Quote from: matosago on January 04, 2013, 06:02 amAccording to the DEA meth melts some twenty degrees C below Isopropylbenzylamine... 170C vs. 190C.Besides taking advantage of that you could do some chemistry, but being structural isomers it is not going to be something you can probably do on your own without a working knowledge of organic chemistry.If you want to do some reading I would suggest googling the separation of amine structural isomers. The key to the reaction should be the difference in distance and dipole caused by the difference in location of the amine in these two compounds. Interesting. Thank you very much, sir: you seem to have given me enough of a clue to hunt down the information myself, and that's good enough for me. Cheers :)
