ABSTRACT:
Acrylonitrile is dimerized by reaction in the presence of a catalyst consisting essentially of (a) at least one metal compound of the formula M(X).sub.n wherein M is magnesium, chromium or manganese, X is a halide and n is a number equal to the valence of the metal M and (b) at least one nitrogen-containing Lewis Base which is (1) a tertiary monoamine of the formula ##EQU1## wherein R.sup.1, R.sup.2, and R.sup.3 are the same or different and each is an alkyl, cycloalkyl, benzyl or aryl radical; or (2) a tertiary di- or poly-functional amine which contains at least two Lewis Base nitrogen groups separated from each other by at least one carbon atom, and which are (a) N-disubstituted amino groups wherein each N-substituent is the same or different and is an alkyl, cycloalkyl, benzyl or aryl radical, or (b) N-heterocyclic groups containing three to 20 carbon atoms; or (3) an N-substituted heterocyclic amine containing three to 20 carbon atoms in the heterocyclic ring wherein the N-substituent is an alkyl, cycloalkyl, benzyl or aryl radical.
