FREEZING PRESSURES, P, V, T, AND SELF-DIFFUSION DATA AT 298-K AND 313-K AND PRESSURES UP TO 300 MPA FOR 1,3,5-TRIMETHYLBENZENE

Mesurements are reported for the melting point of 1,3,5-trimethylbenzene at pressures up to 345 MPa. Self-diffusion coefficients and p, V, T data have been obtained at 298 and 313 K for pressures up to 280 MPa. Isothermal compressibilities have been calculated from the p, V, T results. The freezing pressures at 0.1 MPa correspond to previously reported values for modification III of trimethylbenzene. Equivalent hard-sphere diameters estimated from the melting point and p, V, T data are used to apply the rough hard-spheres theory to the self-diffusion data; the calculations indicate that there is random packing of the particles. © 1987 Plenum Publishing Corporation.
