Abstract

The invention discloses tristyrylphenol polyoxyethylene ether sulfonate. A preparation method of the tristyrylphenol polyoxyethylene ether sulfonate comprises the following steps: (1) adding potassiumhydroxide into triphenylethyl phenol, and carrying out a high-temperature continuous aging reaction to obtain a reactant; (2) adding epoxypropane into the reactant for continuous aging reaction to obtain a secondary reactant; (3) adding ethylene oxide into the secondary reactant for continuous aging reaction to obtain a product; and (4) adding sulfamic acid into the product, adding a catalyst urea or dodecylbenzene sulfonic acid, and adding a sodium sulfite saturated solution after reaction so as to obtain the tristyrylphenol polyoxyethylene ether sulfonate. The invention also discloses an application of the tristyrylphenol polyoxyethylene ether sulfonate. A pesticide suspension concentrate comprises the following raw materials: 48% of clothianidin, 5% of the tristyrylphenol polyoxyethylene ether sulfonate, 1% of fatty alcohol-polyoxyethylene ether, 0.5% of magnesium aluminum silicate, 0.02% of xanthan gum, 0.1% of sodium benzoate and 45.38% of water.

Description

technical field [0001] The invention relates to the technical field of pesticide manufacture, in particular to a triphenylethylphenol polyoxyethylene ether sulfonate and a pesticide water suspension. Background technique [0002] Among pesticide adjuvants, tristyrylphenol polyoxyethylene ether nonionic surfactant prepared by ethoxylation of tristyrylphenol and ethylene oxide is widely used, but because tristyrylphenol polyoxyethylene The performance of ether is insufficient. At present, the pesticide suspending agent added with tristyryl phenol polyoxyethylene ether on the market has the problems of low suspension rate, poor dispersion performance, and prone to stratification and bottoming after long-term storage. Contents of the invention [0003] The technical problem to be solved by this invention is: [0004] The performance of tristyryl phenol polyoxyethylene ether is insufficient, and the pesticide suspending agent added with tristyryl phenol polyoxyethylene ether h...
