The present invention relates to a process for the preparation of a cyano carboxylic acid ester of the formula
wherein
R1 is a linear or branched C1-8 alkanediyl group; and R2 is a linear or branched alkyl group, a cycloalkyl group, or an aryl or arylalkyl group, wherein aryl is optionally substituted with one or more C1-8 alkyl groups; comprising reacting a halo carboxylic acid ester of the formula
wherein R1 and R2 are as defined above; and Hal is fluorine, chlorine, bromine or iodine;
in a reaction mixture comprising a homogeneous liquid phase, wherein the liquid phase consists of water and an organic solvent,
with an alkali metal cyanide in the presence of hydrogen cyanide, optionally in the presence of a catalyst, to obtain the cyano carboxylic acid ester of the formula (I).
