In my last extraction I obtained a good quantity of ACRB goo.
I usually get nice crystals because I do a mini a/b before freeze precipitating. This time I decided to skip the mini a/b and I ended up a good amount of goo. I then went on to experiment with the goo (making changa, recrystallizing, etc.) and I came across an interesting observation...
If the goo is dissolved in acetone and left to sit for 24 hours a 'goo-like' precipitate falls out and the slightly cloudy acetone clears up. At this point I have not touched the solution, I am currently thinking about my next move...
I think I am going to separate the 'goo-like' precipitate and then allow the solution to evaporate. I assume an oily substance containing a high concentration of DMT will remain. I will then attempt to recrystallize the oil using the standard methods described in the wiki and elsewhere.
This method of obtaining crystals from ACRB could be easier and more efficient compared to performing a mini a/b. One could simply perform a standard A/B, combine and evaporate the pulls, redissolve the remaining goo/oil in acetone and continue with the mini tek above.
I will report back with results for anyone interested.
