I’ve been lurking on these forums for a while now and I have found a ton of great information, so thanks to everyone that contributes to this site. So now on to my question.
My goal is to produce CBD isolate. For the process I am envisioning, I plan to extract hemp biomass via ethanolic extraction, winterize, then rotovap to remove ethanol, then distill for the cannabinoid fraction. At this point, I assume the distillate will have [THC] over 0.3%. From this point, I plan on recrystallizing in pentane, then mill/crush the crystals and dry.
What I am wondering is if I can get away with skipping distillation and just rotovap the ethanol away and go straight to dissolving my oil in pentane and then proceed with the crystallization. Assuming my crude is >60% CBD and <5% THC, would I still be able to crystallize CBD? What are the downsides to this and is distillation (or even chromatography) of some sort a requirement to produce isolate?
Thanks again to everyone that contributes to this great resource and I look forward to your responses.
