A calorimeter of twin design with auxiliary apparatus was built for measuring the heat of mixing with a maximum error of ± 1.0%. Reliability of the apparatus was tested with the benzene-methanol system and gave results comparable to those of other investigators with apparatus of different design.

The heat of mixing of diacetone alcohol and water was measured at 25°C over the entire concentration range. A peak value of 238 cal/mole solution was obtained at 0.67 mole fraction water the mixing of two moles water with one of diacetone alcohol.

Specific heat of diacetone alcohol-water mixtures was also measured at 25°C with the same apparatus.
