ABSTRACT
The speed of sound in 2-methyl-2,4-pentanediol has been measured in the temperature range from (293.15 to 318.15) K at pressures up to 101 MPa by the pulse-overlap method. The speed of sound at atmospheric pressure has been measured in the temperature range from (283.15 to 323.15) K by means of the same method. The density has been measured in the temperature range from (278.15 to 358.15) K under atmospheric pressure with a vibrating tube densimeter. The isobaric heat capacity has been measured in the temperature range from (284 to 358) K under atmospheric pressure with a differential scanning calorimeter. The experimental results have been used to calculate densities, isobaric heat capacities, the isobaric coefficient of thermal expansion, and isentropic and isothermal compressibilities in function of temperature and pressure; the effects of pressure and temperature have been discussed.
