摘要：

Thermophysical property data for the binary system of 1-methoxy-2-propanol (PGME) + dimethyl sulfoxide (DMSO), a potential candidate for use as the scrubbing liquid for the absorption of SO2, are lacking in the literature. This paper presents experimental data at 0.1 MPa on the density and viscosity for this binary system measured over the whole composition range at T=(298.15, 303.15, 308.15, 313.15 and 318.15) K. The extended combined uncertainty U-c with a 0.95 level of confidence for the pycnometer method and Ubbelohde viscometer used in this study is 0.002gcm(-3) and 0.028 cm(2)s(-1), respectively. The PGME + DMSO system shows negative values of the excess molar volume at all temperatures and compositions. Based on UV-Vis and FTIR, the intermolecular interaction of PGME with DMSO was confirmed as hydrogen bonding between the hydroxyl hydrogen atom in PGME and the oxygen atom in DMSO.
