Abstract

The interaction between anhydrous MgCl2 and ethyl benzoate (EB) involves a two-step exothermic process. The thermal effect indicates a rapid first stage attributed to the adsorption of EB on the surface of MgCl2 followed by a considerably slower second stage of the complex formation. The amount of EB bonded in the complex increases with increase in the molar ratio of EB to MgCl2, temperature, and reaction time. During the thermal decomposition of this system, up to its boiling point unreacted or adsorbed EB escapes, then decomposition of the complex takes place resulting in evaporation of the bonded EB. The reaction between EB and MgCl2 is accompanied by a dilation.
