실험 절차

156 G. (1 mole) of 3-methyl-2-nonen-1-ol, 122 g. (1.2 moles) of acetic anhydride and 264 ml. of toluene were combined in a reaction flask and heated. The formed acetic acid-toluene azeotropic mixture consisting of 34 parts of acetic acid and 66 parts of toluene and boiling at 105° C. was removed by distillation through a 11/2 ft. Vigreux column. After termination of the reaction, the reaction mass was washed with 100 ml. of aqueous sodium carbonate solution, 100 ml. of aqueous sodium bicarbonate solution, and finally twice with 100 ml. of water. The desired ester, 3-methyl-2-nonen-1-yl-acetate, having a b.p. of 119°-121° C. at 10 mm. and an R.I. at 20°:1.445, was recovered by fractional distillation.
