ABSTRACT:
Included is the oxydehydrogenation of saturated dinitriles, for example, succinonitrile, to prepare unsaturated dinitriles, for example, fumaronitrile and maleonitrile. Succinonitrile can be oxydehydrogenated by passing it in a vapor phase over a calcined calcium nickel phosphate catalyst, and the selectivity to fumaronitrile can be varied by the presence of water vapor in the vapor phase feed mixture.
