Triphosgene can be easily recrystallized from hot hexanes. It is soluble in alkanes and often sold as a solution in hexanes. The (M,S) isomer can be obtained exclusively from this mixture by recrystallisation from hexanes. It is usually encountered as a colorless or pale yellow solution in hexanes. This capsid has 162 capsomers consisting of 150 hexanes and 12 pentons. Their properties are very similar to those of butanes and hexanes. These reactions are most often run in hexanes. Hexanes are chiefly obtained by refining crude oil. Hexanes are commonly used in chromatography as a non-polar solvent.
