Hi guys,
should be in DMT Extraction-STB thread, but I don't have access there. Please move it if you can.
This post is meant to be purely informational for someone who might think the same way as me - to add plenty of NaCl and don't have to bother with emulsions.
Well, I am just in the middle of STB MHRB extraction, from powderized bark. I have decided to test how good is NaCl at preventing emulsion problems, so decided to go with (rather low) 10ml of water for 1g of bark and 1g of lye. Vessel was left one day with occasional shaking before np was added. After additon the mixture was violently shaked for about 3 minutes in total. Plenty of air in the vessel allowed to shake it really well.
After few minutes two layers separated perfectly, without any "emulsion" layer in between. The problem was that what was missing was not the emulsion layer, but the np layer. The top layer was consistent emulsion, without any bigger bubbles. The bubbles were impossible to see by eye, they were very small. The emulsion was very stable.
In short, emulsion was separated, excess water wass added - nothing. Excess (more than could be dissolved) NaOH was added - nothing. Excess (more than could be dissolved) NaCl was added - nothing. 60C bath with stirring for about one hour - nothing. 20 minutes heated on vibrating washing mashine - nothing.
I will try alcohol and water washes and let you know whether it worked.
*EDIT : Emulsion was solved, if interested, just read on...*
But the result is : DO NOT EXPECT WONDERS FROM NaCl FOR EMULSION PREVENTION. At least for some kinds.
NaCl helped me a lot with mescaline extractions, but here it is another tale...
