| titleOfInvention | Method for improving sulfonation reaction efficiency and production method of dispersing agent MF |
| abstract | The invention discloses a method for improving sulfonation reaction efficiency, which promotes sulfonation by removing water generated in the sulfonation reaction process, and is characterized in that: and in the sulfonation reaction process, keeping normal pressure or vacuum, introducing gas into the reaction system, and carrying out water in the reaction system along with the outflow of the gas. The invention also discloses a production method of the dispersing agent MF, and the dispersing agent MF product is obtained through condensation and neutralization reactions by adopting the sulfonation method. The whole process does not generate solid waste which is difficult to treat, the content of the obtained product sodium sulfate is lower than 5 percent, the heat resistance is 150 ℃, and the product meets the first-grade product standard. |
