An investigation of the methods for the preparation of methyl chloroform and an attempted condensation of methyl chloroform with malonic ester (1936)
AuthorsAdams, A. F. R.show all
Since the reports of the methyl chloroform or 1.1.1 trichlorethane given by various early workers, the methods of preparation have received very little attention. The early reports are summarized in “Beilstein’s Handbuch der Organischen Chemie,” 4th edition. Vol. 1 p. 85. By the action of chlorine on ethylidene dichloride, methyl chloroform and other products are obtained (Regnault, Ann. 1840. 33. 317) and Stadel. 1879. 195. 184). The chlorination, in light, of ethylidene dichloride (1.1 dichlorethane) gives a mixture of 1.1.1. and 1.1.2. trichlorethanes (A. 1978. 368) p. 84. The chlorination of ethylidene dichloride in light is more difficult than the chlorination of ethylene dichloride, and gives as first products both 1.1.1. trichlorethane and 1.1.2. trichlorethane (D’Ans. Kautzch. J. Pr. Chem. 1909 (2). 80. 312; A, 1909 (1). 754).
