@tweedledew how has this been working out for you?
We are getting our chromatography setup this week and we’ll have some fractions with methanol and water. I think doing an LLE like you are doing might be a better way of recovering the cannabinoids rather than straight evap.
I’m gonna go slightly out on a limb and say yes, with some possible slight parameter changes from slight differences in properties. So I imagine you are more interested in CBD since it’s coming from hemp?
I’ve been doing clay and AC at the same time, the follow with DGC and water wash- then dissolve 2:1 pentane/oleo and water wash as per the CC SOP
I’m thinking to just get rid of the water wash step, instead dissolve the hot scrubbed and degummed oleo in methanol, winterize, then pull with pentane. sound good?
Have you done a freundlich isotherm to calculate the efficiencies/equilibriums of the solutes absorbed by absorbant? My humble opinion with our refineries is more or less is the proportional steps taken and the efficiency that compounds with each step. Saves a-lot of money and time - economies of scale.
In short…even tho you are trying to removing any impurity - pigments, etc - they each have a chemical benefit or baggage involved at certain steps in the process.
I think both ways are pretty good - if you want i can look in depth on the one you are thinking about. I personally like water. There is alot you can do with it. Cheap and easy.
Tbh I’m not exactly sure what you’re trying to say or what your point is.
I’ve done side by side comparisons on the same material and the scrubbed material is always light because of less bandwidth.
I can take warm extracted alcohol crude and make it just about water clear with this SOP ( I developed the one I posted above ) several ppl here have used this to fix messed up colored distillate without Clay’s in the flask or chromatography.
It works, it might not be “optimal” but for efficiency it is, and someone who wants “optimal” isnt going extract with warm alcohol for extraction. I only use this on warm extracted alcohol crude.
If you carbon scrub first you are removing tocopherols. They stablize oil at least in “harsher” environments. You are also discounting the phospholipids that compete for space with the chloroplast on binding sites. Thus when you have reactors that need one ton of absorbants it is in your best interest to be efficient. All my question was is what is the reasoning behind it AC first.
Theres no particular reason besides efficiency, I always use 5% no matter what when I use absorbents so not sure why I’d be using a “ton”.
I gave you 2 different answers as to why I do what I do and you came back with another question.
Try this SOP and then come and try and pick it apart. It does what it needs to (makes dark red disty or crude golden with no clay in the flask and no chroma) even if on paper you need a “ton” of absorbants (which you dont).
No no no- I need you and @Kingofthekush420 to keep this somewhat heated debate going cause I’m sitting here just taking notes like mad and coming away with too much good info- y’all are both goldmines thank you for the data and insight
