Ultrasonic speeds of 4-aminobutyric acid in 0.0041,0.0125 and 0.0207 mol·kg-1 aqueous salbutamol sulphate(SBS) solutions are measured at 308.15,313.15 and 318.15 K.Isentropic compressibility kS,change in isentropic compressibility△k S,relative change in isentropic compressibility( 0 S S △k /k) ,apparent molal compressibility kφ,limiting apparent molal compressibility k0 φ,transfer limiting apparent molal compressibility k0 φ,hydration number nH,pair and triplet interaction parameters kAS,kASS are estimated.The above parameters are used to interpret the solute-solute and solute-solvent interactions of 4-aminobutyric acid in the aqueous salbutamol sulphate solutions.
Ultrasonic speeds of 4-aminobutyric acid in 0.0041, 0.0125 and 0.0207 mol · kg-1 aqueous salbutamol sulphate (SBS) solutions are measured at 308.15, 313.15 and 318.15 K. Vissentropic compressibility kS, change in isentropic compressibility Δk S, relative change in in isentropic compressibility (0 SS Δk / k), apparent molal compressibility kφ, limiting apparent molal compressibility k0 φ, transfer limiting apparent molal compressibility k0 φ, hydration number nH, pair and triplet interaction parameters kAS, kASS are estimated. above parameters are used to interpret the solute-solute and solute-solvent interactions of 4-aminobutyric acid in the aqueous salbutamol sulphate solutions.
