Lower critical solution coexistence curve and physical properties (density, viscosity, surface tension, and interfacial tension) of 2,6-lutidine + water

Abstract

The coexistence curve and physical property data (densities, viscosities, surface tensions, and interfacial tensions of the equilibrated coexisting phases) for 2,6-lutidine+water have been determined over the range 34-60 o C, and the density and viscosity differences calculated. The compositions were determined through the refractive index at 22 o C, densities by a commercial electronic oscillating U-tube, viscosities by a U-tube viscometer, surface tensions by a du Nouy ring method, and interfacial tensions by a spinning drop interfacial tensiometer
