Process for preparing a basic lithium phosphate catalyst for the isomerization of alkene oxides.

摘要

Process for preparing a basic lithium phosphate catalyst suitable for the gas phase isomerization of an alkene oxide to the corresponding alcohol, in which process an aqueous solution of a lithium compound is mixed in the presence of an alkali metal hydroxide with an aqueous solution of a phosphate salt or phosphoric acid, the process being characterized in that the aqueous solution of the phosphate salt or phosphoric acid is added evenly during a period of at least six hours to the homogeneously stirred aqueous solution of the lithium compound, upon which the precipitated lithium phosphate is washed with water and subsequently calcined.
