I use the @Deleted Cbleach in the boiling flask. I use 1kg of heads and tails with 10% Cbleach. When I run it first pass i always get a very dark blue azulene fraction so I use a bump trap on second pass to remove the remaining azulene thsy gets caught in the main body. My test results usually come back less than 30% delta 9 and over 50% delta 8. I assume I’m not getting proper vacuum depth when scrubbing the solution at 120° for 15 min. Any recommendations on what micron is best for the 15 minute scrub
The hybrid scrub method goes as follows:
Heat oil to 90c
Add clay
Mix for 20-30min
Cool to 40c
Add carrier solvent (ethanol or heptane)
Filter clay with a 5um filter
Any time you add acidic media to the boiling flask you will get Isomerization, regardless of your depth of vacuum. If you are doing a 15 minute scrub, then you need to filter the media out of solution before distilling
I would stongly advise against running carbon through a wfe… You are setting yourself up for a bad day
Thank you so much and Congrats as well!!!1
Check out this thread I did a write-up on best practices when using ColumboBleach in the SPD boiling Flask:
Take a look at the previous post ^^
I like to have a layer of sand at the top of the column to avoid disrupting the hard work I put into packing it. By far the most important aspect of separation is proper packing
When in the winterization process should the hybrid scrub be done?
After winterization but before distillation.
Some people winterize, distill 1st pass, hybrid scrub, distill 2nd pass.
I am using a hochstrom for filtration needs. I always seem to get the carbon A through the silica. I can’t seem to get an even pack with the hochstrom obviously because it is so wide. Does cbleach get stopped by the silica and 1 micron?
I also have a hockstrom filter and have very little problem with bypassing…center the filter in there and 2" of silica…cbleach does get stopped!!
gent the filter? I maybe misunderstanding.
Gotcha. It seems I am having some bye pass somehow. The carbon A is absolutely getting though my filtration. Not sure how. I pack a thick silica layer when I do it but somehow it always gets through. Do you pack?
The 1st filtration usually has a few fines that make it thru. On the 2nd pass, all are normally trapped in the cake.
is your silica wet or dry?
I wet load.
I’ve started making a bentonite slurry with 100g bentonite with etho for a total of 300ml. Put into buchner on coarse filter 2-3 micron prewetted. Then 33g bleach with etho for a total of 200ml slurry on that. Filtered 5gal through that, end result was golden etho. Nothing seems to bypass at all.
Maybe regulated pH to 6-7 after finishing using magsil pr?
You put down bentonite (DE) AND then cbleach?
