In the present study, an accurate experimental information for the widely used commercial refrigerating compressor oils ONF 46, ACD 100 FY, Azmol, FR 32, XC 15, XC 40 and WF 15A is presented. Experimental data on the capillary constant, surface tension, density, refractive index and kinematic viscosity at the temperature range from 293 to 353 K for seven commercial compressor oils are reported. In addition, the experimental data on the isobaric heat capacity at temperature range from 288 to 393 K, the vapor pressure at liquid-saturated curve and average molecular weight for four commercial compressor oils are fi rstly presented in the paper. The data obtained are fi tted by few-constant correlations. Based on results obtained, the values of pseudocritical temperature for the compressor oils have been determined.
