Acoustic nonlinearity parameter B/A determined by means of thermodynamic method under elevated pressures for alkanediols
چکیده انگلیسی


• Pressure–temperature dependence of the B/A nonlinearity parameter.
• B/A decreasing with the pressure increasing.
• Striking differences between α,ω-diols and 1,2-diols.
• The lack of the close relationship between B/A and internal pressure.

The so-called Beyer nonlinearity parameter B/A is calculated for 1,2- and 1,3-propanediol, 1,2-, 1,3-, and 1,4-butanediol, as well as 2-methyl-2,4-pentanediol by means of a thermodynamic method. The calculations are made for temperatures from (293.15 to 318.15) K and pressures up to 100 MPa. The decrease in B/A values with the increasing pressure is observed. In the case of 1,3-butanediol, the results are compared with corresponding literature data. The consistency is very satisfactory. A simple relationship between the internal pressure and B/A nonlinearity parameter has also been studied.
