Speed of sound on the saturation line for some monohydric aliphatic alcohols

Speeds of Sound, Densities, and Isentropic Compressibilities of 1-Iodohexane at Temperatures from (293.15 to 413.15) K and Pressures up to 200 MPa

“…11 This method allows us to measure the speed of sound and density of a liquid at pressures up to 600 MPa in the temperature range from (223.15 to 523.15) K. The density was measured by an acoustic piezometer with an uncertainty of (0.3%. The density at atmospheric pressure P 0 was measured with an Ostwald-Sprengel-type pycnometer with a capacity of approximately 50 cm 3 . The uncertainty of the density measurements at atmospheric pressure was estimated to be (3 × 10 -5 g‚cm -3 .…”

“…In recent years, interest in measuring the speed of sound in organic liquids has considerably increased. 1,2 In contrast to the n-alkanes, which have been studied by tje acoustic method in a singlephase area, [3][4][5][6][7][8] their halogen-substituted analogues are less well understood.…”

Speed of Sound of Hexane + 1-Chlorohexane, Hexane + 1-Iodohexane, and 1-Chlorohexane + 1-Iodohexane at Saturation Condition

“…All molar quantities are based on the IUPAC relative atomic mass table (IUPAC, 1986). The ultrasonic speed was measured along the saturation line with a pulsephase echo ultrasonic device constructed by the authors, 8 to a precision of (1 m‚s -1 . A block diagram of the equipment is shown in Figure 1.…”

Speeds of Sound, Densities, and Isentropic Compressibilities of 1-Chlorohexane at Temperatures from (293.15 to 413.15) K and Pressures up to 200 MPa

“…The knowledge of thermophysical properties of organic liquids at high temperatures and pressures is the particular importance for chemical technology. In recent years the interest to measurement of the sound speed in organic liquids has considerably increased. , In contrast to the n -alkanes, which have been studied by acoustic method in single-phase area, − acoustic properties of their halogen-substituted analogues are less well understood . This could relate to the high chemical activity and relative thermal instability of certain haloalkanes.…”
