Title: PROCESS FOR PRODUCING CYANOACETIC ACID ESTERS
Abstract:
Provided is a process for producing cyanoacetic acid esters which achieves high-yield production of cyanoacetic acid esters and minimizes the generation of by-products. A process for producing cyanoacetic acid esters by esterifying cyanoacetic acid with an organic compound represented by the general formula ROH [wherein R is a C1-10 group selected from the group consisting of linear or branched saturated hydrocarbon groups, linear or branched unsaturated hydrocarbon groups, alicyclic hydrocarbon groups, aromatic hydrocarbon groups and -C2H4-O-R1 groups (wherein R1 is a linear or branched saturated hydrocarbon group, a linear or branched unsaturated hydrocarbon group, an alicyclic hydrocarbon group, or an aromatic hydrocarbon group, each group having 1 to 8 carbon atoms)] in an organic solvent other than the organic compound, wherein both a first solvent, the solubility of cyanoacetic acid in which is 1 [g/100g of solvent] or more at 25°C, and a second solvent which is substantially insoluble in water at 25°C are jointly used as the organic solvent.
