Want to make qwiso or the like but dont have adequate facilities to boil off. Is it possible for me to do a rinse with iso and just let it sit until everything evaporates off? Thanks for any input
Evaporation works ok for the first part, but once it gets a little thick, it becomes difficult for the solvent to get to the surface to evaporate. Peace GS
So lets explain. Butane evaps at 30F, so technically you could make BHO that doesn't need to be boiled.
In all of my reclaim experiments with ISO/Everclear it fully evapped out on it's own... I don't know why I hear people saying to heat up iso..... Sounds like a horrible idea to me. You would know if there was iso left in your solution(your lungs would be on fire). Iso isn't super sticky like BHO either.
I have seen many bho's that are not properly purged. If the solvent in in the middle of the oil, where does it evaporate too? Seems like it could not escape. Peace GS
