Abstract
Esters of O, O-dialkyldithiophosphoryl acetic acid of the general formula: <FORM:0948039/C2/1> in which R and R1 which may be the same or different are C1-C3 alkyl groups are obtained by reacting (a) an O, O-di(C1-C3 alkyl) dithiophosphoryl acetic acid with a C1-C3 alkanol or (b) by reacting a salt of an O, O- di(C1-C3 alkyl) dithiophosphoryl acetic acid with a C1-C3 alkyl halide. The salt used in method (b) is suitably an alkali metal salt, e.g. sodium salt. The reactions are preferably carried out at elevated temperature, e.g. at the reflux temperature of the reactants. Method (a) is preferably carried out in the presence of an esterification catalyst, e.g. hydrogen chloride, sulphuric acid or p-toluene sulphonic acid. Specification 803,441 is referred to.
