Dynamics of “Micellar Autocatalysis”

Phase-Transfer Model

Biphasic alkaline hydrolysis of ethyl caprylate (EC)

(a) time evolution of EC

(total volume of overlayed organic phase in L)

(b) time evolution of C

(total concentration in aqueous phase in mol L^-1)

Points are experimental data. The line represents a fitting by the kinetic model shown below.
