Vapour-x2013;liquid equilibrium data for the difluoromethane+1,1,1,2,3,3,3-heptafluoro-propane system at temperatures from 283.20 to 343.38 K and pressures up to 4.5 MPa

Abstract

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 Kand pressures up to 4.5 MPa. Theexperimental method, used for this work, is of the static analytic type. It takes advantage of mobile pneumatic capillarysamplers (RolsiTM, Armines' patent) developed in our laboratory. The four P, x, y isothermal data have been representedwith the Soave-Redlich-Kwong (SRK) equation of state and the MHV1 rules involving the NRTL model.
