Abstract

1474867 2,2,2 - Trichloroethyl chloroformate SOC NATIONALE DES POUDRES ET EXPLOSIFS 2 Dec 1975 [31 Dec 1974] 49460/75 Heading C2C 2,2,2-Trichloroethyl chloroformate is prepared by reacting 2,2,2-trichloroethanol with COCl 2 at an elevated temperature, in the absence of a solvent and in the presence of an organic compound containing a tert-N atom and having a boiling point of at least 120‹ C., as catalyst. The catalyst is preferably N,N-dimethylformamide or dimethylaniline and is usually present in an amount of 0À5-7 molar per cent. A reaction temperature of 100- 105‹ C. is advantageously employed.
