ABSTRACT:
A process for the preparation of C.sub.4 -C.sub.10 alkyl cyanoacetates by the reaction of cyanoacetic acid with C.sub.4 -C.sub.10 alkanols at a temperature of from 35.degree. to 150.degree. C. and under a pressure of from 70 to 1013 mbar, in the presence of catalytic amounts of acid, while a C.sub.4 -C.sub.10 alkanol/water azeotrope is separated during the reaction.
