I managed to get through a first pass on my basic SPD setup though my vapor temps were around 260 indicating a probable leak, due to my inadequate vacuum gauge leak isolation was nearly impossible, (though i have a bullseye coming now). Despite all this my first pass didnt come out all that bad, the room stank but the distillate didnt stink too much. I decided then to attempt a second pass on the body, with the same setup but different pump, welch 1400 (250 ml spd).I had minimal charring in the flask, and It came over more quickly than the first pass but now it absolutely reeks and i had almost no color change. I am hoping to remove the smell as well as improve the color though the smell is more important to me. I am considering attempting another round of winterization at a higher concentration to see if anything else comes out 1:5 (200 proof) or perhaps dissolving it in hexane and saline washing it, then running the hexane solution though celite,bleaching clay and AC. it seems likely that vacuum is my problem and im working to get that dialed in but in the meantime any suggestions are appreciated.
Thanks
my processing so far
cold etoh extraction, winterization (1:10) at -80 *3, filtration through celite and AC *2, decarb, first pass, second pass
Seems a little risky putting plastic in such a high temperature environment, stainless steel glass or copper seems like a much safer alternative. Anyone have experience using tiny boro beads?
