Use

Cyclohexane is a petroleum product obtainedby distilling C4- 400°F boiling rangenaphthas, followed by fractionation andsuperfractionation; also formed by catalytichydrogenation of benzene. It is usedextensively as a solvent for lacquers andresins, as a paint and varnish remover, andin the manufacture of adipic acid, benzene,cyclohexanol, and cyclohexanone.
