ABSTRACT:
A process for the production of unsaturated aliphatic hydrocarbons, such as diolefins, comprising contacting an aliphatic hydrocarbon, such as an alkane or a monoolefin, with a solid heterogeneous catalyst containing labile oxygen under reaction conditions such that a more highly unsaturated aliphatic hydrocarbon is selectively formed in a high space-time yield. The catalyst comprises an oxide of magnesium, an oxide of molybdenum, an alkali metal promoter, and optionally an oxide of vanadium. For example, butane is oxidized in the presence of magnesium molybdate doped with alkali metal oxide to a mixture of products including predominantly butadiene and cis-2-butene and trans-2-butene.
