Title:
METHOD FOR PRODUCING (POLY)ALKYLENE GLYCOL MONOALKYL ETHER
Document Type and Number:
WIPO Patent Application WO/2024/085256
Kind Code:
A1
Abstract:
A (poly)alkylene glycol monoalkyl ether is produced at high selectivity and high yield from an olefin and a (poly)alkylene glycol. The present invention provides a method for producing a (poly)alkylene glycol monoalkyl ether in which an olefin and a (poly)alkylene glycol are reacted, using a crystalline metallosilicate as a catalyst, in the presence of a solvent to form a solution having a homogenous liquid phase; the solution is then separated after the reaction at a temperature lower than the reaction temperature into an upper layer containing mainly the olefin and (poly)alkylene glycol monoalkyl ether and a lower layer containing mainly the solvent and (poly)alkylene glycol; and the (poly)alkylene glycol monoalkyl ether is then obtained from the upper layer.
