After redissolving freebase in heptane, I washed in sodium carbonate and activated carbon. I heated a beaker of freebase in heptane on a hotplate, then let stand for several minutes. I then mixed in sodium carbonate and pipetted out the polar water layer. I then added activated carbon. I'm assuming I erred at this point, but fortunately I used very little mhrb as this was a trial run with my new setup, and rightly so. The heptane I recovered from the carbon was tainted black, and I ran it through a vacuum filtration funnel, pouring heptane over the carbon with the vacuum running. I then left the now completely clear heptane to freeze precipitate...and nothing.
