If I set up for a reflux but never let the naphtha get real hot think I could just vaporize the dmt  and collect it in my condenser? This may save a freeze precipitation. If it recrystallizes I may be able to just knock the crystal out of the condenser with a stiff wire or something. If not I could always wash the dmt out with minimal solvent, say heptane to freeze precipitate. what do you think?
