Single carbon cut α‐olefin sulfonates (AOS) having 12, 14, 16 and 18 carbon chain lengths and several of their blends were prepared from high‐quality α‐olefins by continuous SO 3 sulfonation in a laboratory falling film reactor. The ultimate biodegradability of these products was studied using a modified shake flask procedure with CO 2 evolution as the major biodegradability criterion. For comparison, commercial samples of a modified Ziegler‐based AOS, linear alkylbenzene sulfonates (LAS), and an alcohol ethoxysulfate (AEOS) were included. The results showed the AOS products bio‐degraded to CO 2 more completely than LAS and slightly less extensively than AEOS. CO 2 evolution decreased slightly in amount and rate as AOS carbon chain length increased in the C 14 to C 18 range.
