The structural parameters of complex systems of seven kinds of aryl sulfonate(synthesized in the laboratory) alkyl aryl sulfonate(AAS)/n-butanol/n-decane/water microemulsions were obtained by means of a dilution method.We also calculated the standard free energy ΔG_o→i⁰ of transfer from the continuous oil phase to the interfacial region,the standard enthalpy ΔH_o→i⁰ and the standard entropy ΔS_o→i⁰ values.The effects of the average molecular mass and its distribution of AAS on the structural parameters and thermodynamic functions were investigated.The results show that the effective radius of dispersive phase R_e,the radius of inner sphere water R_w,their difference d_i,the average aggerate number of surfactant molecules per drop n,have the tendency of normal distribution N_d、and the total interface area of dispersion phase outer sphere A_d appear to be contrary to the above consequence.The values of -ΔG_o→i⁰ exhibit the tendency of normal distribution(5.36 kJ/mol) S_o→i⁰ have the tendency of normal distribution(26.88 J/(mol·K)) R_w,R_e,n,d_i,-ΔG_o→i⁰,ΔH_o→i⁰,ΔS_o→i⁰ increase while the values of N_d,A_d decrease.In addition,the values of structural parameters,-ΔG_o→i⁰ and ΔS_o→i⁰ change linearly with the average molecular mass of the AAS,the latter two are y=0.0586x=-17.916 and y=0.2203x=-61.275,respectively.
