well, you lazy bees arent interested at all in the oxime method...
anyways, I will post my friend´s results, and hope to have someone around with experience
in forming the oxime to make precious MDA.
From the last post, he got back to his lab and opened the freezer only to find
nice crystals in the smaller (2x) entirely and beautifully crystallized!! Not only that!
all his not-washed equipment contained crystals as well! He found this so amazing he
got on drying the dcm from the batch he thought went wrong and got MORE CRYSTALS!!!
He has repeated the 20x procedure 4 times, with good, beautiful reflux and the oxime oiled out
everytime, but in the morning he consistently got nice crystals in his freezer.
Anyone has the same experience?
He put most of his batches in vacuum to dry and will leave there a few days, but he tried to
light-dry one of them and he got SCARED!!! it seemed to melt, but it was definitely not 80C.
He supposes the oxime re-dilluted into the solvent (water) that was still around. does this
sound reasonable?? is there a faster way to dry this baby? (NOTE: he put this batch in vaccum
too and although he didn´t check, it looks like has crystallized again.)
thank you all 4 your time and knowledge
