Uneven results with Q21Q21

[JKW]

100 g of MHRB: About 400 mg of yellow DMT from six pulls.

150 g of MHRB form the same package:
1st pull: 200 mg of fluffy white crystals.
2nd pull: 200 mg of yellow heavier crystals.
3rd pull: 245 mg of fluffy white.
4th pull: 178 mg of yellow.

Pulled with heptane. 1st extraction with Bestine. Second extraction with lab grade heptane.

Same exact process on both extractions, and the material comes from the same bag.

The only thing that changed has been the temperature of the heptane. Before, the water would boil for the double boiler. The last extraction the water did not reach boiling point.

Any ideas why this happened? I can imagine that the heptane temperature will influence the color of the DMT, but not influencing the yield. Appreciate suggestions.

There are multiple unspecified variables. Besides, you used two different solvents so it's not a completely fair comparison.

Did you use the same proportions of lime, water and heptane in both extractions?
Were the soak times at all the various stages of the two procedures the same?
There could well be a qualitative difference between Bestine and lab grade heptane - with the latter being the better solvent, it would seem. Or it could be that the Bestine contains ingredients such as aromatics which reduce the efficacy of freeze precipitation, if that's the recovery method you used.

What does spring to mind is that in the case of the first extraction, the boiling water bath would cause more of the heptane to evaporate and there would be thus a smaller volume of solvent with the consequence being a smaller yield. You would think that the six pulls would have made up for this, however.

Another cause could be inhomogeneity in your plant material, which is hard to account for and seems unlikely but not impossible.

I will have to consider this. Thank you for your insight.

Next extraction will be the exact same soak times ( a variable I did not think of).
