SWIM attempted just this. 1kg MHRB, with this tek. Scaling up volumes of materials (vinegar, solvent, water to salt out solvent, lime...)
SWIM is sure he used more than enough lime, and otherwise followed everything correctly.
(the vinegar acid step was indeed done prior to adding lime, using 100ml vinegar, 100ml water per 100g bark, adjusting to get to described consistency)
~ 2L xylene was used, and during salting out, an equivalent quantity of water was added in steps after the vinegar agitation.
Water was evaporated (took a while, below 100C), and revealed not much other that a brownish tar that is quite dry and does not appear to vaporize too effectively. There wasn't too much of this either.
SWIM added more Lime to the bark to be sure, then did another mix and pull with the same xylene. At this point the solvent was showing a yellow hue, once again clouded up upon vinegar agitation, hot water was added. There did not appear to be much yellowing of the vinegar layer though.
Evaporating this pull now.
Is it possible swim used too much solvent? (though the tek says what was used is fine...)
The bark was from the same supplier that swim previously extracted a good 3.8 gm from 1 lb, using marsofold tek, so swim know the bark is decent quality.
Any thoughts?
*Looking back on the tek, it mentions adding the water to salt out the xylene a little bit at at time:
"-Next add some warm or hot tap water to the solvent(it sinks to the bottom) a little bit at a time and agitate it.
SWIM's initial tests suggest that about 1ml of hot water per 3ml of solvent will dissolve 80% or more of the DMT while the it will take an additional 2-4ml per 3ml solvent to get the rest of the DMT."
Is this implying that small amounts of water be added, then removed before adding more? The picture shown of the salting process shows only a very small bottom layer.
Is this where swim went wrong, by adding all the water (albeit slowly) then drawing it out all at once?
