✦ Synopsis

Excess molar volumes V E m at the temperatures 298.15 K and 308.15 K and normal atmospheric pressure for [x{ClCH2CH2CH2Cl or ClCH2(CH2)2CH2Cl}+(1-x)CH3CO(CH2)q-3CH3] with q=4, 5, and 6 were obtained from measurements of the density with an Anton-Paar densimeter. The V E m values increase as q increases and when ClCH2CH2CH2Cl is replaced by ClCH2(CH2)2CH2Cl. Excess molar volumes decrease when the temperature increases. The trend of the excess volumes with the separation of the Cl atoms of the dichloroalkane is just the opposite to that found in previous papers for the excess enthalpies.

Excess volumes of (1,2-dichloroethane or 1,2-dibromoethane + each of several isomers of butanol) have been determined from density measurements at the temperatures \(298.15 \mathrm{~K}\) and \(313.15 \mathrm{~K}\) using an Anton-Paar dersimeter. The results show that excess volumes are positive over
