mate if you seen i did not discuss any method i just talking about purity if you cant get pure product it doesn't mean it can not be,if you read this one pot synthesis they also mentioned pure product means it should be near above 70 % , i didn't mention any purification solution because this...

reduction with Fe and Hcl creepy and not good for large scale use instead Tin(II)chloride it is easier and feasible on both lab and large scale.

ok mate i apologize if i hurt your sentiments but i didnt post any proven method i know this is devil and must be handle with responsibility.

mate i will not recommend to do this stuff if you are not skilled and aware with handling lab stuffs , Gupta's method seems look promising and easy but aldehyde form water molecules when react with amine and that will prevent addition , you need reactor and proper inert environment to perform...

mate you are diverting this conversation in wrong way , first of all i am not dealer i am qualified chemist and did it for purpose and i made it 97-98 % pure and yes it was less pure around 60-70 % in synthesis but after purification once or twice we had 98 % pure i attached hplc report with...

well you can use it with small trace although it is solvent and not interfere much in reaction but may be affect little on yields

what matters in this report is already there who cares what dated it was and yes it is a piece of shit for those who can not understand HPLC report i can understand their pain in the ass ,so please people keep ice pad near you

chill mate its not for you .

this is we got after some try ...

you really want to try this synthesis.

it create inert atmosphere and prevent some side reactions you probably get pure product and high yields

i tried with it 4-5 times so i lost total 20 gm.

can we smoke sulfate salt ..? i tried and sulfate salt is very easy to make just add H2SO4 10% and Acetone mixture and filter precipitate, wash with acetone to purify it...

then what we get

you can use acetyl chloride, propionic anhydride or acetic anhydride also.

i want to raise this devil if any one can arrange voodoo stuffs ....

can we do this amphi to meth process before converting it into sulfate during amphetamine synthesis ....?
