    摘要: A process for producing an acidic dehydration catalyst to convert lactic acid to acrylic acid. The process comprises impregnating an inert metal oxide carrier with a phosphate salt and buffering the impregnated carrier with a base to a pH sufficient to provide the effective dehydration catalyst.

    摘要: Normal olefins such as n-butenes and normal alkanes such as n-butane can be coverted to branched olefin species such as isobutylene by skeletal dehydroisomerization over catalysts preferably containing metals selected from Groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, VIII and the rear earth elements which are deposited upon borosilicate zeolites having pore sizes of at least about 5 Angstroms and containing boron in the framework structure thereof. The borosilicates have sufficient acidity to catalyze the skeletal isomerization of both normal alkanes and normal olefins. The catalysts can be used to produce isoolefins for reaction with alcohols in integrated processes to produce alkyl tertiary alkyl ethers such as MTBE.
