Abstract:
The surface activity of these materials is due to the structural features of their molecules. The solubility and relative size of polar and non polar part in relation to overall molecular structure determine the surface activity of such substances. CMC is probably the simplest method of characterizing the micellar behaviour of surface active agents (solutes). The viscosity of Sodium decyl sulfate (SDS) ,Potassium decyl sulfate (PDS) surfactants in alkanol increases with increasing surfactant concentration which may be attributed due to the increasing tendency to form aggregates with increasing concentration of surfactant. The viscosity (η) of cationic surfactants tetradecyltrimethylammonium bromide (TTAB) and hexadeecyltrimethylammonium bromide (HTAB) have been measured in a (methanol+Toluene) systems at different temperatures. The CMC values for TTAB in these systems at different temperature have been determined from the viscosity vs. concentration plots. The CMC values obtained by viscosity are in close agreement with those obtained from conductance measurements The values of molar volume and interaction coefficient have been evaluated from the Vand`s equation . The plots of [log η vs. 1/T] are found to be linear and the values of ∆H* have been calculated from the slopes of the linear plots. The values of ∆H* for methanol+10% toluene systems have been calculated. The values of ∆S* and ∆G* have been also calculated for the same systems from Eyring`s and Gibb`s equation respectively at 400C.Various activation parameters for fluidity of all the surfactants in methanol + Toluene systems were also calculated.
