Before the first pass using 200 proof ethanol, i winterized, then wet scrubbed with hardwood charcoal then dry scrubbed with t-41
Stop me if i go astray. I have the degumming enzyme from carbon chemistry. Im going to use a seperatory funnel to mix a 1:1 heptane : distillate solution and then wash it with a low pH brine over and over again until its clean.
What is the best way to lower the pH here? Does it change the ph of my heptane/distillate solution and if so how do I change it back before i rotovap it down?
Then I will winterize. Can i use less of a carrier for this second pass winterization? Because there will be less wax to remove? I used 10:1 for the first pass winterization and scrubbing. Maybe this is not necessary i just figure why not to just to see what happens. Also i did the first winterization in the deep freezer at maybe -10F. Im thinking of doing it this time with dry ice to go down to at least -50F
Is 200 proof ethanol the best thing to use for this (winterization, charcoal scrub, bleaching)? I also have 200 proof denatured with heptane and i also have 99.5% heptane
What carrier solvent is best to use for the hot scrub/wet scrub? What is the best ratio of solvent to use? Does the ratio for solvent for carbon/clay scrubbing change from first pass to second pass? Is there a reason to use more carrier solvent? It just takes longer to recover and im trying to cut all my corners where its prudent.
I do know when i used to make amber glass it would always come out a lighter color if I used 151 to winterize instead of 190. The 190 would cook off much faster and i assumed the extra water in the 151 would be like a buffer and make it less caustic possibly? I dont really know the science behind it
And ISO 190 proof is better than ISO 200 proof? i will add distilled water to my 200 proof iso to make it 190? Will that water freeze in winterization? Does that change how I recover in the solvent in the evaporator?
Is ethanol optimal for the charcoal scrub and/or clay bleaching? Does it change if you scrub wet or dry?
Is 200 proof or 190 better for this? Sorry for all the newb questions.
My next step is building out a lab in a commercial space. I’m currently in the research phase and will gear towards production in a newly outfitted facility.
