Hello all, I’ve seen this subject come up in part of other threads, but feel it would be useful to have a more focused discussion.
For those of us using Non-Polar Solvents for CBD precipitation, what is your experience and feelings on Hexane, Heptane, and Pentane.
I have used both Pentane and Hexane with success and find that Pentane is usually the solvent of choice for many processors. However, does anyone have experience using heptane with success?
Pentane has generally yielded a faster rate of precipitation, given that the final product being a chunky isolation of small crystal formations is not a deal breaker, often only requiring 12-24hrs of cooling.
If one was to try and lower their risk of combustion, then I find myself looking more towards something like heptane.
Lower Explosive Limit comparisons for the three that I have seen would be:

Boiling Point comparisons:
All three are Class 3 Flammable Liquids
