摘要：
Values of experimental density of difluoromethane (R32) and five compositions of {R32 + trans-1,3,3,3-tetrafluoropropene (R1234ze(E))} binary mixtures are reported over the temperature range from 283 K to 363 K and at pressures up to 100 MPa with a vibrating-tube densimeter. The excess molar volumes were calculated from experimental results and fitted to the Redlich-Kister equation. The maximum standard deviation and average standard deviations of the experimental and calculated values of excess molar volume from Redlich-Kister equation are 0.07789 cm(3).mol(-1) and 0.01645 cm(3).mol(-1), respectively.
