How is Sodium Styrene Sulfonate produced?
The method of making sodium benzene sulfonate is to first take styrene, which is a colorless oily body with active properties. Mix it with an appropriate amount of fuming sulfuric acid in a special reactor. The kettle has the ability to control temperature and stir to make the two fully blend. During the reaction, the temperature must be strictly controlled to ensure an appropriate reaction. Usually between tens of degrees Celsius, the reaction proceeds slowly, and the sulfonic acid group of the sulfuric acid gradually binds to the styrene. This is a key step. The sulfonic acid group enters the structure of the styrene, causing molecular properties to change.
After the sulfonic acid reaction is completed, a mixed solution containing the sulfated product is obtained. At this time, a solution of sodium hydroxide is slowly added to it to neutralize the sulfated product and the base. The appropriate amount of sodium hydroxide is better, too much or too little affects the quality of the product. The process of neutralization also requires temperature control and stirring to make the reaction uniform. After neutralization, the sulfonic acid group is combined with sodium ions to produce sodium benzenesulfonate.
After that, the mixture is separated and purified. By filtration, to remove insoluble impurities. The filtrate is evaporated and concentrated, so that the water in the solution gradually loses water and the concentration of sodium benzenesulfonate gradually increases. To a certain extent, crystals precipitate. After cooling and crystallizing, more crystals are obtained. Finally, by centrifugation or filtration, pure sodium benzenesulfonate crystals are obtained. In this way, through various steps, the required sodium benzenesulfonate can be obtained.
