A comparison of the levels of unsaturation in α‐olefin sulfonates (AOS) and related derivatives determined by iodination, bromination and hydrogenation techniques showed that quantitative hydrogenation is the only method having wide applicatbility. Although halogenation methods frequently give results in agreement with hydrogenation data, they can show variations with reaction time and composition of the sample. Unsaturation in sulfonate methyl esters could not be determined by halogenation. The amount of † 1 ‐isomer in alkene sulfonate sodium salts determined by oxidative cleavage with periodate‐permanganate was always low compared to that determined by NMR. Oxidative cleavage of the sulfonate methyl esters gave † 1 ‐isomer levels in agreement with NMR results.
