This thread initially existed to get some clarification for my first A/B extraction, but I think I got it figured out now.

I've extracted DMT freebase from MHRB in the past with satisfactory results using various STB and recrystallizing teks. However, my new living situation(apartments...) requires the use of a less nasally-invasive solvent, say D-Limonene? While browsing through the wiki and forums(q21q21 and others), I threw together something that I believe will work out alright. Lets get on with it, this is what I have in mind...



I'm doing my first pull right now, I'll let you all know how it goes once I get a little further into the process. Everything looks alright so far, but I had to add quite a bit more liquid to get all of the calcium hydroxide dissolved while basing the solution. However, the consistency created seems to be working for me. I can't visibly notice any solvent being absorbed by the bark, but we'll see once it's back in the graduated beaker.

Any comments? You guys didn't have anything to say before I edited, but I'm sure you just wanted me to dig around and find the answers on my own, right?

Edited, bumped.

EDIT: I always get off to a bit of a rocky start... While cleaning up for the day, I noticed that my baster was starting to dissolve. I could have sworn that the compatibility sheet for the d-limonene said that nylon was fine, but I guess it isn't. Glass always from now on.
Also, only 200ml of solvent made it out of the solution. Go figure

Triple post, sorry.

I only ended up getting 300ml of 500ml d-limonene out of the bark mixture even after squeezing it dry through a cloth. An extremely stubborn emulsion was noticed between the basic and non-polar layers after draining the liquid. That's where the missing solvent is, right?

Evaporation of the vinegar used to salt the DMT freebase in the d-limonene after each pull resulted in 6.1g of DMT acetate(and I assume, a little excess acetic acid). After freebasing with sodium carbonate, pulling from the basified mixture twice with acetone and evaporating, I was left with 2.7g of thick, syrupy, deep vermillion-colored jungle spice; However, more than a few doses didn't make it off of the evaporating dish due to how hard this stuff is to scrape together. It'll all get smoked though, don't worry

I'll attempt to recover the rest of the solvent from the bark mixture tomorrow, as well as complete another acetone pull from the sodium carbonate mixture as 6.1g acetate turning into 2.7g freebase just doesn't add up to me.

Thanks for existing, everyone. I'm off to visit the elves.

good job! post some pics. i've just been introduced to d-limonene from doing a mescaline extraction and also used quicklime. i usually use naphtha and lye... so this was a great experience getting goodies with food-safe products. if we could see your work that would help to help others with your process, since it's not using alaphatic hydrocarbons

It ended up hardening up a bit and changing colors(camera's flash makes it look more orange than it is, but it is slightly orange) after it sat in the container over night. It's sort of crumbly now which makes it a lot easer to handle, is that normal though?
I don't have any photos of my process, but here's the final product.

I've got enough bark to do two more runs like this and, although it smokes great and does an excellent job at getting me "there", it gives me a quite different experience than I've had with the white crystals resulting from a lye/nahptha STB. I definitely would like some pretty crystals as well as this gloriously messy spice. Is there any way to do that food-safe or should I run over to the art store and pick up some Bestine(heptane)?

Edit: also, does anyone know what the sanskrit symbol on the lid of the container is?
