Physical Properties (Density, Viscosity, Surface Tension, Interfacial Tension, and Contact Angle) of the System Isopropyl Alcohol + Cyclohexene + Water

Abstract

The equilibrium physical property data (densities, viscosities, refractive index, interfacial tensions, and contact angles) for the liquid−liquid system isopropyl alcohol + cyclohexene + water have been determined at 294 K. The phase diagram and equilibrium tie lines were evaluated. The compositions of the coexistence curve were determined through the refractive index, densities were determined by an electronic oscillating U-tube densitometer, viscosities were determined by a U-tube viscometer, surface/interfacial tensions were determined by a du Nouy ring and a spinning drop method, and contact angles were determined with a goniometer contact angle meter.
