Abstract: | The speeds of sound in 2-methyl-1-butanol were measured at temperatures from 293K to 318K and pressures up to 101MPa. The
densities were measured in the same temperature range under atmospheric pressure. The isobaric specific heat capacities were
measured at atmospheric pressure and temperatures from 284K to 355K. The densities, isobaric heat capacities, isobaric thermal
expansions, isentropic compressibilities, isothermal compressibilities, and internal pressures as functions of temperature
and pressure were calculated using the experimental 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 thermal expansion and internal
pressure of 2-methyl-1-butanol are discussed and compared with those of pentan-1-ol, 2-methyl-2-butanol, and pentan-3-ol. |
