Abstract
1444889 Preparation of succinylosuccinic acid diesters LONZA Ltd 29 April 1975 [7 May 1974] 17751/75 Addition to 1356909 Heading C2C A process for the preparation of succinylosuccinic acid diesters from γ-haloacetoacetic acid esters in water wherein the reaction of the γ-haloacetoacetic acid ester is carried out in an aqueous buffer solution of inorganic salts at a pH value of 8-10, the pH being kept constant during the reaction by the addition of a base and the reaction being carried out in the presence of at least one dispersion agent. Diethylsuccinylosuccinate is prepared in the example.
