I did my first extraction using AlbertKLloyd's tek. It can be found here:

https://www.dmt-nexus.me...spx?g=posts&t=23972

I ended up with tar, but it worked out ok.
I found it difficult to believe that I would be able to get crystals without using other methods anyway.
So thanks for the tek AlbertKLloyd, I would have thanked you on that thread itself, but I can't post there.

Actually I was hoping that someone would let me know where the latest posts are about this whole subject.

AlbertKLloyd also has some other posts regarding the use of certain solvents that don't heat up much by microwaves and the advantages of this, not all of which I understood, but given the interest on my part I may come to understand them.

I have been reading the cactus posts, and am presently doing a comparison of this solventless microwave tek with the one called the chunk tek, and am right now trying to decide which other one to do, since I have divided my starting material into three, and want to test three different methods. I thought there was a good chance that I would not have to resort to the use of any real chemistry, but it seems I was a bit naive there.

I got a copious amount of tar using AlbertKLloyd's method. Of course that isn't really telling anyone anything. Via ROA I bioassayed one third of the tar extracted by AlbertKLloyd's micro wave tek -- exactly as written, on an eight inch long piece of cactus of unknown genetics, but it was pretty thick (about 7" from point to point). I experienced an energized psychic effect and a light euphoria, some body strangeness. The euphoria was not actually up to the level of my ordinary state, but I wanted to let the mescaline do the work and not input any endorphic elements that I am capable of producing.

the microwave was a fast and easy method to produce tar or tea. Though, I have as yet nothing to compare it to regarding the amount of product. But tomorrow i will have the results of the same amount of cactus using the chunk method. I am presently determining one more test.

my goal is to have about a half a gram of x of some quality, that were produced with as close to food quality as possible. I would like to have this for St. Quantums Day (Spring Equinox), in case I have guests.
I am thinking that this microwave method with the right solvents, as AlbertKLloyd mentioned somewhere in the main cactus area, may be the way to go. Although I am just guessing at this point. I would like to tinker around with it. There must be some kind of pyrex pressure cooking device that one could put right inside a microwave oven. When I learn enough I will get together with one of these companies that make food grade demulsifyers that they will custom compound for the customer's use. These things are for sale for the food industry to keep everything separated.

I guess eventually I will learn enough so that I know what to ask for. Or is this no longer an issue?

Has the emulsification mess that I have read so much about been overcome? I experienced very little so far with the chunk method with the freezing, but it takes much longer and gives loads of water to handle compared to the microwave one.

I notice that in some other microwave oriented posts that I get the impression, that it is mush more beneficial to use solvents and other chemistry with microwaves, rather than just water. I wish I knew if the microwave with only water route should be abandoned because the use of solvents and AB in a microwave would be so superior, given the necessary safety measures. Which as I understand it, would be, do it outside on concrete with a fire extinguisher handy. Any thoughts anyone?

I like microwaves because they heat water so specifically and efficiently.

Quote:

a good trick is to evap, then re-dissolve in an ethanol solution, filter and re-evap... that batch did involve re-dissolving in vodka, re-filtering, letting it settle and pouring off the liquid and then evaporating again


This method cannot be used to obtain pure clean crystals, but I have seen them form in the resin like residue using ethanol evaporation recrystallization.

there is a lot more discussion regarding MAE* in this thread:

* Microwave Assisted Extraction


I like Microwaves very much, but once you are working with solvents other than water or caustic solutions and or dealing with potential superheating then they pose specific challenges and risks. Alcohol is a decent microwave extraction solvent but poses risks of explosion and fire.

Xylene is rather microwave transparent.
oh...
Please don't call it a tek.

I shouldn't have even called it an extraction...
it is more of a concentration method

I'd avoid using solvents in microwaves at this point
if I had a dedicated space that could deal with the safety issues like venting and fire risks then I would be using microwaves almost exclusively to investigate alkaloid/volatile contents of plants

I would avoid putting caustic solutions in microwaves

avoid calcium rich solutions and PEAs, some evidence suggests that microwaves can assist certain type of chemical reactions and you may lose more product due to conversion using microwave energy and mineral complexes than with other methods.

If I was going to work with obtaining mescaline salts with an MAE then I would do a lot of research. I can't say that I have read of an A/B microwave extraction method, working with caustic solutions has risks already and they can be significant, a microwave can superheat solutions past their point of boiling and then a trigger or shock can detonate them, sort of:
