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...
