Abstract
In the process of making dicyanonaphthalene by reacting a di-lower alkylnaphthalene, ammonia and oxygen under ammoxidation conditions, the improvement which comprises carrying out said ammoxidation in the presence of a supported alkali-metal vanadium bronze catalyst, promoted with iron and with a molar ratio of ammonia to dialkylnaphthalene of from at least about 10:1 to about 30:1. The invention also embodies the iron promoted catalyst.
Claims5
A catalyst composition consisting essentially of from about 0.5% to 20% by weight of the total catalyst of an alkali metal bronze and an iron oxide in an amount from about 0.5 to about 25 mole percent of the catalyst expressed as oxides on a support consisting essentially of .alpha.-alumina.
