Appearance: Usually a colorless to light yellow transparent liquid.
Solubility: Soluble in water and a variety of organic solvents, with good water - solubility and oil - solubility.
HLB Value: Around 10.7, with strong hydrophilicity and good emulsifying performance.
Other Properties: Density is about 1.06 g/cm³, melting point is 44 - 46 °C, boiling point is 250 °C, refractive index n20/D is 1.495, and hydroxyl value is 110 - 120. It has excellent resistance to hard water, acids and alkalis.
Product Characteristics:
It has excellent emulsification, wettability and dispersibility, which can evenly disperse oil substances in water to form stable emulsions, and can also make solid particles evenly dispersed in liquid media to prevent particle agglomeration.
It has outstanding detergency and wetting properties, which can reduce the surface tension of liquid, make the liquid quickly wet the solid surface, and improve the spreading property of the liquid on the solid surface.
It has versatile solubility characteristics, low odor and good rinse ability.
Preparation Method: Generally, it is prepared by the condensation reaction of nonylphenol and ethylene oxide under the action of a catalyst.
Application Fields: It is widely used in industrial cleaning, textile printing and dyeing, paper - making, leather chemical industry, chemical fiber oil agent, oilfield auxiliary, pesticide, emulsion polymerization and other industrial fields. It can be used as an emulsifier, dispersant, wetting agent, etc. However, due to its potential environmental hazards, its use is restricted by relevant regulations in the European Union REACH regulation and China's "Priority - controlled Chemicals List".
Packaging and Storage:
Packaging: Usually packed in 200 - kg drums, and there are also packaging specifications such as 210 kg or 215 kg.
Storage: It should be stored in a cool and dry place, and the shelf - life is generally two years.
