Post-Ethanol Extracted Crude to Crystallization - Crystals Without Distillation?

Hello! 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 recrystalli…

From Crude to CBD Isolate

So, as I have mentioned before, I’m in a non-legal state…but hemp legislation just passed. Yay. I’m interested in EtOH extraction, to be followed by cold-temperature EtOH winterization. We’ll call this semi-refined crude. Now, what are my next steps to get to pure CBD crystal isolate? Do I remove all solvent and then short path? What do I do between crude extract and CBD crystal? Is it near-identical to THC-A crystal mining or is there another component that I’m totally missing? Help, addit…

CBD Crystallization

I would like to get a discussion going on the topic of CBD crystallization: both wanted and unwanted. We often want to force, accelerate, and optimize crystal formation, but what about the flip-side of the coin being unwanted crystallization within an extract intended for use in a cartridge or device of sorts? CBD isolation is much easier, often happening without any encouragement at all. That being said, has anyone had or heard of a successful formulation with a high (>60%) CBD potency and lo…

Seperating THC from our CBD distillate

in the past we have made all of our own products so we could dilute THC down below .3% on our own based on what product is being made. With bulk CBD distillate production and distribution means we want the highest possible CBD with >.3% THC. what are my options? is it essentially only column chromatography? Is there a roof on the THC content in the hemp biomass we are getting to prevent high THC? Just using common sense, with high to mid 90% distillate is going to bring with it concentrated THC…

Future THC/CBD seperation liquid/liquid extraction

Hey @Future A while back you posted a liquid/liquid PH adjusted wash for THC separations from cannabinoids on your IG Could you post that up in the forum? How has the guess and check gone? Thanks man!

THC isolation from crude CBD oil

I just wanted to add this educational video for those of us without a chemistry background to get a better understanding of what is being discussed using these LL extraction methods mentioned above. [CHEM117 04 Liquid Liquid Extraction Fundamentals]
