Abstract

The invention relates to a catalyst for synthesizing FMEE, and mainly solves the technical problems of wide EO distribution and multiple by-products in catalyst reaction products in the prior art. Byadopting the technical scheme of the catalyst for synthesizing FMEE, which comprises the following components: (a) rare-earth element compounds; (b) alkali metal salts; (c) C1 to C5 alcohols, the technical problems are better solved, and the catalyst for synthesizing FMEE can be used in synthesis of FMEE.

Description

technical field [0001] The invention relates to a catalyst for synthesizing fatty acid methyl ester ethoxylate, its preparation method and application in synthesizing fatty acid methyl ester ethoxylate. Background technique [0002] Synthetic fatty acid methyl ester ethoxylate compound (ethoxylated fatty acid methyl esters), referred to as FMEE, is a new double-capped ester ether type nonionic surfactant. Due to the synthesis of fatty acid methyl ester ethoxylates, one end of the compound has -OCH similar to that of oil 3 , according to the principle of similar compatibility, compared with traditional fatty acid polyether, fatty alcohol polyether, etc., it has stronger decontamination ability, good water solubility, low melting point, strong emulsifying and dispersing ability, less foam, etc.; 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 indus...
