and what do you think about adding AcoH after the reaction is finished? in some recipes they write about adding ... Don’t know, haven’t read about it.

I have extracted numerous times with petroleum ether but maybe I’m dumb..

I’m not sure what you mean but you should extract the water phase a couple of times with a non polar solvent like toluene,petroleum ether

I can’t speak for the synthesis of amines, but the main driver of yield, if adequate catalyst is present,a primary amine that you know 100% catalyzez the reaction(the 2 listed by you) is removal of water. Simply put the reaction is reversible and the more water you take out of the system the...

I wonder if one day i’ll do enough drugs to reply as if I’ve not even read of a word of what is being said to me and brag about having 200g of a commercial dietary supplement like I had 2,5-dimetoxibenzaldehyde

No, I just heard second hand you get monster yields compared to the dose, i have no knowledge or experience here

Benzodiazepines I’ve heard are cheap per dose.You synthesize thousands of doses in 1 run.But then dosing and pressing pills is the bottleneck.

I heard from patton here that you should heat it up before.Something I’ve never done with sulphuric, but then again my acid is pretty pure. Order from poland if you’re in the EU, they will sell you barrels of literally anything lol

I don’t know, I’ve only had it happen once, then I made sure i didnt have too big of a layer and that one time i didnt try to recouperate.Also phosphoric acid is trickier to get working than sulphuric.I recommend you find some of the latter.

If you’re thinking of distilling I know for sure you need vaccum, maybe even inert atmosphere.It starts breaking down in the presence of air earlier than it’s boiling point as far as i can understand.Steam distill is what people go for commonly I think.

No need to evaporate at all if your organic layer is concentrated enough with product.If the freebase is too dilute it’s gonna precipitate like crap or not at all.I aim for 100ish ml organic layer first wash from 5g of propene.Then 1-2 more washes with 30-50 ml.

Also, can solvent be recovered here?

Can anyone identify any major hazards in the bromoetan route? I’m aware of the toxicity of both EtBr and NaNO2.If done outside with proper PPE and lab etiquete is there anything else I need to be aware of?

I think it looks a bit sussy, did you precipitate, freeze and filter? Or just precipitation and filtration? Looks a bit like you have left over propene in there because of the wierd crystalization, slightly yellow color.Does your product fully dissolve in water? Was your extract after...

2.Use foil, granules is too reactive.With foil put in coffee grinder or form by hand loose balls.Thin squares are too reactive, it will foam and potentially escape the flask or release vapors. 3.You can leave it too long aswell as too short.The better case is too long but ideally you wanna use...

If I were to guess it’s for the CRAP(Crude reagent and product) to have a place to go to that’s not your organic layer.

Freebase smells acrid and “fishy”, it’s not that big of a strech to assume some of it gets trapped around the sulphate, but idk i might be wrong.

I’m not saying good or bad, there’s a danish study that analyzed adulterants and fillers, I can dig it up.

Active ingredients meth, caffeine.Fillers used are water soluble sugars such as lactose.
