I’m going to try this next week.
Ive made some adjustments.
I decarb the oil fully and open the vac to full blast and bring the oil up to 155c for 30 min to help devolitize.
Then dilute 2:1 heptane:decarbed crude.
If ur extracting from trim and have no inline carbon scrub, then do 2 parts b80/t5 to 1 part oil.
If u extracted from kief/hash or have an inline carbon scrub/filter then u can skip the b80/t5. (Unless u think theres heavy metals in ur oil, then u need to do the b80/t5)
Next run it thru 2 parts AA (ontop) and 1 part magsil (below the AA). For example if u had 1kg of crude, youd have 3kg of diluted crude. And use 2kg AA and 1kg of magsil.
(Powder ratios above can be reduced if ur starting with bho crude, these ratios are for the standard ethanol crude extraction)
After that do some LLE washes. Not much has changed on that part.
Finish with ph 7 and verify the water coming out of the reactor/sep funnel, is also ph 7.
Reduce and recover the heptane in the roto by going up to 155C. (Collect ur heptane b4 u go over 100c on the roto, discard anything that comes off after that, or use it for ur cold traps like i do)
Then transfer to the spd and backfill with argon if u arent planning on running it asap.
Hope this helps
Run the SPD with a hot condenser and try and let 15% of your projected yield to run into ur heads flask before flipping to mains.
About 60% is ur main fraction.
15-20% will be volatiles. And 5-10% will be left as tails.
The heads fraction will be alittle heavy and u can stack that up for another run. You usually end up getting about 20% of ur oil as heads, which 75% of it is good oil, just needs to be LLEd and distilled again.
All in all, im getting about a 75% yield from crced oil, after u account for the rerunned heads. Im hitting 90%+ d9 everytime now and nearly water clear.
I lose about 10% weight going thru the crc/magsil columns but i suspect thats majority nasties that are being trapped.
Ive consulted for 3 decently sized labs now and there all pumping out clear d9 from their wipers now, if u have any questions feel free to ask
I have always done the scrubbing and stuff before decarbing. I was thinking i didn’t want to char any sugars or fats and make them nastier or harder to remove, but i could see how having that stuff in there could have some antioxidant properties keeping you from oxidizing, when heating. I pull vac when decarbing to lower the chance of oxidation as well as get a more thorough devol. Anyone whose decarbed bothy ways, before and after, want to chime in? Killer job and great write up @Thetetraguy
What size reactor do you conduct your washes in?
do you decarb in a reactor?
20L reactor
