ABSTRACT

Excess enthalpies at T = (298.15 and 308.15) K have been measured for liquid (1-methyl-2-pyrrolidone + 1-chlorobutane, or +1-chlorohexane, or +1-chlorooctane, or +1,2-dichloroethane, or +1,4-dichlorobutane, or +1,6-dichlorohexane) and isothermal (vapor + liquid) equilibria (VLE) at T = (313.15, 323.15, and 333.15) K are reported for (1-methyl-2-pyrrolidone + 1-chlorobutane, or +1-chlorohexane, or +1,2-dichloroethane). The VLE data were reduced using the Redlich Kister equation taking into consideration the vapour-phase imperfection in terms of 2nd molar virial coefficients.
