Heats of Mixing for Binary Mixtures. The Energy of Hydrogen Bonding between Alcohol and Ketone Molecules

Abstract
A microcalorimeter of the twin type has been constructed, one which is operated semiautomatically. Using this apparatus, the heats of mixing for alcohol-ketone, alcohol-hexane, and ketone-hexane solutions have been measured. From these heats of mixing, the hydrogen bond energy of the O–H…O= type has been estimated to be about 4kcal. by means of the thermochemical cycle.
