240% yield of amphetamine.. what's going on!?

[mithyl2]

i recently synthesized 2 batches of amphetamine with far higher yields than what they should be. both have a fairly strong smell to them, and the consistency of the amphetamine once dried immediately after the synthesis is very hard, with a sugar-like texture.

the yield of one batch was 18.16g when it should have been 4.52g at most.

what could be going wrong?


more details:

i did a wash with dry acetone for 9g of this batch to see what difference would be made, but there was only a drop of 0.5g in weight afterwards. (the amphetamine of one of the batches had a yellowish color which disappeared after the acetone wash but the smell, while a bit fainter was still there.)

i still need to do an A/B extraction but even so it seems like something has clearly gone wrong with a yield this much higher than normal.

what's strange is when i tested the amphetamine (or at least what should be amphetamine) with 3 different types of reagent tests, it was positive for amphetamine on all 3. (although the marquis test results were very faint, the color brown still appeared.)
the tests also didn't show any other products being present.

something else which might factor into this problem is that the p2np i used may have been contaminated with sodium bisulfate, because i tried to purify it by using sodium bisulfate (mistakenly in the same amount as the p2np i had), and then doing a recrystalization. to counter this i did maybe 2 more recrystalizations, with the resulting p2np being a light yellow and a faint smell, whereas before it was the opposite.

can anyone confirm if what i have is actually amphetamine?

 

[mithyl2]

also if it's relevant i used phosphoric acid when precipitating the amphetamine

Maybe it got contaminated with sodium bisulfate. Is it hygroscopic? Because then hydrogen oxide (water) can get into it too.

BlueDexi don't think sodium bisulfate is particularly hygroscopic. but i don't know.

have you ever heard of this happening before?

taste the product if it tastes salty then its mostly sodium.did you use naoh to basify?

hobokingyes. i won't be consuming this yet.

After reaction done,distill all sluge,and then,falow acid base,read the forum,all money is here,just read!!!! You reaction not finished,or you did mistake with extraction base,, ,after reaction finish it shut look milky liquid,without any trace of aliuminium,and without any bad smell,you need distill,,after first stage reduction,,answer for you.Then alll reagents messure corectly you have no bad smells,at all.

metuxi'm using sodium borohydride for reducution, so there might be some differences

Years ago I done the A&B in A-oil freezing cold temp only tuck 6 drop and the hole thing swelled up like a mushroom thick white like ice cream
Wasn’t the best product but the job..
