I had 250gs of pure 2b4m straight from international. I mixed 500ml of benzene in a 1 litre glas flask. And 350ml of 40% aqueous solution (all good 99.9% lab grade) as I have afriend with pharma license Then I stirrered it periodically for 24 hours. Then I transferred it to a plastic 2 litre bottle flushed it with water properly. And drained it kept the top layer and used 1/10 36% concentrated hcl 150ml 1litre of acetone and used a pipette to transfer it for acidification. Waited as the fumes started to roll.. nothing happened after 2 mins so I rolled up all acetone concentrated hcl mix altogether into it after doing it for 35-40 times. Now 2 layers r formed. One which seems thick is on the bottom and on the top is dark brown cold chilled liquid I feel acetone. I don't know what went wrong I wanted to synthesis 4mmc all the materials used are 100% lab tested and procured from original sources. Now I have left with a 2000ml of liquid brownish dark black. What to do help. ?
