Hi guys,
I was back at my favorite restaurant this morning, and luckily, was seated next to this fellow describing for a friend his first DMT Re-X process - well, his first ever Re-X actually. Below is a list of the steps he followed and some pictures he had uploaded to a website, the URL for which I seem to have misplaced after they were downloaded.
Anyway, he described the following, which yielded roughly 351 mg crystalline material from about 400 mg of mostly white product, which was previously retrieved from powdered MHRB using a very straight forward STB extraction. He tried following the steps outlined in the MIT video, which he found in a sticky post by SWIMfriend back in the Nursery.
Initial dissolve:
1) Heptane was heated in a water bath to 90*C.
2) Enough heptane was added to dissolve the product (~40ml), and the solution allowed to heat for five minutes. Afterward, the solution was clear, yellowish, with no discernible solids.
-------------------------------------------------------------------
De-coloration - Hot Filtering:
3) A small amount of activated charcoal was added and stirred well with a glass rod. A noticeable decrease in the yellow color occurred. The solution was allowed to heat with the charcoal for another five minutes.
4) Prepare filter by placing fluted filter paper into glass funnel, and funnel, into flask.
5) A fluted filter was prepared by adding a coffee filter to a glass funnel over a volumetric flask.
Hot solvent was dripped on the filter paper to heat it.
The solution was poured through the funnel to remove the charcoal. This did NOT work entirely. Small grains of charcoal made it through he coffee filter.
The process had to be repeated using Whatman filter paper - 125 cm Fast paper, folded to create the flutes. The Whatman paper grabbed all the charcoal.
----------------------------------------------------------------------
Reheat and Allow to Sit
6) After filtering, the solution was again allowed to heat for 10 minutes.
7) The solution was removed form the heat bath, placed in a neoprene sleeve to insulate, covered with foil, and allowed to sit for until reaching room temperature.
8 ) The foil was removed so the heptane could evaporate, and the beaker allowed to sit for four days undisturbed. The final 24 hours was spent in front of a box fan running on low to help remove the heptane.
---------------------------------------------------------------------------
Overall, he's happy with the result, but thinks he can do better next time and reduce the loss.
