What Is Ethoxylation?

Ethoxy compounds are non-ionic surfactants that do not dissociate when dissolved in water. The lipophilic group in the molecule is basically the same as the ionic surfactant. It also contains a certain amount of oxygen-containing hydrophilic groups such as hydroxyl, poly Oxyethylene chain, non-ionic surfactants are not stable in the presence of ions, are not easily affected by the presence of strong electrolytes, and are not easily affected by acids and bases, and have good compatibility with other surfactants, on solid surfaces Does not occur strong adsorption, has good washing, dispersing, foaming, wetting, solubilizing, antistatic, anti-corrosion, sterilization and protective colloid functions, widely used in textile, paper, food, plastic, leather, glass , Petroleum, chemical fiber, medicine, pesticides, coatings, dyes, fertilizers, films, beneficiation, building materials, environmental protection, cosmetics fire protection, agriculture, etc., are indispensable chemicals in the development of the national economy.

Ethoxy compounds

Right!

Ethoxy compounds are non-ionic surfaces

Ethoxy compounds mainly include three categories: alkyl ether ethoxy compounds, cyclic ether ethoxy compounds, and amine ethoxy compounds. There are more than 80 major manufacturers of polyoxyethylene ether non-ionic surfactants in the world, and the current output is more than 4.5 million tons. The Italian PI company's ethoxylation technology is mainly used. The United States accounts for 35% of the world's total output. The United States currently produces about 150. There are many types of polyoxyethylene ether non-ionic surfactants, but mainly used in the two major categories of fatty alcohols and alkylphenols. Western Europe and the United States account for 70% and 60% of the total production of nonionic surfactants, respectively. At present, there are more than 600 domestic manufacturers of surfactants, with a production capacity of more than 1 million tons. The main varieties are fatty alcohols, polyoxyethylene ethers, alkylphenol polyoxyethylene ethers, fatty acid polyoxyethylene esters, oil ethoxylates, and alkane. Alcohol amide, ethylene oxide, propylene oxide, polyether, polyhydric alcohol ester ether products have about hundreds of varieties.

Long chain fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acid polyoxyethylene ester, polyalkylene oxide amine, polyoxyethylene alkyl alcohol amide, etc. In recent years, the monomer polyether of polycarboxylic acid-based water reducing agent has been added, and the output has greatly exceeded the amount of traditional daily chemicals.
