Abstract
In the catalytic reaction of saturated lower aliphatic hydrocarbons, e.g. propane, isobutane, with oxygen and ammonia in gas phase in contact with solid metal oxide catalysts, conversion of the hydrocarbon and selectivity of conversion to .alpha.,.beta.-unsaturated nitrile are improved by using a catalyst comprising a fluxing agent, e.g. phosphoric acid to maintain the catalytic metal oxide e.g. molybdenum oxide in a non-crystalline state.
