Abstract
The experimental PvTx – data are presented for gas phase, curve of condensation and two-phase region of binary system R218–HFE347mcc with concentrations of second component from 5,0 to 20,6 % (mass). The measurements are carried out by isochoric-related method of subsequent expansions in diapasons of temperatures from 299,15…353,15 K at pressures up to 2,047 MPa. The local equation of state of virial type is elaborated for calculations of thermodynamic properties of system in pointed out region of concentrations and temperatures. The mean square uncertainties of compressibility approximation is 0,209 %.
