Zusammenfassung

Excess molar enthalpies (H**E) of 1,2-Dichloroethane plus n-Hexane, plus n-Hexadecane, plus Cyclohexane, plus Benzene, plus Tetrachloromethane, and plus 1,2-Dibromoethane, at 288. 15, 298. 15, 308. 15, and 318. 15 K, and densities of the pure components at 298. 15 K, were measured. The most relevant point about the results obtained is the sluggishness of H**E to change with temperature. To explain this effect, a correlation between interaction potential energy and intramolecular potential energy in the conformational equilibrium should be taken into account.
