The density and viscosity were measured in the temperature range of (273.15 to 333.15) K at atmospheric pressure, and the vapor pressure was measured at temperatures from (293.59 to 400.80) K for 1,1,1-trifluoro-2,3-dichloropropane. The expanded uncertainties in temperature, density, viscosity, and pressure measurements were estimated to be less than 20 mK, 0.0005 g.cm(-3), 0.006 mPa.s and 1.2 kPa, respectively. A total of 31 density experimental points were obtained with 31 viscosity experimental points and 58 vapor pressure experimental points. Temperature-dependence correlation equations for the density, viscosity, and vapor pressure were proposed.
