No problem! If I remember I’ll post my findings!

Says 90 where’s the 45?

I go to -20 in a regular freezer, I get another 10% out. I get most out with a room temp filtration.
As long as you’re not drinking methanol you’re fine
First sign of methanol poisoning is a headache, if you dont have a headache you dont have methanol poisoning according to poison control.
Take a shot of ethanol after using methanol if you’re concerned, itll create an azeotrope and you’ll piss the methanol out.
Methanol is a cumulative toxin it builds up in your system

I would get the headaches just from having the fumes and getting it on my skin
I’ve never gotten a headache from the fumes, you must not have had proper ventilation

regardless eye protection is needed with methanol. The fumes will deteriorate your eyes even if you dont have the “poison” feeling or headache along with cleaning the lab coats/clothes frequently. your skin should be exposed as LITTLE as possible when using it/vapors around.

They actually stopped selling carbon chemistry after some solvent was “contaminated” not sure how true it is, but they go through some local suppler now and it’s only 45 a gallon call them! I just ordered 5 pails

All solvent is “contaminated”

Agreed! But thats what they said to me!
All you can do is pick your contaminants, and their amounts.
So ill add my experience to this in case it is of some help to others. I started with 1600g heads/tails distillate and 3100g of ethanol, then split it into 3 separate mixtures for filtering. All solutions were filtered with a 1um filter paper.
Solution A went over a cake of (bottom to top) 100g Celite, 75g Silica 60, 150g T5, 100g MagSil, 75g T41, 50g Carbon, 150g Alumina Oxide using a buchner funnel and 300torr vac.
Solution B went over a cake of (bottom to top) 100g Celite, 150g T5, 50g Carbon, 150g Alumina Oxide
Solution C had 5% Carbon and 5% T5 added to it and mixed to a slurry then filtered over a Celite 545 cake.
Our immediate visual results were lackluster. All three solutions came out at almost the exact same deep red color with zero change, but each cake clearly pulled various chromaphores. I’ve decided to run the exact same side-by-side test but using hexane as the mobile phase instead of ethanol.
One negative thing to notate is that Solution C with the carbon slurry dropped in pH from 7.4 to 5.5 and caused slight isomerization when distilled (to be expected). No pH change was observed from the media cakes.
I’m going to run a mass balance on the oil post distillation to see what kind of cannabinoid loss is present, aside from typical transfer loss.

Great work!!! Thank you
So I can use this in my dewax chamber for butane extraction or just ethonal?
Quick update. This has already been discussed, and I’m aware this isn’t the correct thread, but I wanted to post the update.
The Hexane solution produced a noticeably lighter colored oil, and the distillate went from red to a very nice pale yellow in small quantities and a bright yellow in bulk. We also observed a 36% loss in total mass, presumably 10% from transfer loss, but the majority of it was locked inside of our filter media. We recovered everything locked in the media and added to our bulk “reclaim” oil as we presume it has a heavy concentration of chromaphores.
Pre-remediation (post ETOH wash over the same media structure)

What is the tek for this?
I need to know =)

Yes sir🙏🏼
Well, it’s quite simple, nothing new. I use 10-12 lbs of crushed frozen biomass in 4 separate washbags. Then i run that through 15 gal of etho. I let it sit for 5-10 min then i turn my machine to spin and separate the etho.
Then i take a new batch of 10-12lbs and do the same reusing the 15 gal until i reach 50lbs ran.
That gets filtered through a 6 micron paper on my buchner setup and into the freezer for winterizing. After 24-36 hours i run it through another 6 micron paper and then through 200g bentonite, 100g celite and 60-100g t41 on a 25 micron paper for 5 gal tincture. Then that gets filtered again through 100g celite, 60-100g carbon and 100g alumina.
Then i filter that through 2-3 micron paper and if needed 0.5 micron filter sock cut to fit a 4 inch filter spool.
If you want you can use degumming enzyme in the tincture directly after extraction and first filter before you winterize.
Then rotovap and decarb and into the spd. Vapor temp 165-175c for good separation, 180-195c for faster runs.
Edit: I’m about to put distilled water in the roto flask once the etho has been distilled to try and get any water solubles out of the crude. Prob gonna run 2 gal or more through 2-2.5 liter crude.

Nice tek! Thanks a lot!
I am doing room temp washes and scrubbing warm with carbon before winterization with good results.
20lbs in 5 gal. 10% or better yields on decent trim

Is your tek aimed towards distillate?
