Hello,
When doing STB teks using sodium hydroxide.
If planning to pull a full spec jungle intentionally so that the dmt n-oxide can later be converted to dmt via use of elemental zinc powder to maximize yields.. which solvent choice seems most suitable?
If Planning to do a mini AB on the initial chloroform/xylene pulls, by adding vinegar and then sodium hydroxide. Pulling the vinegar lye mini ab with heptane to remove all dmt then crystallize. To leave behind dmt n-oxide in the vinegar lye layer.
Separate heptane and vinegar lye layers. Now pull vinegar lye layer, that now is depleted of all dmt but still has dmt n-oxide in it, with more solvent (chloroform/xylene). This time add vinegar to salt the dmt out of the chloroform/xylene but do not add lye.
Then finally adding zinc powder to the vinegar layer after separating completely from the chloroform/xylene. Finishing zinc conversion on vinegar layer after separating. Adjust ph of vinegar layer to 9.5 with lye and now pull w heptane to retrieve all dmt n oxide which has now been converted into dmt..
Leaning towards using chloroform for initial pulls rather than xylene/toluene. If that isn’t a good choice for some reason?? (any input very appreciated)then I will likely just switch to an A/B tek so I can use DCM. Making sure the base layer is cold before adding dcm. And immediately salting the dmt out of the dcm, once collected from base layer after pulls, via mini ab rather than evaporation. Same story as above use zinc on vinegar layer to maximize yields.
Can someone explain a bit why dcm can’t be used with stb teks? I’d like to understand that a little more so please
Swim had chosen STB bc it was familiar, plus A/B wasn’t an option at that time. But if an AB will also help maximum returns then swim could consider it. Which would make solvent choice easy also lol, I’d def go w DCM. Wwyd??
Open to any feedback, suggestions, warnings, criticisms, ect..
Thank you!
