Could it be possible that the final product is contaminated with CAOH? I read about the water solubility of CAOH and its only 1 grams per 100ml. Is it possible that this 3 grams (based on 300ml water) could migrate to the limonene layer and then to the vinegar?

Also my seperatory funnel was bought second hand so I don't know for sure what kind of substances have been in there. The glass looked clean but there was a kind of sweet odor (and I read that poisonous substances often smell sweet for instance cyankali) in it. I read on internet that you should wash it with acetone and after that with water to clean out potential leftovers. I did this 2 times. The odor was gone after that and the glass looked totally clear. Could there potentially dangerous contaminations in my acetate? I want to try the acetate this weekend at low dose but don't want to risk my life for it. I know it is hard to tell but maybe someone with chemistry knowledge can confirm if my cleaning method was sufficient to eliminate dangerous substance leftovers.

I posted the question about the cleaning procedure on a pro-chem forum. It turns out that washing with acetone and water is not enough to clean all possible left overs. The best way is to fill it up with chlorine and let it stay for a night. After that wash with water-> acetone-> water. Even then it's not sure that possible carcinogens are all gone.
Their advice was: if for consumption always buy a new one if you don't know for sure what happened with a second hand. Which is very logical but in my enthusiasm ignored.

So my first extraction was only for gaining experience unfortunately. This weekend I'll butch another cactus and going to make a resin from it as I'm so ready for this experience. I'll order a new sep funnel and go for the HCl route soon.

As for the CAOH; does anyone knows if it is possible that it migrates to the limo?
