Hexadecane-potassium oleate

Variation of k with for the system water/hexadecane/potassium oleate/hexanol. [Pg.358]

Conductivity measurements were also used to study the structure of the microemulsion, which is influenced by the nature of the cosurfactant. This can be shown (Figure 10.14) for two systems, one based on water-toluene-potassium oleate-butanol and the other on water-hexadecane-potassium oleate-hexanol [17]. The two systems differ in the nature of the cosurfactant, namely butanol (C4 alcohol) and hexanol (Ce alcohol). [Pg.329]

The typical light scattering curves (Sjoblom, 1978) show the increase of scattered intensity characteristic of micellar formation first at relatively high water concentrations. The example in Fig. 5 is from microemulsions with 50% by weight hexadecane stabilized by potassium oleate and pentanol (Sjoblom, 1978). The scattering intensity below a water concentration of 30% by weight (counted on water, svirfactant. [Pg.205]

In a series of papers published a few years ago (39-41), Shah and co-workers reported data gained from correlated conductivity, birefringence, interfacial tension and NMR investigations performed on water-hexadecane systems using potassium oleate and hexanol as... [Pg.201]

Another promising issue of electrical studies is the observation made by different groups of workers (30,31,42,43) that the alcohol chain length has a drastic influence upon the conductive behavior of w/o microemulsions using alkaline metal soap/alcohol combinations as surface-active agents. For instance, Shah and co-workers (42,43) reported that water-in-hexadecane systems involving potassium oleate and either 1-hexanol or 1-pentanol ex-... [Pg.202]

Complementary conductance experiments were made with a view to investigate the influence of the cosurfactant upon microemulsion conductive properties. Comparative Type 3 measurements were performed on water-in-hexadecane systems using potassium oleate combined in the 3/5 mass ratio with either 1-pentanol or 1-hexanol. [Pg.213]
