About this process:
CBD can be converted into delta-9-THC with anhydrous ZnCl2 at 150° without solvent (perform reaction best in vacuum as product is sensitive to oxidation):
Heat 0.5g CBD with 0.09g anhydrous ZnCl2 under vacuum with stirring.
After 2 hours 40 to 50% delta-9-THC have formed.
They are in its beginning two solids in powder form…
I understand that at 150 degrees cbd is in a liquid form… so stirring makes more sense?
What tools or materials would you use for make the vacuum?
How important this is?
In the other side, cbd start to evaporate at 160…
So would you use a reflux column for preventing evaporation and let the temperature oscillate a bit or in other case, how would you keep it at constant 150?
It says that after 2 hours 40% has been converted into d9 thc, if we let it longer, lets say 12 hours will the 100% been converted?
May be doing the 5% KOH in ethanol cbd test from time to time until giving negative result?
And finally, how would you separate both substances with out SPD?
