Ethoxylated nonylphenol is an irritating substance, the molecular formula is (C2H40) multC15H240, the physical and chemical properties are light yellow ointment, and the melting point is 42-43°C.
It is a non-ionic surfactant, which will not dissociate when dissolved in water. The lipophilic group in the molecule is basically the same as that of the ionic surfactant, and it also contains a certain amount of oxygen-containing hydrophilic groups, such as hydroxyl groups and polyoxyethylene chains. Because non-ionic surfactants are not in an ionic state, they have high stability, are not easily affected by the presence of strong electrolytes, are not easily affected by acids and alkalis, and have good compatibility with other surfactants. Adsorption has many functions, such as good washing, dispersion, foaming, wetting, solubilization, antistatic, antiseptic, sterilization and protective colloid.
Widely used in textiles, papermaking, food, plastics, leather, glass, petroleum, chemical fiber, medicine, pesticides, paints, dyes, fertilizers, films, mineral processing, building materials, environmental protection, cosmetics, fire protection, agriculture, etc. It is indispensable in the development of the national economy.
Long-chain fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acid polyoxyethylene ester, polyoxyalkylamine, polyoxyethylene alkyl alcohol amide, etc. In recent years, the monomer polyether of polycarboxylic acid water reducing agent has been newly added, and the output has been greatly improved. Exceeds the number of traditional daily chemical industries.
Nonylphenol is an important fine chemical raw material and intermediate. Its appearance is a colorless or light yellow liquid at room temperature with a slight phenol odor. It is insoluble in water but soluble in acetone. Mainly used in the production of surfactants, but also in the fields of antioxidants, textile printing and dyeing auxiliaries, lubricant additives, pesticide emulsifiers, resin modifiers, resin and rubber stabilizers. Nonylphenol is an organic pollutant and is called "spermicide".
Ethoxylated nonylphenol is a non-ionic surfactant and a topical spermicidal contraceptive, US Pharmacopoeia 1990 xx11. The product can change the osmotic pressure of the sperm to kill the sperm, or make the sperm lose the ability to swim and cannot enter the cervix, and cannot be fertilized to achieve the purpose of contraception.
