For surfactants SDDS, HTAB, HPB.H2O and HPC.H2O the thermo chemical parameters (̅H2-H02) and heat capacities (̅Cp2-C0p2) relative to the pure state, in the pre c.m.c. region at infinite dilution in the monomeric state and at concentrations a little above the c.m.c. for the micellar state have been determined. From these, the enthalpies (ΔHm) and heat capacities (ΔCpm) of micellization have been calculated. Results indicate significant hydration of alkyl parts in the micellar state.Downloads
