J. Demetervodnar et al., KINETIC-STUDY OF THE DIFFUSION AND ADSORPTION OF FATTY-ACIDS AT THE BENZENE-WATER INTERFACE, Journal of colloid and interface science, 183(2), 1996, pp. 424-430
Dynamic interfacial tension measurements were used to investigate the
kinetics of the diffusion/adsorption of surfactant molecules at the be
nzene-water interface, Measurements were performed on stearic acid and
capric acid by the pendant drop method at both benzene-acidic aqueous
and benzene-basic aqueous interfaces. The process takes place by diff
erent mechanisms in the acidic and basic aqueous phases, The mechanism
of the interfacial neutralization of stearic acid with sodium hydroxi
de is discussed. (C) 1996 Academic Press, Inc.
