Abstract

Olefins are obtained by dehydrochlorinating an alkyl chloride at elevated temperature in the vapour phase in contact with a phosphate of a Group 3B element, preferably boron. The catalyst preferably contains 5-25% by weight of the phosphate on silica gel, kieselguhr or silica alumina. The alkyl halides are preferably those obtained by chlorinating a C10-C17 paraffin feedstock containing at least 95% normal paraffins; unreacted paraffins act as diluent in the dehydrochlorination. Other diluents are methane and nitrogen. Reaction is effected at 150-450 DEG C. and up to 2 atmospheres. Specification 950,975 is referred to.
