A Micrometer Syringe Dilatometer: Application to the Measurement of the Excess Volumes of some Ethylbenzene Systems at 298.15 K

Abstract

A dilatometer using a micrometer syringe to measure small changes in volume at constant pressure is described. Excess volumes determined for cyclohexane + benzene at 298.15 K are in reasonable agreement with values from the literature. Results are also reported for the excess volumes of mixtures of ethylbenzene with benzene, toluene, and the isomeric xylenes.
