Abstract
Decomposition of sodium trichloroacetate in an autoclave yields mainly trichloroacetyl chloride (80%) at 180-200 °C. Carbon tetrachloride, chloroform, and perchloroacetic anhydride are minor products. Only traces of phosgene are formed. These arise from decomposition of perchloroacetic anhydride at temperatures above 200-220 °C (equation (5)). Phosgene is not formed in normal phase transfer catalytic reactionsKeywords
