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.
Claims15
A process for producing a (poly)alkylene glycol monoalkyl ether, comprising:
- providing a physical admixture of a crystalline metallosilicate molecular sieve catalyst and an oxide of a metal,
- wherein the metal is selected from the group consisting of a Group 3 metal, a Lanthanide element and a combination thereof, and
- wherein the physical admixture comprises the crystalline metallosilicate molecular sieve catalyst in an amount of 25% to 90% by weight, and the metal oxide in an amount of 10% to 75% by weight;
- and
- reacting in a liquid phase process an olefin and a (poly)alkylene glycol in the presence of the admixture of the crystalline metallosilicate molecular sieve catalyst and the oxide of the metal to yield the (poly)alkylene glycol monoalkyl ether.
