Verfahren zur Ammoxidation von Paraffinen und Katalysatorzusammensetzung dafür.

摘要

Ammoxidation of propane or isobutane with NH3 and 02 using (1) a mole ratio of paraffin:NH3 in the range from 2 to 16 and a mole ratio of paraffin: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.
