ABSTRACT:
In the process of converting alkyl substituted aromatic hydrocarbon to nitriles by ammoxidation where the aromatic hydrocarbon compound, oxygen and ammonia are reacted in the presence of an ammoxidation catalyst under ammoxidation conditions to obtain the nitrile, the improvement of supplying the total amount of ammonia reactant to the reactor as an aqueous solution of ammonia, carbon dioxide and their hydrolysis products (e.g. an ammonium carbonate solution). The major advantage of the process is that it achieves excellent conversion to nitrile without excessive burn of ammonia or organic reactant and avoids the necessity to separate ammonia from off-gases since the aqueous ammonia and carbonate containing solution is suitable for recycle.
