Document Type and Number:
WIPO Patent Application WO/2024/085255
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a (poly)alkylene glycol monoalkyl ether, the method being capable of stably producing a (poly)alkylene glycol monoalkyl ether continuously from a starting material olefin without causing a decrease in the yield of the (poly)alkylene glycol monoalkyl ether or a decrease in the catalytic activity. [Solution] A method for producing a (poly)alkylene glycol monoalkyl ether, the method comprising a step for reacting an olefin and a (poly)alkylene glycol in the presence of a catalyst within a reactor, wherein: at least some of the starting materials used for the production is recovered and used again as the starting materials; at least one of the recovered starting materials contains an olefin; and the mass of branched olefins relative to the total mass of branched olefins and linear olefins contained in the recovered starting materials is controlled not to exceed 20% by mass.
