I plan another interesting experiment.


1. After alcohol extraction do an A/B using as narrow pH range as seems reasonable, i.e. DMT pKa +-2, (6.86 to 10.86). Save the extracted solution. Check yield and product quality.

2. Do another A/B cycle on the saved solution applying wider pH range e.g. 5 to 11.5. Save the extracted solution. Check yield and product quality.

3. "===//===" 4 to 12.5. Save the extracted solution. Check yield and product quality.

4. "===//===" 3 to 13. Save the extracted solution. Check yield and product quality.


The toughest part of the experiment is to test the product quality reliably and objectively.


Melting point measurement looks like an affordable alternative to GS/MC-analysis, but lab equipment for it still costs a few thousand USD. Nobody seems to be using Thiele tubes anymore.
