• Vapor-liquid equilibrium data have been obtained for systems methanol-methyï acetate, ethanolethyl acetate and n-butanol-n-butyl acetate with calcium chloride at atmospheric pressure. Calcium chloride was added up to the saturated concentration. By adding salt, the increase of relative volatility of acetic ester was observed and the azeotropic composition shifted to the higher acetic ester composition in all systems. The solubilities of calcium chloride in these boiling alcohol-acetic ester solutions were shown in figures. It is suggested that the salt effect of calcium chloride may be utilized effectively for the separation of these alcohol-acetic ester mixtures.
