| titleOfInvention | A kind of preparation method of improved sodium dodecylbenzenesulfonate solution |
| abstract | The invention provides an improved preparation method of sodium dodecylbenzenesulfonate solution, which comprises the following steps: sulfonation, neutralization, removal of Na 2 SO 4 , and static filtration. In the preparation method of the sodium dodecylbenzenesulfonate solution provided by the invention, calcium chloride is added after the neutralization reaction, and the calcium sulfate generated by calcium chloride and sodium sulfate is used to precipitate and remove the sodium sulfate, which can reduce the sulfuric acid in the product. The content of sodium, and sodium chloride is brought in, and sodium chloride is used as a viscosity adjustment salt for most surfactants, which can reduce the subsequent compounding of sodium dodecylbenzene sulfonate and other surfactants. amount of sodium chloride. |
