Hey everyone, sorry in advance if any of these questions are basic knowledge (I tried searching for several of them).

After having read through many of the teks, Q21Q21's first Vinegar/lime tek appeals to me due to how well it's explained and the lack of dangerous chemicals. Before I begin gathering materials though (since this would be my first extraction), I have a few clarifying questions about this tek and teks in general:

Questions about Q21Q21

- Are there any specific downsides to Q21Q21's 1st tek (besides not being able to use freeze precipitation)

- Would you recommend using Xylene or D-Limomeme for this tek?

- Which steps in this tek need to be done one after the other immediately? Which steps could I take a break after to make sure I haven't messed up?

- Any helpful modifications / additional materials I should know about?

General Questions

- Most people seem to recommend Vovin's / Noman's tek for beginners, why is this?

- Do certain teks result in significantly lower / higher yields? (Besides the much more complicated ones)

Thanks in advance for any help with the above questions. One last thing I'm slightly confused about is this evaporation shortcut in the tek, it states that:



I'm tempted to try this in order to save time, any thoughts? Would I just slowly evaporate the vinegar over time / very low flame until I've freebased the product? Would I then just be able to place all of it in a sealed container and then weigh/use as necessary?

Am I missing something? Because this step seems like it would save a lot of time without complicating things as the guide says it does.

Thanks for everything,
Nova

Solvent loss (in a 100g extraction except to lose 100ml of solvent), lower yield (personal experience).


D-limonene works perfectly for the tek and is food-safe. Minimum 300ml per 100g MHRB.


In my experience, it doesn't work. When all the water is gone, DMT acetate starts to evaporate (you can smell it) it but doesn't turn to freebase. You can still smoke it but you can never dry it so it has to stay on the plate (covered to protect from dust).

I recommend that where in the tek it says 'Alternative Next-Steps', you just continue from BLAB step 4B; that way you're guaranteed to have product that's both smokeable and easy to handle. You may actually just do the BLAB tek from the beginning, it's very easy.

Q21Q21 is great; the "dry tek" with Calcium Hydroxide is far superior to excessive water and Sodium Hydroxide, not to mention safer.

That said, limonene is expensive and much more work. DMT Acetate is a pain to work with and not easily converted to freebase. A friend gently heated the acetate until it no longer smelled of vinegar and still reported that the changa he made with it tasted awful and made his throat hurt. He says if he was to repeat the procedure and had to use limonene, he would use FASA and then turn the resulting DMT Fumarate into freebase in the normal way.

He says he generally prefers naptha instead, though. He freeze precips and drains the naptha in the normal way, then adds acetone or IPA to the jar of crystals and pours it into a flat dish to evaporate at room temperature to ensure that no naptha was trapped as the crystals formed (ever seen a bowl of DMT catch fire?)

Thanks for the replies guys, I guess I'll read up a bit more on people's experiences with Q21Q21's tek and DMT Acetate before proceeding.
