Abstract

The invention discloses an octylphenol polyoxyethylene ether emulsifier and a preparation process thereof. The emulsifier is characterized by comprising, by weight, 25-30 of octyl phenol, 70-75 of epoxy ethane, 0.2-0.4 of catalyst and 0.8-1.0 of neutralizing agents. The octyl phenol and the epoxy ethane serve as raw materials, the octylphenol polyoxyethylene ether emulsifier is synthesized, and the octylphenol polyoxyethylene ether emulsifier has the advantages of nonylphenol ethylene oxide ether emulsifiers and good emulsifying and dispersing capability, is nontoxic and cannot harm human bodies.

Description

Technical field [0001] The invention relates to an octylphenol polyoxyethylene ether emulsifier and a manufacturing process thereof. Background technique [0002] Pesticide emulsifiers are a class of surfactants. As an important auxiliary for processing pesticide preparations, they can improve the use effect of pesticides, improve the biological activity of pesticides, and bring huge benefits to agriculture. Alkylphenol polyoxyethylene ether is the second largest category of non-ionic surfactants. It is mainly used as emulsifier for pesticides, and is also a good defoamer, finishing agent, emulsifier, and softener in the textile industry. Among them, the number of alkyl carbon atoms of alkyl phenol can be adjusted. The most widely used in industry is nonyl phenol oxyethylene ether. This substance has good emulsification, dispersion, resistance to hard water and oxidation resistance, but this substance Once discharged into the environment, it will quickly decompose the more toxic...
