i can only get 50% acetic acid locally, can i use this? if so, what changes would i make ( heat method ). I know acetic acid can be a pain to get fully concentrated, is there a way to push it up to 80%? Or can another acid be used? Also are there any risks i should know about? (explosive/toxic...

Here was what i did on a smaller scale; 1. Solution IPA/H2O 2:1 ((IPA 800ml,H2O 400ml)(1200ml)) was added a 2000ml flask. 2. NaBH4 (116 g) was added at once and stirring was started. 3. P2NP (67 g) was added in small portions, so that the temperature of the mixture did not exceed 60 *С. 4. CuCl2...

i have now reached 60%

The P2NP was dark brown , i did 2 ipa recrystalisations and got clear ish crystals with a brown tint, i think it was as good as i could get it without wasting too much time, but now i have some product i will keep washing until IPA is clear. I think next time i will make it myself and store it...

I will write up what i did differently tomorrow.

i filtered the precipitate after basifying. Ive had alot more precipitate , acetone used to wash was placed into the orginal alcohol acetone mix and placed back into freezer. My yeilds looking like 50+% at the moment and hopefully more comes after a night in freezer. I tried 25mg of it and it is...

I yielded 40% white (ever so slight grey tint), bone dry phosphate salt. This was from my brown P2NP and i def lost some freebase to not knowing the main extraction was in the top layer. I am very happy for a first synth, despite yield being low. With more cleaning of P2NP and if i implement...

thanks for that. yeah i was meaning the water in the acid and solvents rather than water alone, i didnt dry anything. I just checked the freezer and i have a thick layer of precipitate at the bottom which is great to see. In the future ill aim for higher yields by following drying methods etc...

should the ipa + freebase mix be cool when i acidify? should the acetone be chilled beforehand? or does it not really mater if its going in the freezer for 12+ hours?

if i add too much water, can i raise the ph back up to 11/12 to turn it back into freebase? and then separate & dry the solvent?

okay thank you. my country is risky compared to eu so id rather process a dead battery i have. which is fine, i just cbf at the moment and want to get this underway.

okay all good cheers. I have a battery sitting there too process, but i dont have time this run. i cannot buy sulphuric , but i can buy phosphoric ,so i have some. do you know what differences phosphoric may need?

okay thank you. and what would i do if there is too much solvent @ ph 6 and it doesnt precipitate? would it precipitate as it evaporates?

what is the boiling point of amphetamine freebase?

awesome, thought something was up so i saved both phases i will sort out the solution later. Do i have to completely evaporate off the ipa from the freebase or can i just bring it down to a workable level? ie 10%?

that is what i am talking about. is amp freebase+ipa on top layer after basifying?

hold on is the organic phase after basifiying loaded with product? is it just the IPA from step 1?

orthophosphoric acid yeilds amphetamine phosphate, which i what i was going for.

could you explain further the hcl and nitrate method for dissolving mercury? what weight of mercury metal for this size? i have small thermometers
