ABSTRACT

Isobaric vapor-liquid equilibrium data at 101.325 kPa have been determined for the binary systems 3-methyl-1-butanol + 3-methyl-1-butyl ethanoate and 1-pentanol + pentyl ethanoate. The data were obtained using a vapor recirculating-type equilibrium still. Vapor pressures of 3-methyl-1-butanol and 3-methyl-1-butyl ethanoate were measured in a Swiestoslawski apparatus. Calculations of the nonideality of the vapor phase were made with the second virial coefficients evaluated from the Hayden-O Connell method. The activity coefficients and boiling points of the solutions were well-correlated with the mole fraction using the Wilson, nonrandom two-liquid (NRTL), and universal quasichemical activity coefficient (UNIQUAC) equations. The mixtures do not present an azeotrope.
