Well I wich you all the best
Thanks.
This is a example of cristalization at low saturation numbers the first amount comes fairly clean but as soon as gunk starts concentrating there is no way to keep it out of the crystal lattice

Interesting. Thanks for sharing.
That isn’t true. The more impurity in your solution can lead to entrapment of impurities in your crystal structure. The higher purity is also needed to not lock up your chromatography column or destroy your resin with terpenes and crude pigment each run, not just induce crystals. If you do a cold pentane wash you are slaying your yield and continuing down a road that isn’t profitable unless you purchase a chromatography system to run your liquor, which should run you just about the same as a glass short path all the way up to a large steel wiped film depending on scale and quality. No amount of reading can replace experience. It’s not smart to cut corners. If you’d like, hit up some separation labs that charge tolling for chomatography of crude - I don’t think you’ll get the best feedback.

So it isn’t possible to produce isolate w/o distillation?
Well decarbing is defenatly neccesary
It is possible, however, I’m sure the cost of chromatography media would very shortly outweigh the cost of distillation equipment. Silica 60 isn’t exactly cheap.

I am starting with decarbed crude. Please read my full post.

Hmm how large of a scale are we talking ?
Not large at all. Just want to get started making like 100g batches.
Good point. I will continue to research.
So experiment away and show us your results. 100g at a time is a great R&D size- I suggest utilizing a DCVC chromatography column packed with activated alumina, it’s a cheap packing material and does good work on removing pigments

Thank you. I will report back with results. I just so happen to already have some alumina on hand.

You might also be interested in trying some LLE purification- working between methanol and alkane with a higher BP than pentane (heptane being the star choice for me due to its lower toxicity than hexane and it’s easier to work with when it’s not rapidly evaporating into atmosphere like pentane does)
Adsorbants will be your friend here - a pull past a CRC stack would be something to look at
This post is a world salad I’ll edit it in the morning so it’s coherent. Happy full moon

You’ll need some serious additional purification steps if you want to see yields on Crystalization that won’t put you out of business

Higher purity = higher yields.
There comes a point when contaminants and other cannabinoids prevent crystallization.

That’s all it takes, there is no need for chromatography for CBD isolate
These threads always read to me as someone who just wants to skip a certain step(usually distillation) due to cost or skill involved. People turn to chromatography as a magic bullet without realizing the huge amounts of solvents involved, expensive media’s, and long recovery times for solvent management .
It’s like hey guys, I get the process y’all are using but I’m too cheap to pull it off. What’s a way I can do what y’all do but cheaper and easier then you are currently? Isn’t that what business is all about?

Possible and Profitable are two very different things. Wouldn’t everyone just be isolating from crude if it was profitable or do you think everyone just like wasting time and money?
