The excess molar enthalpies for (ethanediol, or 1,2-propanediol, or 1,2-butanediol + water) have been measured at five different temperatures over the whole composition range in an LKB flow microcalorimeter. A flow-mix cell has been developed and used for the measurements. All the mixtures exhibit n
Measurement of densities and excess molar volumes for (1,2-ethanediol, or 1,2-propanediol, or 1,2-butanediol + water) at the temperatures (278.15, 288.15, 298.15, 308.15, and 318.15) K and for (2,3-butanediol + water) at the temperatures (308.15, 313.15, and 318.15) K
Excess molar volumes V E m of (1,2-propanediol + water) and (1,2-butanediol + water) were measured at temperatures of (288.15, 298.15, and 308.15) K and at pressures of (0.1, 20, 40, and 60) MPa with a densimeter, model DMA 512p from Anton Paar. Values of V E m were negative for all the mixtures stu
