@Elf Machine. I believe the "most DMT salts are hydrophilic" type knowledge was gleaned from experimentation, mostly by users on forums such as this. I wish there were somewhere to find some collated data on the various forms -- perhaps we should make one here eventually. If I am wrong on this someone please point me toward the data -- DMT has sure been around long enough for it to be out there.
Hygroscopic, not
hydrophilic is the term. And yes, most of the data about the hygroscopic nature of dmt salts is derived by experience/experimentation. I am curious however as to who and how came to find that the fumarate salts are the less hygroscopic ones. Maybe the low solubility of fumaric acid in water
per se has something to do with it, in which case one might be willing to test other not so water-soluble acids if he wishes to find other solid dmt salts. Fatty acids are often like this, e.g. pentanoic acid, hexanoic acid, heptanoic acit and so on. SWIM would like to try with octanoic acid whic he has available when he's got time for experiments.

@Nobody in particular. I am reading the PiHKaL entry on DMT and Shulgin mentions the picrate salt forming needle-like yellow crystals with a melting point of 167 degrees Celsius (freebase is 60-80 methinks from going lore). Unfortunately from the small amount of research I did it appears to be highly unstable and likely to explode. Not so user friendly. I don't actually know how many acids that are usable there are, and how much of a difference there are between them. Surely there are tons of rare acids that haven't been tried? Are they simply theorized to be hydrophilic based on the majority of them being created being so?
Too bad picric acid is uber dangerous. I'd discourage any discussion regarding this subject.

Infundibulum, what would be a better salting procedure and how do we know none of them will make solid DMT salts?
For many organic acids a good method is to dissolve dmt in acetone, then the acid in acetone and drop the acid-dissolved-in-acetone solution in the acetone solution containing dmt. Quickly the dmt salts will form and will precipitate. These are retrieved, washed 1-2 times with cold acetone and left to dry. That is the FASA method for making dmt fumarate and SWIM has used them to also make dmt tartrate, dmt citrate, dmt maleate and dmt malate. Dmt ascorbate is tougher to make since it is not very soluble in acetone, so methanol can be substituted in the above procedure.
For dmt hydrochloride dust add dmt in water, then add hydrochloric acid dropwise till dmt dissolves. Then evaorate water in the oven. The latter will also drive away any excess hydrochloric acid. Same procedure holds for sulfuric acid but then the dmt sulfate salts need to be washed away with acetone or some alcohol to wash away the sulfuric acid.
