چکیده
A new model for micellization beha..-ior of binary surfactant mixtures in solution is presented. A packing parameter, P* , has been introduced to describe the nonrandom mixing in mixed micelles. The significant feature of this model is that it considers asymmetric behavior ofmicellization in binary surfactant mixtures and predict5 the changes in the structures of mixed micelles with concentration that are dependent on the overall ratio of the surfactant components and their chemical characteristics. On the basis of the results obtained, a schematic model for the structural changes of mixed micelles has been proposed here. This model can be considered as a generic model for binary surfactant mixtures, \\ith regular solution

Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...

متن کاملMixing behavior of the biosurfactant, rhamnolipid, with a conventional anionic surfactant, sodium dodecyl benzene sulfonate.
The use of small angle neutron scattering, SANS, neutron reflectivity, NR, and surface tension to study the mixing properties of the biosurfactant rhamnolipid with a conventional anionic surfactant, sodium dodecyl 6-benzene sulfonate, LAS, is reported. The monorhamnose rhamnolipid, R1, mixes close to ideally with LAS at the air-water interface, whereas for mixtures of LAS with the dirhamnose rh...
