Abstract

1,210,475. Carboxylic acid bromides. CHEMISCHE FABRIK KALK G.m.b.H. 1 Feb., 1968 [3 Feb., 1967], No. 5262/68. Heading C2C. Carboxylic acid bromides are produced by mixing a carboxylic acid, phosphorus tribromide and bromine in the molar ratio of 3: 1: 1, the phosphorus tribromide being mixed with the acid before addition of the bromine, and then reacting the mixture at a temperature of 0‹-100‹ C.
