Surface tensions were measured for the ten binary liquid systems: cyclopentane + carbon tetrachloride, cyclopentane + tetrachloroethylene, cyclopentane + benzene, cyclopentane + toluene, cyclohexane + tetrachloroethylene, cyclohexane + benzene, cyclohexane + toluene, cyclohexane + cis-decalin, cyclohexane + trans-decalin, and benzene + o-xylene. The system cyclohexane + benzene was studied at 20 and 30 °C. Measurements for the other nine systems were carried out at 25 °C. The principle of corresponding states was used to correlate the surface tension results with other properties of the pure component liquids and of their binary mixtures.

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.

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.

Gibb’S Free Energy

The density (), viscosity (), and surface tension () of binary mixtures of carboxylic acids (CAs) (ethanoic acid (EA), propanoic acid (PA), butanoic acid (BA)) + benzene (BEN) or acetophenone (ACT) have been measured at 298.15, 308.15, and 318.15 K. From the experimental results, excess values of molar volume (), viscosity (), Gibb's free energy for the activation of low (), and surface tension () were evaluated and fitted to a Redlich-Kister type of equation. The parameter “” of Grunberg and Nissan expression has also been calculated. From the sign and magnitude of , , , , and “” values, it is concluded that specific interactions are present in CA+ACT system and these interactions are absent in CA + BEN mixtures. Various viscosity and surface tension models have been used to test the consistency of the data.

Densities and sound velocities of the binary liquid mixtures of sulfolane + aniline, sulfolane + N,N-dimethylaniline, sulfolane + N,N-diethylaniline over the whole range of composition and their pure component were measured at temperatures (T = 303.15, 308.15, 313.15 K) and atmospheric pressure. A high precision vibrating-tube densitometer was used for the measurements. From the measured values, excess adiabatic compressibility (βs E), excess sound velocity (uE), excess internal pressure (Pi E) and deviation of surface tension (Δγ) were calculated for each of the systems. The excess properties and surface tension deviation were fitted to the Redlich-Kister equation. All these properties have been discussed in terms of molecular interactions.

Viscosities (η, N s m-2) and surface tensions (γ, N m-1) of methanol, ethanol, glycerol, ethyl acetate, n-hexane, diethyl ether, chloroform, benzene, carbon tetrachloride ( CCl 4), tetrahydrofuran (THF), dimethylformamide (DMF), dimethylsulfoxide (DMSO), acetonitrile, and formic acid have been measured with survismeter and compared with the data obtained by Ubbehold viscometer and stalagmometer, respectively. The ±1.1 × 10-5 N s m -2 and ±1.3 × 10-6 N m -1 deviations are noted in the data, in fact literature data of surface tension and viscosity are available to 2nd and 3rd place of decimals, respectively, while the survismeter measures them to 3rd and 4th place of decimals, respectively. The survismeter is 2-in-1 for viscosity and surface tension measurements together with high accuracies several times better than those of the separately measured data. Viscosities and surface tensions of aqueous DMSO, THF, DMF, and acetonitrile from 0.01 to 0.20 mol kg-1 and mannitol from 0.005 to 0.02 mol kg-1 have been measured with survismeter with ±1.2 × 10-5 N s m -2 and ±1.3 × 10-6 N m -1 deviations, respectively. The data are used for friccohesity and dipole moment determination, the lower viscosities, surface tension, and friccohesity values are noted for mannitol as compared to DMSO, THF, DMF, and acetonitrile solutions. The weaker molecular interactions are noted for mannitol. As compared to viscometer and stalagmometer individually, it is inexpensive and minimizes 2/3rd of consumables, human efforts, and infrastructure with 10 times better accuracies.
