SODIUM DODECYLBENZENESULFONATE

Sodium dodecylbenzenesulfonate (SDBS) is manufactured through a three-step process: alkylation, sulfonation, and neutralization. First, benzene and dodecene are reacted to form dodecylbenzene (LAB) in the alkylation step. Next, LAB is sulfonated with SO3 to produce dodecylbenzenesulfonic acid . Finally, the sulfonic acid is neutralized with sodium hydroxide  to yield the final product, SDBS.  

Sodium dodecylbenzenesulfonate (SDBS) is an anionic surfactant used in a wide range of applications, including detergents, cleaners, and various industrial processes. It works by reducing the surface tension of liquids, allowing it to effectively emulsify, wet, and disperse substances like dirt, grease, and oil.
