ABSTRACT:
Disclosed is a method of making an aromatic nitrile by reacting a benzotrichloride having the formula ##STR1## with a source of ammonia, where Z is R, X, ##STR2## --ROR, or --OR, R is alkyl from C.sub.1 to C.sub.20 or aryl from C.sub.1 to C.sub.25, X is halogen and n is 0 to 5. The reaction is performed in the presence of 0.01 to about 5 wt % of a catalyst having the general formula M.sub.P/2 O or MX.sub.p .cndot.mH.sub.2 O and about 0.01 to about 5 wt % water, as free water or water of hydration, based on the weight of the benzotrichloride, where M is beryllium, magnesium, calcium, strontium, or barium, m is 0 to 6, and p is the valence of M.
