Excess Thermodynamic Quantities

A simple calorimeter has been devised by means of which the heats of mixing (molar excess heats) of the following systems have been determined at 22 °C: acetone – acetic anhydride; acetone – carbon disulfide; acetic anhydride – carbon disulfide; and a pseudo-binary section of the ternary system acetone – acetic anhydride – carbon disulfide. From these data the partial molar excess heats have been obtained. All systems are very non-ideal except the system acetone – acetic anhydride, which is almost ideal.For the partially miscible system acetic anhydride – carbon disulfide, the excess thermodynamic quantities of mixing, GE, HE, and TSE, have been calculated,

Composition Curve

Heats-of-mixing for the liquid system nitrogen/ethane have been measured at 92.3 K and 0.6309 MPa using a cryogenic flow calorimeter. The heat-of-mixing versus composition curve shows that the system is only partially miscible; the compositions between which liquid–liquid separation occurs have been estimated.

The physical properties mentioned in the title have been determined for the six systems: (a) aniline–hexane, (b) methanol–cyclohexane, (c) methanol–carbon disulfide, (d) acetic anhydride–carbon disulfide, (e) acetic anhydride–cyclohexane, and (f) triethylamine–water, over the complete range of composition. All six systems are partially miscible, above or below a critical solution temperature (c.s.t.).From the experimental data, the partial molal heats of mixing have been calculated, using the Redlich and Kister equations. The enthalpy of hydrogen bonding in the triethylamine–water compound appears to be about −1.33 kcal per hydrogen bond.The orientation polarization, according to the Syrkin formula, appears always to exhibit negative deviation from ideality, at least over part of the concentration range.
