Abstract
Di:chloroacetyl-chloride is prepd by catalytic photo-oxidation of tri:chloro-ethylene at 50-100 deg.C using oxygen or air. The catalyst is of two or three components. One of the components is always azo-(bis)-iso-butyro-nitrile. The other is a known free radical source as gaseous halogen or di:benzoyl-peroxide, or tert-butyl-hypochlorite. Optional third component is a photosensitising agent as methylene-blue or congo-red
