Excess molar volumes V E m for methyl tert-butyl ether-benzene at 293 15K?298 15K?303 15K?308 15K?313 15K?318 15K and methyl tert-butyl ether-methylcyclohexane at 293 15K?298 15K?303 15K?313 15K have been calculationed from densities measured with a specific gravity balance.

The excess molar volumes V~E of {trichloromethane +1,3,5_trimethylbenzene,trichloromethane + 1,2,4_trimethylbenzene,nitrobenzene + 1,3,5_trimethylbenzene,nitrobenzene + 1,2,4_trimethylbenzene} were determined in the whole range of composition using a vibrating_tube densimeter at 298\^15 K.

The excess molar volumes of {1,8-cineole+CCl 4, +CHCl 3} were determined as a function of mole fraction x using a vibrating-tube densimeter at the temperatures 298 15 and 308 15K All mixtures exhibit negative values over the entire composition range at both temperatures.
