Alkaline Hydrolysis of Esters across the Heterogeneous Liquid-Liquid Interface

초록

Ethyl acetate와 n-butyl acetate의 25℃에서 알카리 가수분해 반응을 개량된 Lewis cell에서 행하여 화학반응을 수반한 물질전달 속도를 측정하였다. 측정한 물질전달 속도는 교반조의 교반속도에 무관하였고 이온강도 증가에 따라 감소하였으나 화학반응촉진 계수는 일정하였다. 측정한 화학반응 촉진계수를 경막설로부터 얻은 용질의 확산방정식의 근사해로부터 해석하여 ester의 알카리 가수분해반응의 2차 비가역 반응속도 정수를 얻을 수 있었으며, 그 값은 ethyl acetate의 경우 0.041 m³/kgmol·s, n-butyl acetate의 경우 0.338m³/kgmol·s 이었다.

The rates of mass transfer with the alkaline hydrolysis of ethyl acetate and n-butyl acetate were measured by using a modified Lewis cell. The rates of mass transfer with chemical reaction were independent of the speed of agitation, and the reaction enhancement factors were independent of the ionic strength. The second order reaction rate constants of ethyl acetate and n-butyl acetate could be obtained from an approximate solution of a diffusion equation by film theory, and their values were 0.041 m³/kg mol·s and 0.338 m³/kgmol·s, respectively.
