Interfacial transport of salicylic acid

Research output: Contribution to journal › Article › peer-review

Abstract

The transport of salicylic acid across the water-isopropyl myristate interface has been studied. The kinetic barrier for transfer has been measured as a function of temperature and pH using a rotating diffusion cell. It has been shown that the kinetics are independent of the pH for pH values around the pK_a of salicylic acid. From the temperature dependence, thermodynamic parameters have been calculated and a large positive entropy for transfer into the interfacial region is evident.
