Through naptha is cheap and easiest to get non polar solvent but it has high boiling point and bad smell. Even when using vacuum chamber and heating with water naptha barelly starts to boil. So itโs better to look for solvents having boiling points below 100C for fast extractions.
Among faster evaporating solvents are pentane, hexane, heptane, also gasoline, toluene, benzol, light fraction petroleum ether, chloroform and so on. But most of these solvents are hard to get and quite expensive, some even canโt be found for sale and may require special permission, also some are sold as mixes of different substances. One available and interesting solvent was hexane with boiling point of just 68C. Endlessness also mentioned that hexane also doesnโt absorb gramine and hordenine:
endlessness wrote:hexane, heptane or other aliphatic hydrocarbons will dissolve DMT but not gramine nor hordenine. Naphtha works fine too since its usually just a mix of aliphatic hydrocarbons, just make sure it doesnt have aromatics mixed in (like xylene etc).
Light fraction gasoline may also work out but I heard it may contain nasty additives. So what other non polar solvents might be used?
