ABSTRACT

Excess molar enthalpies were measured for the binary systems 2-methyl-2-propanol + 2,4,4-trimethyl- 1-pentene at 300 K and for 2-butanol + 2,4,4-trimethyl-1-pentene at 298 K. Vapor-liquid equilibria were also measured for the same systems at atmospheric pressure with a circulation still, and the liquid and condensed vapor phase samples were analyzed with a gas chromatograph. The experimental data were correlated with a Wilson activity coefficient model. Experimental results and the fitted model were also compared with the predictive activity coefficient model UNIFAC (Dortmund).
