Basic acoustic parameters of organic solvents used in ultrasonic cleaning

Sound velocities have been measured and the specific acoustic impedance calculated for the following solvents used in the process of ultrasonic cleaning (commercial technical products): trichloroethylene, tetrachloroethylene, 1,1,1-trichloroethane (Baltane), triehlorotrifluoroethane (Freon TF) and dibromotetrafluoroethane, known as freon 114B2.
