I did three acid boils with a pH 2 citric acid solution, filtered, pooled the solutions, reduce to a workable amount and increase the pH to 13.5 with NaOH. Next I warmed the alkaline solution and pulled three times with n-Heptane, and freeze precipitated.
Further cleaning was done by scraping the crystals and doing a mini a/b, salting with HCl, storing the heptane (for later cleaning). I then freebased with a saturated CaCO3 solution, warmed the solution to about 33°C, and added a little amount of n-Pentane and shook vigorously.
Finally, I distilled the n-Pentane at 37°C, the liquid N,N-DMT freebase in my round flask was mixed with a little EtOH, and that's what I put on my watch glass and left to evaporate.
It's incredibly beautiful Multidimensional Fractals Crystal. Thank you for sharing it to us. :thumb_up:
Please, when you make the trip, tell us how it was on force.
You have done well, and that motivates me to read more about chemistry and extractions. Thank you for the motivation.
