Abstract

The invention relates to a catalyst for the ethoxylation of fatty acid methyl esters, which mainly solves the technical problems of wide distribution of EO and many by-products in catalyst reaction products in the prior art. The present invention comprises following component by adopting fatty acid methyl ester ethoxylation catalyst: (a) alkaline earth metal carboxylate; (b) at least one in Zn salt and Cd salt; (c) N-hydroxyl imide The technical scheme of the invention solves this technical problem well and can be used in the ethoxylation production of fatty acid methyl esters.

Description

technical field [0001] The present invention relates to fatty acid methyl ester ethoxylation catalyst, its preparation method and application in fatty acid methyl ester ethoxylation. Background technique [0002] Fatty acid methyl ester ethoxylate (ethoxylated fatty acid methyl esters), referred to as FMEE, is a new double-capped ester ether type nonionic surfactant. Because fatty acid methyl ester ethoxylate has -OCH similar to oil 3 , according to the principle of similarity and compatibility, compared with traditional fatty acid polyethers, fatty alcohol polyethers, etc., it has stronger decontamination ability, good water solubility, low melting point, strong emulsifying and dispersing ability, and less foam; in addition The product is easy to degrade and is a real environmentally friendly surfactant. Fatty acid methyl ester compounds are widely used in leather, textile and cosmetic industries. FMEE is close to the TX, NP and OP series containing APEO in various perfo...
