摘要：

The speeds of sound in pentan-1-ol, 2-methyl-2-butanol, and cyclopentanol were measured within the temperatures from T = (293 to 318) K and at pressures up to 101 MPa. The densities have been measured in the same temperature range under atmospheric pressure. The densities, isobaric heat capacities, isobaric thermal expansions, and isentropic and isothermal compressibilities as functions of temperature and pressure were calculated using the speeds of sound under elevated pressures together with the densities and heat capacities at atmospheric pressure. The effects of temperature and pressure on the isobaric heat capacity, isobaric thermal expansion, and isothermal compressibility of pentan-1-ol, 2-methyl-2-butanol, and cyclopentanol are compared and discussed.
