You kinda lost me there when you said that to freeze precip you will need to convert it to a salt..when you freze precip with a np solvent you precip freebase...you convert it to a salt with FASA or FASI..
No. He has xylene mixed with his naptha, hence he won't be able to freeze precip because the xylene will keep it even at sub-zero temperatures. So, to get the DMT back to pure naptha he will have to salt it (add acid solution). The freebase will bond, seperate, then basify again, and extract with naptha. It's the only way to get rid of the xylene since distillation won't work. Bp xylene 138, Bp naptha 100-140.
