Abstract

A mixed ether-alcohol type surfactant is prepared from the industrial by-product containing ether-alcohol compound through filtering, extracting, and rectifying at 140-260 deg.C. It features that it contains the ether compound chosen from glycol ether, diglycol ether and triglycol ether.

Description

Technical field [0001] The invention belongs to the field of surfactants, in particular to a mixed ether alcohol surfactant and a preparation method thereof. Background technique [0002] At present, there is only a single type of ether alcohol surfactant in the prior art. This type of surfactant has high cost, complex processing technology, relatively harsh requirements on process conditions, and relatively low product yield. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mixed ether alcohol surfactant with low processing cost, simple processing technology and high product yield and its preparation method. [0004] Technical solution of the present invention can be realized in the following manner: [0005] A mixed ether alcohol surfactant, characterized in that it contains: ether compounds; said ether compounds have one or more -CH 2 CH 2 O-structural unit. [0006] The ether compounds are glycol ethers...
