Anionic surfactants secondary alkanes sulfonates and alpha-olefin sulfonates

Secondary Alkane Sulfonate (SAS) Anionic surfactantsSecondary alkanesulfonates are relatively new productsSurfactants . It is produced by reacting sulfur dioxide and air with C12~C14 n-alkanes. This reaction is obviously different from sulfonation and esterification with sulfuric acid, and is called oxysulfonation. The overall balanced formula of the reaction is as follows: R CH2R+2SO2+O2-H2O— K-CH-R-H2SO4 SO2H During…
