Abstract

1,200,768. Chloroformates and carbonic esters. FISONS PEST CONTROL Ltd. 5 Feb., 1969 [8 Nov., 1967], No. 50808/67. Heading C2C. Chloroformates of the formula R-O-CO-Cl are obtained by reacting (a) hydroxylic compounds of the formula R-OH with (b) phosgene and (c) alkali in a molar ratio of b: c: a of 1À1 to 1À8: 1À1 to 3:1, R being an optionally substituted alkyl, aryl or cycloalkyl group. Carbonic acid esters, R-O-CO-O-R, may be produced as by-products.
