I’ve mentioned previously on another thread that I had had problems with an extraction using heptane. It turned out that despite being sold as such the heptane wasn’t heptane as nothing freeze precipitated from it but adding FASA did result in something precipitating out. I’ve now pulled some MHRB with it (after pulling with Bartoline naphta) and evaporated it to yield a small quantity of yellow waxy sticky product, the effects of which are quite pleasant and described here

What I want to ask if if anyone can help identify the solvent, which I’ve been calling non-heptane. I know it is more non-polar than heptane, works with FASA, doesn’t freeze precipitate spice, isn’t Toluene or Xylene (as it doesn’t evaporate in their distinctive spotty patterns but as a white coating on the evap dish which scrapes up yellow), is clear in colour & smells the same as any other hydrocarbon solvent. I’ll add a pic of the extracted product incase anyone’s yielded similar but I won’t be able to do this for a while as I’m waiting for a new computer & can’t post pics from my work pc. Still if you’ve yielded a similar mellow yellow product with similar effects let me know what solvent you used as I’m really interested in indentifying this non-heptane.

would you happen to know its boiling point?
if it glows significantly in a black light, it's an aromatic hydrocarbon solvent (like toluene or xlyene). it won't glow if it's heptane (an aliphatic, straight-chain hydrocarbon)

I'll check this out tonight.

It starts boiling at 84 degrees centigrade.
There is a purple flourescence when a UV torch is shone through it i the dark.

hmm..sounds like some sort of aliphatic, although aliphatics don't really fluoresce unless unsaturated (has alternating double bonds)

aromatics start boiling at 80.1 (benzene), but glow brightly (blue). benzene has a distinctly sweet smell, as does toluene. xylene smells annoying
