“…As is well known [2,[18][19][20][21] mixed monolayer studies provide information on the miscibility and the nature of interaction between the component molecules. If at a given pressure, the component molecules of a binary mixture do not occupy the same area as they do in their individual monolayers, i.e.…”

The pressure-area characteristics of the monolayers of butyl p-( p-ethoxyphenoxycarbonyl) phenyl carbonate (BPC) have been studied at various temperatures in the range 10°-310C. With compression, the film passes from the gaseous (G) to the multilayer (M) state, via the liquid condensed (L) state. The transitions from G to L and L to M states occur over wide plateau regions at lower temperatures. The widths of these regions and also the molecular areas at which they begin decrease linearly with elevation in temperature. A remarkable feature of the isotherms is that, in the G and L regions, as the temperature is lowered, they shift in the direction of higher pressure. This is explained by taking into account the possible molecular orientations with respect to the substrate. The overall surface behaviour of BPC differs from that of some other phenyl benzoates studied earlier. In particular, BPC does not form liquid-crystal-like multilayers. The paper also includes certain results on the surface behaviour of mixtures of BPC and cholesterol; the condensing effect of cholesterol is briefly discussed.
