Today I performed the Kash's A/B Mescaline Extraction Tek getting a terrible emulsion and don't know why.
First, after adding toluene to the basic solution, an emulsion formed immediately (no matter how slowly or carefully I poured the toluene).
This thick weird emulsion did not go away even after adding salt and heating (see the attached picture).
Anyway, I continued with 600 ml worth of toluene pulls (200 ml stayed trapped in the emulsion).
The only parts where I deviated from the tek:
1) Maybe I have added too much citric acid - I was not sure whether to add citric after each water change in the initial cooking, so I added it every time to be sure.
2) Maybe I have added too much NaOH - the tek called for 50g of NaOH, I measured pH while adding NaOH little by little - unfortunatelyt pH jumped from 9 to 12.5 so missed the optimal pH 10.
3) I have added a DCM defatting step on the acidified extract.
4) I have added about 20g of NaCl before basifying.
