Why should the boiling point matter? Flash point is another thing entirely...
Because of science. Don't worry, the scientists know what they're doing.
I also meant FP being freezing point.
Whats a freezing point?
Its called a melting point.
Obviously the same thing but FP isn't very descriptive.. use mp and 'scientists' will know what you mean.
FP is universally known as the flash point.
Don't be condescending towards others because you can Wikipedia things and call it science.
Besides, even with the high melting point of DMSO, its not that high. It's below room temperature, its certainly a suitable solvent for vapour diffusion. With a high bp, and powerful solvent capabilities for small molecules like this, it isn't just suitable, its choice.
But, I can't help but wonder why? What is the point of this? This is possibly a good method for growing sexy x-tals but, for precipitation? Really? Reminds me of a student who used to work with me in the lab who would always try his best to over complicate every process. He would want to use a mixture of solvents when ether alone worked just fine, etc...
You want to precipitate DMT at room temperature? Why not just crash it? That is basic first approach to precipitate a compound for an organic chemist. If that doesn't work, then you move onto the more labor intensive processes. Downwardsfromzero suggested adding concentrated DMT solution in acetone to water, the acetone would be massively diluted into the water and cause the freebase DMT to precipitate instantly. Especially, and to completion, if the water was basic.
Crashing out fumarate salts in nonpolar solvent, and then crashing out the freebase in basic water, this is quite familiar isnt it...
