Abstract
Embodiments are directed towards a process for producing a (poly)alkylene glycol monoalkyl ether. The process includes providing an admixture of a crystalline metallosilicate molecular sieve catalyst and an oxide of a metal and reacting in a liquid phase process an olefin and a (poly)alkylene glycol in the presence of the admixture to yield the (poly)alkylene glycol monoalkyl ether. Reacting the olefin and the (poly)alkylene glycol in the presence of the admixture is at a temperature of 80° C. to 200° C.
