Heats Of Mixing

The heats of mixing at 45.00 �C have been measured at intervals over the whole concentration range for the following systems : acetone+benzene, acetone+carbon tetrachloride, aoetone+acetonitrile, acetone+nitromethane, n-propanol+benzene, and n-butanol+benzene. The heats of mixing are discussed in the light of the authors' earlier results for similar systems.

Heats Of Mixing

The heats of mixing at 45.00 �C have been measured at intervals over the whole composition range for the systems : acetonitrile+carbon tetrachloride, acetonitrile+benzene, acetonitrile +nitromethane, nitromethane + carbon tetrachloride, and nitromethane+benzene. These data, together with the excess free energy data of Brown and Smith (1954, 1955a, 1955b), have been used to calculate the excess entropy of mixing for these systems.

Excess Thermodynamic Functions

Values of heats of mixing are reported for methanol, n-butanol, and n-octanol with carbon tetrachloride at 25 °C. The experimental results are combined with data from other sources and an analysis of the excess thermodynamic functions for carbon tetrachloride solutions of methanol, ethanol, n-propanol, n-butanol, and n-octanol in terms of Barker's theory of solutions is described. The behavior of these systems can be reproduced fairly well by the Barker model.

Improved Accuracy

A calorimeter has been designed for measuring the heats of mixing of binary liquid systems, which eliminates the need to correct for changes in the composition of the vapour phase on mixing. Improved accuracy has thus been obtained. Heats of mixing have been measured for the three binary systems formed from the three components carbon tetrachloride, chloroform and methylene chloride, and also for the systems benzene + carbon tetrachloride and benzene + ethylene dichloride. Reports that the last system is ideal have been disproved.

Nuclear Magnetic Resonance Spectra

The dielectric constants of the liquid mixtures piperidine/tetrahydropyran, piperidine/cyclohexane, and tetrahydropyran/cyclohexane have been determined in the temperature range 20 to 60 °C. They have been used to evaluate kirkwood's g -factor for the last two systems, and for the tetrahydropyran/ cyclohexane system, dipoler contributions to the execss thermodynamic functions of mixing . which have also been calculated for the chloro form/carbon tetrachloride system. The heats of mixing of the above systems have been determined (at 20 °C) in order to compare the strengths of the various types of molecular interaction involved. All the mixtures are formed endothermally, suggesting that N — H . . .O hydrogen bonds formed in the first system are weaker than the N — H . . .N bonds solely present in the second, which has the largest excess enthalpy of the three systems. Nuclear magnetic resonance spectra have provided evidence of the formation of these hydrogen bonds.

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.

Heats Of Mixing

The heats of mixing of carbon tetrachloride with diethyl ether, dimethyl sulphide, and pyridine have been measured at 25�. The negative values of HE are interpreted as an indication of strong specific interactions between the donor atoms O, S, N, and the CCl4.

Wide Range

A new calorimeter, suitable for the measurement of heats of mixing as small as 0·1 J resulting from the mixing of not more than 1cm 3 of each component in the absence of any vapour phase and over a wide range of temperatures, is described. It has been used to measure heats of mixing for the pairs of liquids carbon tetrachloride + chloroform, carbon tetrachloride + cyclo hexane, and benzene + solutions of biphenyl in benzene. The results are examined in the light of current theories of solutions.
