Abstract:
The present invention relates to a process for producing tricarbonitriles corresponding to formula I wherein n is an integer from 2 to 11 by forming an intermediate in the presence of a strong base in a first stage from an aliphatic &agr;-&ohgr;-dinitrile corresponding to formula II wherein n is an integer from 3 to 12, and reacting the intermediate in a second stage to form a trinitrile corresponding to formula I by the addition of acrylonitrile.
