摘要：

Isothermal vapour-liquid equilibrium data for the difluoromethane (R32)-1,1,1,2,3,3,3-Heptafluoropropane (R227ea) binary system are presented at 283.20, 303.21, 323.21 and 343.38 K and pressures up to 4.5 MPa. The experimental method, used for this work, is of the static-analytic type. It takes advantage of mobile pneumatic capillary samplers (Rolsi(TM), Armines' patent) developed in our laboratory. The four P, x, y isothermal data have been represented with the Soave-Redlich-Kwong (SRK) equation of state and the MHV1 rules involving the NRTL model. (C) 2003 Elsevier Science Ltd and IIR.
