This is what I’ve always used as the BP of thc at atmosphere
Mechoulam says thc boils at 158 at 50 microns, that would make thcs boiling point 430 at atmosphere according to sigmas nomograph
Also, there’s a difference between evaporating and boiling
Boiling happens at the bottom of the liquid usually which is why the stir bar is so huge on an spd
Top is 50 microns (154.6 BP on thc if it boils at 425 atmosphere)
Bottom is 10 microns (138.5 BP on thc if it boils at 425 atmosphere)
