Volumetric properties and viscosities of the ternary system methyl butanoate + n-heptane + 1-chlorooctane and its binary constituents in the temperature range from 283.15 to 313.15 K

Abstract

The densities, kinematic viscosities and other derived properties of the binary systems n-heptane+1-chlorooctane and methyl butanoate+1-chlorooctane were determined at 283.15, 293.15, 303.15 and 313.15 K and atmospheric pressure for the whole composition range. Moreover, similar properties were determined for the ternary system methyl butanoate+n-heptane+1-chlorooctane at 283.15 and 313.15 K. The volumetric properties obtained for both binary and ternary systems were compared to those predicted by the model proposed by Nitta et al. using structural and energetic parameter sets available in the literature. Viscosities for both kind of systems were correlated to composition by means of several specific equations, for comparison. Kinematic viscosities were also compared with those predicted by two group contribution models (UNIVAC and UNIFAC-VISCO). Finally, several equations for predicting the ternary properties only from its binary constituents results were applied.
