ABSTRACT

Isothermal VLE data of 2-propanol+n-hexane system were measured at near critical temperatures to be compared with similar data for the ethanol+n-hexane and methanol+n-hexane systems. The critical pressure was determined from the critical opalescence of the mixtures. A circulating type apparatus with a view cell was used. These mixtures are highly non-ideal due to the association of the alcohol. The data could be correlated with sufficient accuracy by using the Peng-Robinson-Stryjek-Vera(PRSV) equation of state with Wong-Sandler mixing rules.
