A good question, but I think you would have trouble separating out the cooking oil after. Winterization could work? The viscosity of the oil might cause an increase in column backpressure decreasing flow.
yeah, it’s off topic: I wasn’t thinking of column, just saline washes.
really just responding to “like oil and water” which was the phrase I used when describing the saline washes for one of my clients yesterday that triggered the thought.
Voices in my head handed me the same stupid idea twice within 24hrs, so I thought I should probably explore whether it was actually stupid…
endpoint of cannabinoids in oil was suggested. 'cause that’s where the client is going anyway. pulling cannabinoids back out with Ethanol also seems viable.
If I had a way to measure pH (locate my pH strips), I’d be on it already. I’ll probably order more & possibly request a meter next week.
So i used a 3 % ratio of C bleach to scrub up some of my crude oil and it has seemed to actually alter the chemical composition of the oil to the point that it is still not finished decarbing after almost 4 days in a vacuum oven at at least 160 degrees Fahrenheit. Not to mention as soon as i pull the oil out of the oven it seems to harden extremely quickly (in less than 2 minutes) in a climate controlled room that is only at 75 degrees. i am quite perplexed by this and was wondering if anyone had any thoughts as to why this is happening ?
What are you favorite mixes to use? Do you have some for certain types of crude, like cbd? Thc? Fats? Colors?gums? Etc
Use DE, diatomaceous earth, and a decently small 11 micron or smaller filter paper in a vacuum filter.
When you say “1000g oleoresin”, is that 1000g of total suspension? Or, would you still say 50g of CBleach in 1000g oleoresin/1000ml ethanol suspension for a total volume of suspension? Hope that’s not too confusing. I guess I’m simply asking if the ration of CBleach is respective to total volume or to the oleoresin, specifically.
The Wet Bleaching instructions per OP
What ratio do you make your alcohol/oleoresin suspension? Is this suspension first run through the short path or unfiltered winterzed?
What filter size do you use?
Where do get silica for filtration. What is a product name?
Hi Soxhlet, what is a dcvc I know what acdc is
Thank you Beaker, very interesting video.
By following the protocol almost exactly according to the video I collected these fractions from already distilled cannabinoid. The only deviation technically was I used hexane instead of pentane as in the video. The order collected was bottom to top left to right. Each fraction is 20 ml just like the video and is pulled through the silica gel column until the column is dry. Then a 5% increase in Ethyl Acetate in the hexane and the next one is pulled through. The first several are clear because of prewetting the column mostly. The main cannabinoid fraction begins after the purple fraction. It goes pretty fast and really not much solvent after to evaporate. Those are 20 ml tubes.
Hey columbo! We bought your cbleach right before this comment about cbleach lite. So we got some helptane for our scrub and it worked great! We’re now wondering how much desirables are lost when performing a cbleach scrub with ethanol. We appreciate your time and hard work.
Nothing is ever “lost” - it would just need to be flushed out of the cake with fresh solvent
I wonder if there is any value to soaking the clay in some water, then heating the clay until the water begins to form vapor and then adding oil for a simultaneous bleaching/deodorizing step. If it worked for those two metrics then it may help with the pesticide metric as well. @Future
I’ve got a funky question. Instead of waiting to heat up your suspension, could you intentionally add some water to it and make CBleach your filter aid topped with molecular sieve beads in a long filter column? When water passes by, there is a fairly substantial exothermic reaction.
Does Cbleach contain bentonite of any form?
Has anyone tried low pressure dry scrub with CBleach? Bleaching earths are often used in controlled pressure… anyone playing with that?
Bleaching Clay is engineered bentonite. The crystal structure is manipulated to become more effective at collecting impurities from feedstock passing through in the right conditions.
I actually recommend a dry/wet hybrid. Do a dry scrub at 90c, cool to 40c, add heptane and filter.
In edible oil manufacturing pressure filtration is normally suggested.
