Abstract
A method for enhancing the activity of a trilithium phosphate catalyst, useful for isomerizing alkylene oxides to the corresponding alcohols, in which dry catalyst is contacted with an aqueous solution containing a mineral acid such as phosphoric acid, and the acid-treated catalyst is thereafter separated from the aqueous solution, preferably water-washed, and then dried. The amount of acid in the aqueous solution is adjusted so that the pH of the solution in contact with the catalyst is maintained at a value of between 9 to 11.
