“…Methylcyclohexane has apparently never been isolated from petroleum in a demonstrably pure condition. However, its presence in different crude petroleums has been indicated by investigators, such as Lachowicz (12), Charitschkow (13), Young (14), Poni (15), Mabery and Sieplein (16), and Markownikoff (17).…”

An Oklahoma petroleum was fractionated by distillation into a series of 1°c uts. After removal of the toluene from the fractions boiling between 93°to 101°C, by nitration, and subsequent fractional distillations, most of the heptane and the methylcyclohexane were found to concentrate in the fractions boiling between 98°and 100°C. Both of these hydrocarbons were isolated in a practically pure condition by further distillation through a 35-foot laboratory column. For the final fractionation of the material by equilibrium melting a specially
