The polarization of chemical reactions

Microwaves have been widely used in organic chemical syntheses, but the mechanism is still unclear. The aim of this paper is to study the polarization of polar molecule reactions in the liquid phase. A novel model is proposed to describe the polarization of chemical reactions. In this model, the polarization is expressed by the summation of the orientational polarization of the liquid mixture and the polarization increment due to the chemical process. On the basis of the assumption of local equilibrium, the chemical process is divided into a series of equilibrium systems. We derive the general expression for the polarization increment according to the mass balance equations. By considering a simple chemical process, we give a specific expression for the polarization.
