ABSTRACT

In this experimental investigation, the bubble points of three binary mixtures consisting of propyleneoxide + ethyl benzene, propylene oxide + 2-methylpentane, and propylene oxide + 2-methyl-1-pentenewere determined. The method of experimentation was the synthetic method in which phase change for amixture of constant overall composition is observed visually by varying pressure at constant temperature.Each binary system was measured for a range of concentrations. Temperatures and pressures also varied from 323 K to 373 K and up to 5 bar, respectively. It is observed that the solubility of propylene oxide varies,in increasing order, in 2-methylpentane, 2-methyl-1-pentene, and ethyl benzene, with the solubilitybeing far greater in ethyl benzene compared to either 2-methylpentane or 2-methyl-1-pentene.
