Verfahren zur Herstellung von O,O-Dialkylthiono-phosphorsäurechloriden

Production of O,O-dialkylthionophosphoric acid chlorides of the general formula: in which R is an alkyl radical having from 1 to 6 carbon atoms, by reacting a dialkyldithiophosphoric with chlorine. A reactor is supplied with O,O-dialkyldithiophosphoric acid and chlorine is added thereto at a tempera...

description Production of O,O-dialkylthionophosphoric acid chlorides of the general formula: in which R is an alkyl radical having from 1 to 6 carbon atoms, by reacting a dialkyldithiophosphoric with chlorine. A reactor is supplied with O,O-dialkyldithiophosphoric acid and chlorine is added thereto at a temperature lower than about 75 DEG C.; following completion of the chlorine addition, the reactor is supplied with a further portion of O,O-dialkyldithiophosphoric acid at a temperature between 0 DEG and 75 DEG C., and the resulting reaction mixture is distilled to isolate O,O-dialkylthionophosphoric acid chloride therefrom.
