Hexane Honey Oil | Skunk Pharm Research
A hexane extraction is harder than butane or ethanol to purge below sensory threshold, and at the very least, the pool needs to stay liquid so that the remaining solvent molecules can escape. Without vacuum, we typically have to redissolve in ethanol a couple of times and evaporate away the ethanol, to purge the remaining hexane.

A Beginner's Guide to Essential Oils Part 1: Essential Oil
Solvent extraction is often used for plants that are too delicate for steam distillation, such as Jasmine flowers. The most common solvent is hexane, and a few parts per million of hexane do remain in the final extract. While this is by no means toxic, absolutes are sometimes avoided because they are processed using a synthetic solvent.

Vegetable fats and oils. In modern vegetable oil production, oils are usually extracted chemically, using a solvent such as hexane. Chemical extraction is cheaper and more efficient than mechanical extraction, at a large scale, leaving only 0.5-0.7% of the oil in the plant solids, as compared to 6-14% for mechanical extraction.

Hexane
Hexane / ˈ h ɛ k s eɪ n / is an alkane of six carbon atoms, with the chemical formula C 6 H 14.. The term may refer to any of the five structural isomers with that formula, or to a mixture of them. In IUPAC nomenclature, however, hexane is the unbranched isomer (n-hexane); the other four isomers are named as methylated derivatives of pentane and butane.

Liquid-liquid extraction
Liquid-liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.
