Abstract
An improved alkylene oxide isomerization catalyst and process are disclosed. The catalyst comprises lithium phosphate and a neutral inorganic support. A key feature of the invention is that the lithium phosphate is distributed homogeneously and principally on the surface of the support. The catalyst exhibits exceptionally high productivities in the conversion of propylene oxide to allyl alcohol.
Claims9
A process for isomerizing an alkylene oxide to an allylic alcohol, said process comprising heating the alkylene oxide in the presence of a supported catalyst, wherein the supported catalyst comprises:
- (a) from about 5 to about 60 percent by weight of lithium phosphate;
- and
- (b) from about 40 to about 95 percent by weight of an alkali metal-exchanged zeolite.
