SULFONATION OF n-PARAFFINS
Linear secondary alkane sulfonates are produced by the reaction between sulfur dioxide and n-paraffins in the range of C15-C17.
The reaction is catalyzed by ultraviolet light with a wave-length between 3,300–3,600Å. The sulfonates are nearly 100% biodegradable, soft and stable in hard water, and have good washing properties. Sodium alkanesulfonates for detergent manufacture can also be produced from the free-radical addition of sodium bisulfite and alpha olefins:
