✦ Synopsis

Rigorous ~-ea~nem ofPTC a kinotics roquires a knowledge of how the system is ~Β£ectod by clmng~ in mlerfacial area generation since this variable sh~q~y affects the rates of the U'easfer step. Here, a simple equation is derived for estimation of interfaeial area geaeratiea in laminar-flow fiquid-liquid systems. While derivatice of this equation did not consider many of the sophisticated and releveat phemomema which affect interfacial area generation, particularly those which occur at higher stirring speeds, the equation is highly useful for ~Β’al simulation of PTC kinetics to determine expected appment reaction rate -stirring rate profiles. The equation also indicates a reciprocal rolationship between interracial tension and the rates of PTC reactions for which the transfer step is rate controlling. Calculation results are shown to be consistent with reported experimental date.

A model based on the two film approximation is proposed for the description of the kinetics of the hydrogen isotope exchange between CHCl3 and DzO. In this model, details of mass transfer in interfacial region between the two liquid phases are considered and the kinetics of the exchange reaction is
