“…Subsequently, the (P, V m , T, and x) measurements of (benzene + 1,3,5-trimethylbenzene) at temperatures from 298.15 K to 328.15 K and at pressures up to 40 MPa [2] were carried out. Next works reports the density measurements on (acetophenone + benzene, or toluene, or 1,3-xylene, or 1,3,5-trimethylbenzene) [3], and (propiophenone + benzene, or toluene, or ethylbenzene, or butylbenzene) [4] at two temperatures (298.15 K and 328.15 K) at atmospheric pressure and the high-pressure (P, V m , T, and x) measurements on (toluene + propiophenone) [5]. In this communication we are reporting the detailed temperature dependence of excess volumes of (toluene + propiophenone) with the aim of determining the density and excess volume data below the propiophenone melting temperature.…”
