OPTICAL INVESTIGATION OF ABSORPTION AND SURFACE CONDENSATION OF VAPORS NEAR SATURATION,

Abstract

The thickness of an absorbed layer of liquid was measured by elliptical polarization of light reflected under a oblique angle and was analyzed with the aid of a polarization microscope. The adsorption of alcohols, water, carbon tetrachloride, and benzene was shown on graphs plotting thickness versus the ratio of the relative pressures. For polar substances, the graph for isotherm adsorption on glass intersects the saturation ordinate. For nonpolar substances the isotherm asymptotically tends toward the ordinabe. The existence of a break in the continuity of vapor condensation of polar liquids is explained by the structural characteristics of the boundary phase. (Author)
