Taking the results of methylene blue analysis as a yardstick for biodegradability, substituents in the benzene ring of linear alkylaryl sulfonates (CH 3 , C 2 H 5 , OH) greatly deteriorate the aerobic biodegradation characteristics of these products: adaptation time, amount of hard residue, and, to a lesser extent, rate of biodegradation. Replacement of one long alkyl chain by two short ones of the same total length also retards biodegradation. When the benzene ring is replaced by a thiophene ring, adaptation is improved.
