Veggie oil tek help/q21q21

Hey all, first time posting. Trying to extract using q21q21 tek substituting limonene with vegetable oil. I am now at the step where i have the vinegar and oil in one container, the solvent/oil is separated from the vinegar but i have some white residues in the vinegar which i have no idea what they are. The oil was filtered and completely transparent to the eye before the vinegar was introduced. Also now after the introduction of vinegar and some agitation the oil got cloudy and after they separated the vinegar has some residues in... I will post some photos below. Any one with a clue what it could be?

Hi. It's probably calcium acetate. This is very likely to form if your oil wasn't clear of lime particulates after the pulls - which, to be frank, is very difficult to avoid. You may also have a kind of soap scum from the lime reacting with the oil.

These are educated guesses though, and it would be easier to diagnose things if you could give a precise and detailed description of what you've done throughout the extraction up to this point.

There's a reason which veg oil teks never really caught on, and they were bad enough with sodium carbonate as the base.

Did you really follow all the steps exactly as in q21q21's tek (other than the solvent, of course?

Wiki - Q21Q21's Vinegar/Lime A/B Extraction Tek

This tek is not Q21Q21's original idea but rather a culmination of many people's ideas. It is NOT perfect so if you can think of a better way to do ANY part of it then try it and PM me if it works! The tek is written in first person but they are...

I tried to follow as much as possible. reason for using this tek is in my area the only naphtha i find is the lighter fluid which will not pass the vap test. i have on the way some limo coming but i thought to give a try whith some MHRB and the oil. what i did is
  1. add vinegar to bark (maybe a little more than what was in the tek) and warm it up for about an hour.
  2. then aded the lime to desired consistency and let for 24 hours.
  3. tried to add solvend/oil, had nasty emulsion all over the conteiner, it was a mess. I managed to separate the oil with the pipet and some heat and passing it through coffee filters.
  4. aded the vinegar and now i have the fotos you see.
If its calcium acetate, can it be just filtered out ? Separate the vinegar and filter it will do the job ?
 
Update with the situation, i decided to take out the vinegar. I used a pipette. It seems after taking the vinegar out that whats in it is an emulsion of tiny bubbles i think. When i put the vinegar in a container the white stuff disappeared and only some bigger oil bubbles remained. I will let it sit for a while and come back again.

Glad to see you appear to be making progress. It got too late last night before I could reply, but you did what anyone else might have told you anyhow (y)

Vibration can sometimes help with breaking an emulsion btw.

We're not alone in having had similar problems using lime paste and limonene (in most other cases but yours); one of the causes may be due to insufficient moisture in the lime paste meaning lime particles get released into the non-polar phase.

I think limonene and, especially, vegetable oil have a higher viscosity, surface tension, and/or wetting ability than things like naphtha, heptane or ethyl acetate, making them intrinsically problematic. There are issues with reactivity too, be that saponification, oxidation or whatever. It's a matter of weighing up a whole list of pros and cons when deciding which solvent to use.

Anyhow, that's enough rambling. I'll still be interested to see how this works out - keep us updated!
 
Mayonnaise is made from egg, oil, and lemon juice/vinegar.
Seems like an almost certain path toward emulsion. Or at least it would be for me, as I am no more newborn babe hoping to become a beginner when it comes to extraction tek.

I'm curious: what is the purpose of oil in such a tek, anyone?
 
Afkolemonos said:
It is used as the polar solvent. Thats the material that will take out the spice from the base solution. I replaced limonene with it because it didn't arrived yet. Also i am not a chemist, this is what i understand it does from the research i made.

How do you get the spice out of the oil? Since it doesn't evaporate cleanly or quickly (relatively speaking) and I'm not sure what it would do in a freezer, I've never tried to freeze oil.

Check the q21q21 tek that is posted above from transform. It is the same path used for the limonene tek. Also check this out Sunflower Oil Tek
 
Hey guys. Late update but had lots to do. I managed to finish the procedure. Had to filter out the vinegar a lot of times because i concluded that the white stuff was tiny micro bubbles of emulsion. I read somewhere that using coffee filters saturated with water keeps oil out. I did that and it worked but it needed 3-4 times filtering with different filter each time. Anyway i ended up with a tincture of about 15 ml which i think its too much but warming it more it was getting too thick. I tried some but had no effects. So i think it might be to little spice in it. Do you think using method 6 Here will help concentrate the spice? Do you have any suggestions how to concentrate the spice? I think i got too much other stuff in it.
I attach some photos of what i have now.

Ok. Will try that tomorrow. One more question. I want to extract the rest of the bark using naphtha. The issue is as i mentioned in my first post that the naphtha that i can get has residue after vap test. Can i do the naphtha extraction and then use vinegar to get the spice out of naphtha and then do the acetate conversion with the sodium carbonate and IPA to get clean product?

That may be fine but first give the naphtha a couple vinegar washes before using it, so that when you backsalt the dmt into vinegar there won't be anything from the naphtha that would transfer to the vinegar along with the dmt. Also use the highest proof alcohol you can get to minimize the chance of getting soda carb in your final product.

Cheers, nice one. I think i read that before somewhere in the forums. Thanks for reminding me that.
My IPA is 99.5% says on the bottle. Is it ok? Or i need higher?

If it's not freshly opened on first use, it will have absorbed moisture from the atmosphere. In such an instance it's desirable to use an efficient drying agent so that the water content can be minimised immediately prior to use.

Freshly purchased. Still not opened. Will keep updating as soon as i got results.
