Abstract  

Heats of mixing HE at 303.15 K and 1.013 bar are reported for two ternary liquid mixtures piperidine(1)+n-heptane(2)+cyclohexane(3) and piperidine(1)+n-octane(2)+cyclohexane(3). A Redlich-Kister type smoothing equation was used to represent and correlate the results. A dispersive quasichemical (DISQUAC) theoretical model was used for predicting the heats of mixing HE at 303.15 K and 1.013 bar for these two ternary liquid mixtures.

Abstract  

Experimental heats of mixing Δmix H at 303.15 K and normal atmospheric pressure were obtained for the binary mixtures cyclohexanone+(1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2-trichloroethane,1,1,2,2-tetrachloroethane or pentachloroethane), using a Calvet microcalorimeter. The Δmix H values for all the mixtures were negative, indicated that important interaction occur between the ketoxy group and chloroalcane.
