production method | 1. 98% concentrated sulfuric acid is used as sulfonating agent, Ag2SO4 is used as catalyst and hydroquinone is used as polymerization inhibitor. Concentrated sulfuric acid: styrene (molar ratio) = 2: 1, catalyst mass fraction 1%, polymerization inhibitor mass fraction 1%. When the temperature is 54 ℃, the material is added, the temperature is increased to 70 ℃, the temperature is reacted at a constant temperature for 2~2.5h to obtain a brown solution, and then sodium hydroxide is used to neutralize to obtain sodium styrene sulfonate monomer, and the polymerization monomer can be reached by crystallization. The reaction formula is as follows: |
