VERBESSERTES ALKYLARYLSULFONATTENSID |
摘要 |
A surfactant composition comprising:alkylarylsulfonate surfactant system comprising at least two isomers of the alkylarylsulfonate surfactant of the formula: wherein:L is an acyclic aliphatic hydrocarbyl of from 6 to 18 carbon atoms in total;M is a cation or cation mixture and q is the valence thereof;a and b are numbers selected such that said alkylarylsulfonate surfactant is electroneutral;R', R'' and R''' are independently selected from H and C1 to C3 alkyl;both of R' and R'' are nonterminally attached to L and at least one of R' and R'' is C1 to C3 alkyl; andA is aryl; wherein:said alkylarylsulfonate surfactant system comprises two or more isomers with respect to positions of attachment of R', R'' and A to L;in at least about 40% of said composition, A is attached to L in the position which is selected from positions alpha- and beta- to either of the two terminal carbon atoms of L; and wherein further said alkylarylsulfonate surfactant system has at least one of the following properties:said alkylarylsulfonate surfactant system has a ratio of nonquaternary to quaternary carbon atoms in L of at least about 5:1 by weight, when said quaternary carbon atoms are present; orpercentage biodegradation, as measured by the modified SCAS test, that exceeds tetrapropylene benzene sulfonate. |
