to muscimol seems to be dependent on pH, so I think it should be possible, but I don't have enough chemistry knowledge to say or certain. What do you think?

If this works, this could be used as a very easy homemade tek for preparing Amanitas.

Pic related, ibotenic acid converts to muscimol after boiling at low pH.

Hey guys,

I want to get into chemistry. Can you recommend some good, free online courses or something? Or maybe some book(s) that is good for a self-learner? The site study.com offers a free 5 day trial (afterwards the cheapest thing is $50/month which isn't bad), I will give that one a go. On this other site, alison.com are some free courses of introduction to chemistry, which is exactly what I'm looking for, but it looks like these are only videos, I'd rather have something like videos and presentations/written text so I can re-read it and learn it.. you know, just like in college. Yeah I could make my own notices while watching the videos but fuck that noise, I hate making notices. Any suggestions?

I remember as a kid I used to mix mr muscle containing NaOH, aluminium and water. A strong exothermic reaction occurs by mixing the NaOH and water. Adding the aluminium instantly reacts with the solution and creates hydrogen gas.

gasoline + soft soap or styrofoam. stir in sytrofoam until gasoline will not dissolve any more. Makes napalm.
Ammonia nitrate (Slit open single use ice packs)+ Potassium something (called salt substitute in any grocery store. make sure it's 100% potassium sorbate or potassium sulfate or something). Don't remember the ratios but find that shit out yourself nigga. Crush the ammonia nitrate beads to make powder. Mix the salt substitute in water and boil it until it stops dissolving. filter out whatever remains and discard. Add the ammonia nitrate powder to the water and heat slightly because the mixture will lose temperature quickly. once it is completly dissolved, put it in a mason jar in a fridge overnight. in the morning scrape the crystals. You may get more if you put the liquid back in the fridge.
Crush the crystals into powder. This is potassium nitrate, or "saltpeter".
From a chemichal supply or science or gardening store buy pure powdered sulfur. from a gardening store buy charcoal powder. In fact, your gardening store may stock stump remover which is sometimes pure potassium nitrate, meaning you wouldn;t have to make your own.
75 parts potassium nitrate, 15 parts charcoal powder, 10 parts sulfur makes black powder. 50 parts potassium nitrate 40 parts charcoal 10 parts sulfur makes blasting powder.

stop bein a faggot an just look tis shit up for yourself. The limit for black powder purchase WITHOUT ID and without being registered is 75lb. you can buy enough gunpowder completly within your bounds of a regular citizen to bring down an apartment building. feds ccouldnt give a shit what you do if you're not islamic or mexican
