PR-8152A CATALYTIC PROCESS FOR PREPARING DIALKYL PHOSPHORODITHIOIC ACIDS The formation of dialkyl phosphorodithioic acids by reacting phosphorus pentasulfide with an alcohol is catalyzed by using an organosulfur halide catalyst for the reaction. Representative classes of organosulfur halide catalysts include the sulfonium halides, the sulfoxonium halides, and polymeric sulfur halide materials. |
