Heats of mixing of Alcohol solutions

Abstract

A calorimeter for the measurement of the heats of mixing of binary liquid systems at temperatures from 20 to 45 °C is described. Heats of mixing have been measured for approximately equimolar mixtures of benzene+carbon tetrachloride at 25 °C, benzene+ethylene dichloride at 25 °C, acetone+chloroform at 25 °C, and ethanol+-carbon tetrachloride at 45 °C. Measurements have been made at intervals over the whole composition range of the systems ethanol+2,2,4-trimethylpentane at 25 °C and ethanol+benzene at 45 °C.
