I've never had any emulsion. What's causing it the vinegar? Is it reacting to impurities and causing it to form in the EA?

Would you say it's a better idea to crash it out with another acid than use 'wet' vinegar? As in do you think it's a better idea to crash and decant rather than use a wet style approach and mixing a 'wet acid' with the EA?

I thought of using hydrochloric acid but I think I recall someone saying it could breakdown the EA a bit and thus potentially more impurities would crash out. I would imagine using just NaCl wouldn't work either as the harmla needs to be in an acid form to give ions to. (If my understanding is correct on that).

I'm sure there is a more selective acids other than say citric acid but perhaps whatever acid is used needs decanting from the EA. Maybe water doesn't help (ie water in vinegar). This would make sense as the citric acid crashed out like crystals not goo when a chemical dry was preformed. I would think by going straight from EA to acidic pull to manske, without separating the steps would add more impurities due to the concentrations of alkaloids present and low concentrations of solutions. I could be way of the mark here or misunderstood your process.

I also wanted to know your thoughts on using NaOH as a base to crash out freebase harmala (heard it's cleaner and better yield (that could be wrong), then do mini EA A/B at the end to clean it up but this time crash with sodium carbonate. Wouldn't add much more time to the Tek maybe another 30mins.
