Method for the ammoxidation of paraffins and catalyst system therefor.

摘要

Ammoxidation of C3 to C5 paraffins with NH3 and O2 using (1) a mole ratio of paraffin:NH3 in the range from 2 to 16 and a mole ratio of alkane:O2 in the range 1 to 10 and (2) a mixture of particulate catalyst compositions, the first being especially effective to promote formation of an unsaturated nitrile and an olefin from the paraffin, and the second catalyst composition being especially effective to promote the conversion of the olefin to the unsaturated nitrile. Catalytic compositions useful in the process are disclosed.
