What makes atoms do what they do? by Matilda Hassleway - Sat, 10 Mar 2018 11:49:56 EST ID:PTghO7Nx No.79012 Ignore Report Reply Quick Reply

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?

I'll try to explain a bit more of the historical/experimental basis. Here's just a list of what was known In the late 19th century/early 20th century.

Electricity and magnetism were very well-understood. Maxwell's Equations perfectly described the phenomenon.

Electrons were known to exist, and be somehow part of atoms (although what atoms looked like was a mystery). The mass of an electron was also known https://www.nyu.edu/classes/tuckerman/adv.chem/lectures/lecture_3/node1.html

Light was understood to be a wave described by some solutions to Maxwell's equations. The wave nature of light was obvious, and easy to demonstrate. Just think of light going through a pinhole. However, there was a problem: Waves need a medium to travel through. Sound waves go through air, ocean waves through water, etc. What did light go through? At the time, physicists called the hypothetical medium "the ether". Attempts to study "the ether" failed ( https://simple.wikipedia.org/wiki/Michelson%E2%80%93Morley_experiment ).

Blackbody radiation was also a known phenomenon. You know blackbody radiation. It's the reason hot things give off heat, very hot things glow red, then blue, then white, etc. That's blackbody radiation. These experiments revealed something else that didn't quite jive with the wave theory of light. The classical theory of light predicted far more UV/high energy radiation than experiments showed. It was more accurate to assume light is emitted in 'packets'. https://en.wikipedia.org/wiki/Ultraviolet_catastrophe

Also around this time, neon/halogen lights were invented. When a halogen light is shined through a prism, the spectrum looks very different than what they were expecting. Instead of a smooth continuous spectrum, they saw very small lines.

That was the state of physics, which set the stage for quantum mechanics, and wave-particle duality. I'll write more later.

OK so /chem/ i purchased some drugs online but instead they sent me 98% para-hydroxy-cinnamic acid. what id like to know is can i use this despite only being 98% could i use this in the same way as people use acetic anhydride to add acetyl groups to open hydroxy positions specifically in opis at the 3,6,or 14 hydroxy positions? if not is it useful for really anything?

Basic 1st year equilibrium reaction laws apply.

You have to make it into an anhydrous with SOCl. This is going to be like acetylation with Acetic Acid. It can't work because it'll generate AcOH before it makes Ac-Morph. that's why you have to make Acetic Anhydride first before doing any acetylation.

Does anyone know of any good documentaries about how different drugs effect the brain? Not scare factor "durgs r bad", I'm looking for something about the chemical reactions in an unbiased setting. Something that gets deep into, from ingestion to end of effect, how it metabolises, stores in the body, what endorphins and neurotransmitters things release and what effect that has.

It's a shot in the dark, but drug neurochemistry is an odd hobby/interest of mine and I figure this might be one of the most niche forums that I could ask.

I took a class on medicinal chemistry at the end of my chem degree. It was basically drug design. It covered most of what you're asking about, although it wasn't just about the brain. I don't know if you'll find that kind of thing in documentary form.

For the last day of class he told us to tell him what we wanted to know about, and he would make a lecture on it. I asked about the brain, just anything about drug design and the brain. He just laughed and said the brain is so god damn complicated that there's no way we could do anything in one lecture, let alone one class or several classes.

Everytime. Every fucking time I try and synthesize GBL using the Sandmeyer reaction, the temperature skyrockets up to 40c and a bunch of foam forms atop the post reaction mix. I've used many different brands of HCl, GABA, and Sodium Nitrite. I've even begun to use a mini freezer to perform the reaction. And yet everytime the temperature goes up to 40 - 50 degrees Celsius. What in the hell am I doing wrong? I am following all of the instructions, but it's impossible to keep the reaction below 2 degrees C, and to stop the foam from developing, even with a goddamn mini freezer. The rate at which I add the HCl does not seem to matter. The amount of stirring doesn't seem to make a difference either. Could anybody help a complete amateur out?

heres an idea. instead of using that reaction why not do an easier synth? i just found a gbl synth thats one step and two ingredients.

Go buy some THF (tetrahydrofuran) a pretty common solvent. then use a strong oxidizer like what i read says to use aqueous sodium bromate but idk if theres anything actual special about that oxidizer or if pretty much any equally strong oxidizer would work. the THF then forms GBL in a one step one pot reaction.

You won't have the knowledge base or resources to synth LSD if this is a start from scratch learn as you (I can't say I've ever looked at this other than from a hypothetical POV).

