Vapour–liquid equilibria in binary and ternary systems composed of 2, 3-dimethylbutane, diisopropyl ether, and 3-methyl-2-butanone at 313.15, 323.15 and 313.15 K

This article reports vapour–liquid equilibrium data in three binary systems, namely 2, 3-dimethylbutane + diisopropyl ether, 2, 3-dimethylbutane + 3-methyl-2-butanone, and diisopropyl ether + 3-methyl-2-butanone and in one ternary system, 2, 3-dimethylbutane + diisopropyl ether + 3-methyl-2-butanone. The data were measured isothermally at 313.15, 323.15, and 333.15 K covering the pressure range of 13 to 108 kPa. The binary vapour–liquid equilibrium data were correlated using the Wilson and NRTL equations by means of a robust algorithm for processing all isotherms together. The resulting parameters were then used to calculate phase behaviour in the ternary system and to comparison the calculated with experimental data.
