• DISTILLATION (from the Lat. distillare, more correctly destillare, to drop or trickle down)

distillation of the methyl ester of menthyl xanthate (L . Tschugaeff, Ber., 1899, 32, p . 3333) . It is a colourless liquid which boils at 167-168° C .

When strongly heated with copper sulphate it yields cymene . According to Tschugaeff, the xanthate method alone gives a pure menthene of the above constitution, the menthene obtained from the dehydration of menthol being a cyclohexene-4; and the one obtained by 0 . Wallach (See also:

• ANN

Ann., 1898, 300, p . 278) from 1-menthylamine being a cyclohexene-2 . Carvomenthene, C6H3(CH3)(C3H7), is probably methyl- l-isopropyl-4-cyclohexene-I . It is prepared by heating carvomenthyl bromide with See also:

• QUINOLINE (Benzopyridine), C9H7N
