I've been working at this for a while. It isn't finished, but I thought I'd stick it in here for you. I can tweak it later. Hope it is of some use.
Pup Tentacle's Lots-O-Water and Patience
(But NO FILTERING!)
Cactus Extraction
Hybrid tek thanks to:
House's tek - for the ideas of LOTS OF WATER and leaving chunks whole for boiling.
and
Kash's tek - for the straight up A/B well explained and presented. Easy to follow with extra clean-up steps included as well.
and
Phlux - for the simple acetone/water Mesc HCL cleanup method. (Easy as pie and quick as a whip)
I did no filtering whatsoever. Settling and decanting was the ticket.. This takes a lot of time, but is easy peasy. Just plan ahead. No good extraction should be rushed anyhow.
350g dried Pervian torch chips (I see no reason this wouldn't work with fresh cactus as well)
16 gallons distilled water (tap water would probably work as well BUT distilled has maximum dissolving power)
1 3-4 gallon stock pot
1 propane cooker
lye (sodium hydroxide)
muriatic acid(hydrochloric acid)
2 1000ml erlenmeyer flasks (or your favorite equivalent)
half gallon glass milk bottle (or your favorite equivalent)
glass baking dishes for evaporation
anhydrous acetone
I use a propane cooker for 3 reasons, 1) So my house doesn't become a steam bath, 2) Propane is cheaper to boil GALLONS of water for HOURS with than electricity, 3) I can do it in my garage whilst sipping fermented beverages and chatting with beloved friends.
1) Boil the chips in 2 gallons of water for 2 hours - add 1/4 cup white vinegar
Let the pot cool, pour off tea into a separate container and save the tea - probably get about 3/4 of a gallon.
Place drained cactus chips in a ziplock freezer bag and freeze overnight.
Repeat process 1 - 8 times, saving the tea after each freeze/boil
***As I'm doing my boils, I'm also decanting the jugs that have stood for a day or two thereby removing settled particulate matter***
You should have between 4 and 8 gallons of tea after this
Reduce to 1300ml - carefully, don't scorch… yadda yadda yadda
****If I'm wanting resin, this is where I stop, dry out the 1300ml of tea (syrup), grind it to powder, and cap it up****
2) Split into 2 1000ml erlenmeyer flasks (the reason for 2 is that I don't have a 2l erlenmeyer flask and I like doing all the parts with caustic stuff in good glass - they're also easier to shake longer in this size for me)
3) Mix 150g of NaHO into 200ml distilled water in 50g increments - place vessel in cooling bath while stirring each time - cap &set aside
4) Basify the cactus tea concentrate with the lye mixture half and half 200ml/200ml in each flask and mix well.
There should be roughly 850 ml of liquid in each 1000ml flask
5) Add 150ml xylene to each flask
shake well - place in hot water bath to separate emulsion
^repeat 3 times and decant the xylene to your milk bottle
repeat Step 5 - 5 times - giving you roughly 1500ml of sweetly laden xylene in your collection jar
(BE CAREFUL! GOGGLES, GLOVES, APRON, APPROPRIATE VENTILATION!!! TAKE YOUR TIME. LOVE YOUR MOTHER)6) Add to THAT 200ml of water AND HCl (I had a jug of 35% muriatic acid) - add until you have <pH7
(BE CAREFUL! GOGGLES, GLOVES, APRON, APPROPRIATE VENTILATION!!! TAKE YOUR TIME. LOVE YOUR MOTHER) shake the shit out of that - shake it like your immortal soul depends on it.
7) Reclaim the now sweetly laden aqueous layer with a pipette or separator funnel
I have a 1l sep funnel - after the shake I poured about 3/4 of a liter of xylene off the top of the bottle and
then poured the rest into the sep funnel - waited for it to separate again and pulled the aqueous layer off the bottom

Placed the aqueous solution in a 9"x13"glass baking dish with a fan on it until completely dry
I ended up using a hair dryer to help it along ( I think I had some excess HCl making it hygroscopic?)
AT this point I have 4 grams of impure mescaline hydrochloride
washed 2x with ice cold anhydrous acetone
AT this point I have 3.5 grams of less-impure mescaline hydrochloride

I took 2 grams of than and undertook Phlux's water/acetone re-X plan.
For final result I'm left with 1.75 grams of tan - seemingly pretty pure (purer than I've bothered to go before) mescaline HCl

Many thanks and much love to all who've gone before me and shared their preciously collected knowledge.
