“…a The expanded uncertainties U(w) for 0.95 level of confidence (k = 2) were calculated by considering the standard uncertainties: u(T) = 0.02 K, u(△l) = 7 μm, u(t) = 0.002 μs; for the pressure measurements, three pressure sensors were used with different operating ranges possessing the following u(p) values: 0.002 MPa for p < 10 MPa, 0.02 MPa for p < 100 MPa, and 0.06 MPa for p ≥ 100 MPa. 6for 1-butanol: ○ experiment, this work, ▬ calculated speed of sound by Safarov et al, 15 experimental literature data: × Dávila et al, 29 + Plantier et al, 30 △ Wilson and Bradley, 32 ▽ Carnevale and Litovitz, 33 < Hawley et al, 34 ◇ Shoitov and Otpushchennikov, 39 ◪ Nematulloev et al, 40 ◩ Belinskii et al 41…”

“…7,13,14 Moreover, such data are important to validate speed of sound calculations by means of thermodynamic models. [15][16][17][18] In this work, the pulse-echo technique was implemented to measure speed of sound of methanol, 1-propanol, 2-propanol and 1-butanol. Ethanol was omitted from this series because it was measured extensively in the past.…”

Because of their caloric and thermal nature, speed of sound data are vital for the development of fundamental Helmholtz energy equations of state for fluids. The present work reports such data for methanol, 1-propanol, 2-propanol and 1-butanol along seven isotherms in the temperature range from 220 K to 500 K and a pressure of up to 125 MPa. The overall expanded uncertainty varies between 0.07% and 0.11% with a confidence level of 95%. The employed experiment is based on a double path length pulse-echo method with a single piezoelectric quartz crystal of 8 MHz, which is placed between two reflectors at different pathlengths. Measured speed of sound data for the four alcohols are fitted with double polynomial equations and compared with literature sources.

“…More literature data are available for the high-pressure density of 1-butanol. Recently, Safarov et al [16] reported the experimental density of 1-butanol in the temperature range from (263.15 to 468.15) K and at pressures up to 140 MPa and they provided a careful literature search on experimental high-pressure density reported up to now. They also calculated the high-pressure speed of sound in 1-butanol using pressure dependence of density.…”

1-Butanol can be considered as a good fuel additive, which can be used at high pressures. Therefore, the knowledge of high-pressure thermophysical properties is crucial for this application. In this paper, new experimental data on the speed of sound in 1-butanol in the temperature range from 293 to 318 K and at pressures up to 101 MPa are reported. The speed of sound at a frequency of 2 MHz was measured at atmospheric and high pressures using two measuring sets operating on the principle of the pulse–echo–overlap method. The measurement uncertainties were estimated to be better than ±0.5 m·s−1 and ± 1 m·s−1 at atmospheric and high pressures, respectively. Additionally, the density was measured under atmospheric pressure in the temperature range from 293 to 318 K using a vibrating tube densimeter Anton Paar DMA 5000. Using the experimental results, the density and isobaric and isochoric heat capacities, isentropic and isothermal compressibilities, isobaric thermal expansion, and internal pressure were calculated at temperatures from 293 to 318 K and at pressures up to 100 MPa.