Fester's Book is riddled with misinfo, dangerous, and outdated but if that lost you I don't know where to point. Also, the name is Shulgin not Schulgin


Look up the Leuckart Route or other reductive aminations (aluminum foil method), to my knowledge, these are common ways clandestine individuals produce racemic MDMA, assuming you locate some PMK.

Like someone else stated this is like saying I want to build a nuclear reactor but have no knowledge in engineering or nuclear physics. Also I'm broke and have no capital.

All in all, would it not be cheaper/easier and a better risk/reward to take advantage of arbitrage in your local market through use of dark places?

industrial chemistry will teach you that method is only valid up to 5g on a lab scale and impractical for real life

wokest brain organic chemistry will tell you that since cannabinol has no enantiomers, you can do a very, very easy full synthesis from industrial chemicals like we do with 90% of all the drugs we have. if you want CBN on a large scale, total synthesis is probably the way to go (unlike with THC that has multiple chiral centers)

Sup /chem/,

I'm taking general physics 2 this semester and I have the same professor I had for physics 1. Now it's just algebra-based, and I've been through calculus, so I was able to breeze through Newtonian mechanics and all that. However this semester is about electromagnetism, circuits, and optics. All topics I have zero exposure to. Now the professor is new to teaching at the college level, his experience is teaching middle-schoolers. He is very (obliviously) condescending and talks to his class of adults like they are 12. He constantly makes sexist or racist jokes (but on the fence enough to not get in trouble) and is always ranting about his personal life or past experiences. When he finally does an actual problem on the board he always struggles with basic spelling and arithmetic, and often fundamentally misunderstands the physics concept he is trying to teach. Several times last semester I had to quietly approach him after class and explain how everything he lectured that day was flawed and the next lecture he would try to fix his fuckup but he ended up just giving everyone lots of freebies on the exams.

My concern is that in this new semester of material I will not get a good exposure or foundation in these topics and might be lost in future courses. Especially electricity and circuits, I really want to learn more about that. I am worried he will teach me some fundamental concepts backward or something. Other than pre-reading the text before class what would you guys recommend to get through this course when the professor is a complete idiot and in my opinion not qualified?

Why would you ever do that? Calculus based physics isn't any harder and you just shot yourself in the foot for future course selection.

>My concern is that in this new semester of material I will not get a good exposure or foundation in these topics and might be lost in future courses

What future courses require algebra-based physics as a prerequisite? No physics or chemistry or engineering course would normally accept it as a substitution.

>what would you guys recommend to get through this course when the professor is a complete idiot and in my opinion not qualified?

Have you tried switching into the calculus-based physics 2 course? That would seem to be like the best course of action; you'll get a different (and better) professor and a stronger foundation in E&M since many of the concepts are only naturally expressible by calculus (in fact, most of vector calculus was invented for E&M).

I would guess that the reason why the professor is so bad is probably because the college see algebra-based physics as a remedial class for weak students outside of STEM to fulfill their technical gen-ed requirements and doesn't want to spend resources on it....

LOL. Where is this. I'm unemployed, and could definitely be a sub there.

I haz a question, /chem/: can I use regular rubbing alcohol for this extraction? I am a brainlet but I would really like to try this without pucking my guts out.

Also do you prefer acids or bases?

isopropanol is quite a bit more polar than diethyl ether. I don't think it would work. You could buy xylenes from a hardware store though.

idk who tf wrote that but it's bad sorry to say. here's a real tested tek:

>(all steps to be done under a red photographic light)

>1.) 8 kg of HBWR seeds are ground to a fine powder with the assistance of dry ice or liquid nitrogen.

[note: cold makes the seeds brittle, good for grinding]

>2.) to the seeds is added a chilled (30*F) acidic methanol (80% MeOH/DH2O) solution of tartaric acid (saturated). the ammount needed is just enough to cover
the powder with 1cm of fluid and is allowed to stand cold for 24 hours in the dark. more acidic methanol may be added as the seed powder absorbes it.

>3.) after 24 hours the methanol is removed by vaccume to compleate dryness. the seeds are then made into a slurry with DMF/DCM and loaded into a large column,
the DMF/DCM is allowed to drain through and more is added until test drops evapurate with no residue. save the DMF/DCM filtate.

tartaric acid and lots of other undesirable crap dissolves in DMF/DCM, but salts, including LSA tartrate, do not. we convert the LSA to a salt and then remove excess tartaric acid and most other soluble components of the seed.
