电场对相间传质和相分散具有强化作用。为了探究电场强化酯交换反应的作用机理,基于电场作用下碱催化醇油酯交换反应动力学的分析,采用显微高速摄像技术对NaOH作为催化剂的酯交换反应体系中液滴的荷电分散行为及演变过程进行了可视化研究,精确捕捉了不同电场强度下液滴在连续相中荷电破碎的显微形貌特性.结果表明随外加电场强度的增加,液滴在连续相中的荷电破碎速率加快,液滴尺寸显著下降,有利于酯交换反应的强化. The electric field has the strengthening effect on the interphase mass transfer and the phase dispersion. In order to explore the action mechanism of electric field enhanced transesterification reaction, based on the analysis of alkali catalyzed transesterification kinetics of methanol oil under electric field, the charge-dispersion behavior of droplets in transesterification reaction system with NaOH as catalyst And the evolution of the droplet in the continuous phase were studied.The results show that with the increase of the applied electric field strength, the charge drop of the droplet in the continuous phase Accelerated rate of droplet size decreased significantly, is conducive to strengthening the transesterification reaction.
