Complete amphetamine freebase (A-oil) synthesis from P2P(10L scale)

[Davidrobinson]

And theres nothing wrong with the amount of acid for hydrolsis . Have you done this synthesis before tweaker?

oscar412nothing wrong with hydrolysis?Yes there is almost everything.yes i have done this synthesis with my friend long time ago.

 

[Tweaker]

yields were not very good anywhere from 700-800 grams dry amphetamine from 1 litre p2p if i remember correctly,we never calculated the oil we just salted it after distillation

tweaker2Sounds like gold yields to me. Do you use a catalyst in your lecukarts?

 

[marapiasss]

Is there any way to know if the A-oil is diluted in something? or its purity?

marapiasssTLC, thin layer chromatography. It is not difficult if one just wants to check for the presence of other compounds, qualitativ. Doing it in a way which allows quantitative estimations (how much of different compounds is there) is demanding though.

 

[marapiasss]

and what about the ph, what should be optimal for the amphetamine base?

marapiasssIf it's totally water free 10 is ok if it has water, that normally has if you buy it to someone, ph should be around 12-13.
When it's water free the PH increase when you mix it with solvent.

what's the density g/cm3 of the amphetamine freebase?

.936 g/cm3 at 25 °C

Hi

what type of equipment can you recommend/ use when distilling the oil?

tthanks

SwesweDepends on amount to distill, type of distill you need, product...

btcboss2022Around 10L , fastest and best way

Thanks

 

[btcboss2022]

btcboss2022The fastest way is with a steamer, similar to this equipment:

Steam is "injected" with pressure from an external water boiler and the mixture distilled in the main tank..
For 10L you can do it with 2 big flasks, one to boil water and generate the steam and the other to heat the mixture, receive the steam from the boiler and distill the mixture.

btcboss2022Alright thanks, Will try with 2 bigger flask to start with

btcboss2022What do I need to watch out for when purchasing stainless steal equipment for chemical use?
Also, does someone has a link for a 'Steamer' that was already tested and used by a forum member for our purposes?

KokosDreamsNot stainless steal! Never do that, must be s316 the mixture is totally alkali.

btcboss2022Thanks dude! Now, that you're here! Let's connect via dm real quick

Double message sorry

good afternoon ! I really like this synthesis, I've made it several times. but the yield when I need to get nform will be small at that point. I get 5L of nform from 10L of dirty P2P, and 1.5L from the aqueous layer. so in the end, after steam distillation, instead of 8.5 L yield, I always get 3-4 L. I do not clean the oil during any procedure. I think the steam will clean it. please anyone who can advise, thank you very much

tucoxXx1N-Formylamphetamine Hydrolysis by NaOH way
1. Put the 11L of N-Formylamphetamine in the reactor, add 13L previous cold 65% NaOH solution slow stirring with reflux during 2-3 hours at 110C.
2. Stop heating and cool it at RT

use here methanol + less water and NaOH or KOH (for me KOH better), with methanol go to 85-90C.
you will see much difference

ossiCould you explain please the proper ratios for methanol + lye solution + n-formyl derivate?
Why go only to 85-90C? And why to add methanol?
Do you mean it will be difference in yield or where will be the difference?
As I only tried normal Naoh hydro

Researcherrfor 1 liter n-formyl mix1,2-1,5 liter methanol, 700-850 gr KOH and 0,3-0,6 liter water. dissolve KOH complete. After it has cooled down a bit, put it in the fridge for a few hours. put this mix under stirring to the n-formyl and let mix half hour without heat. after go to 85-90C.
85-90 bacause boiling point from methanol is lower than water..
it will much more yield, i never would cook without methanol
and finally steam distillation is a must! (low temperature, more yield)
and you will get more yield , if you you use p2p formamid and little more formic acid.
if you have more formic acid you can cook at 140-145, this gives more yield.

 

[tucoxXx1]

I realized I did it wrong p2p-> nform . I didn't let it go for 5 hours at 150 degrees. after the temperature rises to 150 degrees (for me it takes about ~4 hours. when it reaches 150 degrees, it has to be kept there for 6 hours and I got 8L of nform, 10L of P2P. I take 2L of nform from a watery reteg. I use a 10% baking soda solution for washing, it works perfectly )) )))) you say that when the naoh hydrosis is ready, it cools down, should I add methanol? what kind of gold? should I boil it again at 90 degrees, for how long? do i need to see something when i'm done?
