Abstract The ultrasonic speed u of [(1 -ϰ) CHClF2(1) + ϰC2ClF5(1)] including the azeotropic mixture [CHClF2(1) + C2ClF5(1)] was measured at pressures up to 51 MPa within the temperature range 283.15 to 373.15 K, using a sing-around technique operated at a frequency of 2 MHz with an estimated uncertainty of less that ±2.4 m·s−1. For ϰ = 0.1537 and 0.6268, measurements of the vapor pressure are also reported.
