About 8 years ago i read this article or theory or whatever, and it talked about how each substance/neurotransmitter influenced the evolution of human beings aswell as formed a new layer of their brain.

For example, it said that the base layer of the brain correlated with opiates and was like being in the womb and compared it to comfort and the very inner layer of the brain.
Then the next layer was alcohol and GABA saying that it formed the part of our brain that was used for socializing and stuff like that
Then the next layer was for dopamine and amphetamines and stuff like that used for creating and building things.
And it went on from there. I've looked everywhere to find this publication just so i could reread it because it popped into my head. I consider myself a pretty good googler but after hours of searching i couldn't find it for the life of me.

If anyone else remembers this publication, could they point me in the right direction?

Thanks

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?

pic related the 25 grams of para-hydroxy-cinnamic acid

wouldnt the carboxyl chloride then attack the phenolic functionality on the HO-cinnamic acid?
i reckon extremely low concentrations of the acylation agent compared to the substrate eg morphinnnnee would reduce the ammount of polymerizedd bullshit.

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.

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.

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?

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.

>4.) the residual DMF/DCM is then removed by vaccume and the seed powder loaded back into the column and filled with chilled MeOH and allowed to stand for 2hr before
draining. this is repeated 4 times and the methanol extracts combined, filtered and reduced under vaccume to a small volume. cold ether is added to the methanol solution
untill cloudiness does not dispell and is placed in a very cold fridge for the crystals to set overnight. save this solution. this should afford 6-10g mixed LAA's as the tartarate salt.

ok the seed powder is wet with DMF/DCM, so we want to get rid of that before extracting with methanol; when that's done, we extract the powder four times with cold methanol, combine extracts, reduce "to a small volume" and add diethyl ether to precipitate LSA crystals.

tbh i'm not sure what happens to the DMF/DCM filtrate, i can only assume he just wants to recover his solvents. DMF/DCM is probably a 1:1 mixture. note recovery is 0.1% of seed weight so if you only have 10g of seeds you're gonna get back about 10mg of LSA which is a few (active) doses but also a very very small amount of chemical, practically impossible to work with if we're being honest

2 forces, force of gravity Fg down and air resistance Fair up combine to form Fnet. Newton's 3 Laws says Fnet = mass * acceleration which is given as a=2m/s^2. So Fnet = 1.0kg * 2.0m/s^2 = 2.0 N. Force of gravity is Fg = mass * g where g is 9.8m/s^2 so Fg = 1.0kg * 9.8m/s^2 = 9.8N. Fg - Fair = Fnet so Fair = Fg - Fnet = 9.8N - 2.0N = 7.8N.

sup /chem/

I have a small elements collection and I needed to know about the storage of a small amount of mercury...

I have (attached) glass vial bought from Hobby Lobby for like 2$. I am wondering if it would hold a small amount of mercury. We're talking 5mL maximum, probably less (may fill up an inch of the bottom of the vial). The top glass cork will be wrapped with a few layers of parafilm from my lab. It will be on a sort of "display" shelf, not behind any glass but out of reach to be knocked over. I am more worried about the vapors that could possibly form over time than any spillage.

Any input would be appreciated,
Thanks

and seal the ends using a propane torch. look up "ampoule sealing"

That way you can still play around with the mercury in a fun size. When not in use, wrap the test tube in a piece of aluminum foil coated bubble wrap insert. If the mercury escapes, it'll go right into the aluminum which will make it less hazardous as it's a mercury capture mechanism. For spills, use powdered sulfur. You can buy that on ebay in like 100g quantities.

Thank you for the replies. I ordered myself some of the shown test tubes and am not sure how long they will take to arrive to me. I currently have a very small amount (barley covering the bottom) held in the glassware shown, with several layers of parafilm and it is being kept outside. I believe this should sufficiently hold until I am able to make ampules.
