Production method

98% concentrated sulfuric acid was used as sulfonator,Ag2SO4 as catalyst and hydroquinone as inhibitor. Concentrated sulfuric acid: styrene (molar ratio)=2∶1, mass fraction of catalyst 1%, mass fraction of inhibitor 1%. When the temperature is 54℃, the feeding starts, the heating is heated to 70℃ after adding the material, the constant temperature reaction is 2 ~ 2.5h, the brown solution is obtained, and then the sodium hydroxide is neutralized, the sodium styrene sulfonate monomer is obtained, and the polymerization monomer can be achieved by crystallization.

Use

This product is used in dyeing modifier (polyacrylonitrile fiber, polypropylene fiber, polyester, rayon), reactive emulsifier, water-soluble polymer (coagulant, dispersant, container cleaning agent, cosmetics), polysulfur fault (dialysis film, battery, artificial body film), electrification prevention agent (nylon, record paper, polyester), sulfur exchange resin (film), photo agent (micro film) Sheet), plating gloss agent and so on.
