Preparation of lithium phosphate catalysts

摘要

A new method for preparing lithium phosphate catalysts is disclosed. The method comprises precipitating a lithium phosphate from a mixture comprising a first aqueous solution which contains lithium and sodium ions and a second aqueous solution which contains phosphate and borate ions. The resultant lithium phosphate catalyst has increased activity and selectivity in the isomerization of an alkylene oxide to the corresponding allylic alcohol.
