The ultrasonic speeds, u, in the liquid phase of 1,1-dichloro-1-fluoroethane, CCl[sub 2]FCH[sub 3], were measured along 11 isotherms from 283 to 373.15 K and from 0.1 MPa or near the vapor pressure to about 50 MPa. The measurements were carried out by a sing-around technique operated at a frequency of 2 MHz with an uncertainty of less than [plus minus]0.2%. The ultrasonic speeds and related thermodynamic properties for CCl[sub 2]FCH[sub 3] appear to have characteristics different from those for CCl[sub 3]F and CHCl[sub 2]CF[sub 3] reported elsewhere.
