SPEED OF SOUND IN n-HEXANE, n-OCTANE, n-DECANE, AND n-HEXADECANE IN THE LIQUID STATE
T. S. Khasanshin, V. S. Samuilov, and A. P. Shchemelev UDC 534.2:547.217.9 This paper describes an improved experimental facility for measuring the speed of sound in liquids with an accuracy of up to 0.1%. Measurements of the speed of sound in liquid n-hexane, n-octane, n-decane, and n-hexadecane at temperatures of 298-433 K and pressures of 0.1-100 MPa have been made. It has been shown that in the possible comparison range the obtained values of the speed of sound are in good agreement with the literature data.
