Vapor–liquid equilibria of the binary mixtures 2-butanone+t-pentanol, t-pentanol+butyl acetate and 2-propanol+diethyl ketone at 101.3 kPa

摘要: Abstract Vapor–liquid equilibria have been measured at 101.3 kPa for three binary mixtures of 2-butanone+ t -pentanol, -pentanol+butyl acetate and 2-propanol+diethyl ketone. The isobaric T – x y data reported the thermodynamic consistency has examined. Calculations non-ideality vapor phase made with second virial coefficients determined by Tsonopoulos correlation. Various activity coefficient models used to correlate experimental data. Satisfactory results obtained optimally fitted parameters are presented.
