POLYETHYLENE GLYCOL ETHER DERIVATIVE, NONIONIC SURFACTANT AND METHOD FOR PRODUCING POLYETHYLENE GLYCOL ETHER DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a new polyethylene glycol ether derivative capable of being produced by a simple process in a moderate condition without forming by-products and useful as a high performance nonionic surfactant.;SOLUTION: This polyethylene glycol ether derivative is expressed by general formula (I): ROOCCH₂CH₂(CH₂CH₂O)_n-Q [wherein, R is a 4-18C alkyl;Q is H or CH₂CH₂COOR; and (n) is 2-50 integer], and the nonionic surfactant consisting of the same is also provided. The method for producing the polyethylene glycol ether (I) is provided by performing the reaction of an acrylic acid alkyl ester with a polyethylene glycol in the presence of a basic compound.;COPYRIGHT: (C)2005,JPO&NCIPI
