DMT benzoate is stable in air. I crashed it from limonene pulls.
Dasein also got xtals from naphtha (but naphtha has less margin before excess benzoic acid saturates + it is less powerful pulling DMT).
Unfortunately DMT benzoate is not soluble in PG. Would have been a very easy way to get a very clean vapable product.
However, if acetone is added to toluene (similar to FASI but I'm a different order of ingredients to not have to prepare a separate solution cause I'm lazy), fumaric acid forms and that is soluble in PG. So one more ingredient but this could be a very convenient method. Working on it. Also revisiting ethyl acetate + fumaric after a good chemical dry.
