摘要: Excess molar enthalpies, H m E , have been determined for propylene carbonate + five linear ketones (2-propanone, 2-butanone, 2-hexanone, 2-octanone, or 2-undecanone) and three cyclic (cyclohexanone, 2-methylcyclohexanone, 2,6-dimethylcyclohexanone) at 298.15 K atmospheric pressure by means of an LKB flow microcalorimeter. Results correlated using the Redlich-Kister equation, adjustable parameters evaluated least-squares analysis. values are found to be positive all mixtures with exception 2-propanone, which shows a sign inversion .
