This is a curiosity as much as it is an ask to be referred to a good producer. Can someone please comment on the reason behind conversion liters having the colors that they do, some being drastically better than others and so different to real cannabis d9?
In the attached image you will see product from 3 producers. Can you identify which are real and which are conversion from the image?
I’d also like to learn… also what the major differences between HD9 and D9 and what the differences would be in disposables/carts. Guess I got some searching to do.
It depends on the method catalyst you use and also strongly on the color of cbd used .
Here a picture (of my friends research) of cbd isolates in ethanol
Correctly selected and loaded chromatographic media, and L2L washing procedures with aqueous phase continually modified through various ph levels, followed by neutralization and a brine wash. Follow with appropriate solvent removal and purge, and acquire solvent confirmation testing
For whatever it’s worth - to anyone reading this and interested - I suspect I may have a very easy cleanup solution for color here. It’s not really something so interesting/lucrative to me that I’m willing to spend my own resources on it - but if anyone wanted to donate some various batches of varying quality HD9 I’d be willing to at least run the procedure and return the (hopefully) color remediated material to sender for re-distillation.
That is to say, if you send me colored distillate I can attempt to remediate the color and then return to you the concentrated product material which will then need to be redistilled (I don’t own a wiper, so I can’t re-distill for you).
The most comon way to manipulate color is on spd with powders in the flask
Activated carbon
Magnesium silicate
Calcium oxide
Magnesium oxide
Magsil
Each only max 4 grams to the liter
Neutral activated carbon is the most used but can cause D8 formation
Whenever using powders DEEP vacuum is important since the lower the temp the slower the rxn in the flask
Placing molecular sieves in the vapor path sometimes works
But this is more for isomerized products not so much on natural d9
I truly don’t know the limitations of the chemical technology I’m describing. I use it to remediate something totally different, but I know it improves color in the context I’ve been using it. For all I know it’ll accidentally convert it to d8 - I just can’t speculate on how well it’ll work without trying it out.
