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…
