TEK Ethyl acetate approach [CIELO]

[Burnttoast22]

Hi there Nexians.

I was chatting to Loveall on another thread and we got talking CIELO so I thought I better post whats going on with my 2nd attempt at using the TEK.

Anyway the basics: 134g of properly dried Bridgesii pulled with 1.4l EA.

I salted the jar with 16g of CA about 6 hours ago and promptly left it alone. The only agitation was the CA going in.

This is what it looks like as of 5 mins ago.

1x

2x

4x

Pretty

Hope the crystals keep ogrowing and you have a decent yield :d

Some CIELO pron - inspiration and pics from one of my higher yields (Bridgesii 100g powder from full plant -> 3.5% m.citrate when all scraps and washes evapped and collected). Two videos of the citric acid addition phase attached as well.

My citric acid wont dissolve in clear, new EtAc, is it a normal thing? I got two brands of citric acid, but none of them dissolve in it, maybe just a little bit. I added 0,5 gram citric acid to 100 gram EtAc.

But if i add citric acid to the pulled, green EtAc, it will dissolve and form crystals, it looks like citric acid can dissolve in it.
After cristallization, i decanted it, got crystals.
I added some citric acid to the leftover brownish EtAc, and it dissolved it completely.

Why is it, that citric acid wont dissolve in clean EtAC, but dissolve in the pulled one?

Wow!

Thanks mate

Heres what its looking like today.

CA can take a while to dissolve completely in EA.

With the two runs Ive done with this tek; First run I used about 10-15g of powdered CA and it dissolved almost immediately but took a good couple of days and shaking to produce crystals.

2nd run. I left the CA course (added 16g) and it took a good 12 hours for it to dossolve completely but crystals did start forming within about 4 hours.

Some people have had luck with adding a small amount of water (3-5ml) to the saturated EA solution to aid dissolving of CA. I dont know anthing about this so cant really help with that aspect.

But its strange, that in the pulled EtAc it dissolve within a minute, but in the clean EtAc, after a few hours, it looks like almost nothing dissolved. But it works anyway

I imagine thats because the pulled EA has a slightly higher water content.

 

[Loveall]

Yeah, it is probably the water content. Also, citric acid is reacting with mescaline free-base so that helps absorb the citric acid xtals.

Korrupt, we are going by published literature to quote the citric acid solubility in fresh EA. The literature doesn't specify if it was anhydrous citric or not.

However it doesn't matter. Throw any kind of citric acid to the TEK and it works. That little bit of water that is still in the EA seems to help things.

This is an exception to usual lab procedures (where full Chem dries are done). We can make an exception here, because this tek is very highly specialized for the plant and alkaloid to make it as simple as possible. A more general A/B process is more work.

 

[Burnttoast22]

Not as much as I'd hoped for but the crystals are pretty.

I guess I need to find a couple more live cacti sellers as I thought I'd get a bit more than one strong dose per foot with Bridgesii.

The TEK was flawless.

Thanks.
Its an easy way to test my clones and hybrids. It makes selection and testing easier. Im happy, that this method is available

Some Xtal pics from latest extraction. 2 more days to go! Gotta give love to the Cielo Tek

If also doing a reuse brine washing, is it possible to cut out decanting or separating between the sodium carbonate and sodium chloride washes?

Like instead of this:
- Wash used EA with 10% sodium carbonate solution
- Decant/separate
- Wash again with 200ml brine, to a clear solvent
- Decant/separate, and maybe another fridge rest and decant/separate

Just do this?
- Wash used EA with 10% sodium carbonate solution
- Add sodium chloride in excess & stir/shake until clear
- Decant/separate, and maybe another fridge rest and decant/separate

Give it a shot and see what happens. I tried a few combos and the one at the top was the best I found, but there could be better ways for sure.

I don't know if somebody has asked this before, but what other solvents could possibly work instead of ethyl acetate? I already have acetone, IPA, Heptane, Toluene, MEK and DCM.

Would it be possible to dry the paste until almost all the water is gone, and then extract with acetone? citric acid could then be used to salt out the same way as with ethyl acetate.

What about extracting with toluene and salting with benzoic acid?

Tried acetone and MEK, they didn't work for me.

Mescaline freebase does not like to be dry. Somehow it resists being pulled when dry in many solvents. Can't explain why, but that's what seems to happen experimentally.

What about extracting with toluene and salting with benzoic acid?

That is called CITLO. Limonene salted with benzoic should also work (CILLO). We have a general thread for salting by dissolving acids in the solvent in that link.

 

[Jan e Kharabat]

Thanks! Has anyone tried mescaline benzoate? would it be suitable for ingestion?

I was thinking of a way to extract with toluene but make citrate, one idea I have is to dissolve citric acid in acetone and add that to the toluene. Acetone will dissolve in toluene, allowing citric acid to react with the freebase mescaline, mescaline citrate being insoluble in both acetone and toluene will crash out.

I tried cutting out decanting between sodium carbonate and chloride washes but still added additional water to match your original proportions and it worked well! I had a couple batches to go through where I just kept putting each wash on the mag stirrer for 5mins and feeding the sep funnel into a nice routine. Separate issue entirely; I found one of my klean strip MEK substitute cans started rusting and had to toss out the last of it :/ I put it through a few coffee filters before giving up on it. Won't rely on the cans anymore, straight into glass as soon as I get any new cans.

Did they rust when they had salted solvent? I believe citric acid will make them rust, so f you only store neutralized/washed solvent in the cans it should not happen.
