Abstract: The nuclear iodine substituents borne by an iodopyridine are displaced by introducing gaseous chlorine into the mixture at a temperature of from about 100.degree. C. to about 250.degree. C. The displacement of iodine produces chloropyridines, which can then be conveniently separated from the liberated iodine by conventional methods such as distillation.

Abstract: A process for preparing olefins and diolefins in high productivity which involves contacting an aliphatic hydrocarbon, such as butane, with a heterogeneous catalyst composition containing reactive oxygen under reaction conditions sufficient to produce a more highly unsaturated aliphatic hydrocarbon, such as 1,3-butadiene. The catalyst composition contains a glassy silica matrix of specified surface area and macro-porosity into which are encapsulated domains of a catalyst component containing oxides of magnesium and molybdenum. The catalyst has high crush strength and is useful in transport reactors.

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.
