Thermodynamic properties of aqueous solutions of some amino acids, glycine and l-alanine with a novel ionic liquid containing salicylate anion, 1-butyl-3-methylimidazolium salicylate, [BMIM][SAL] as an active pharmaceutical ingredient ionic liquid (API-IL) have been investigated by volumetric, ultrasonic, refractometric and viscometric properties at T=(288.15–318.15K). The standard partial molar volume Vϕ0, partial molar volume of transfer ΔtraVφ0, Hepler’s constant (∂2Vϕ0/∂T2)p and apparent molar isentropic compressibility κφ have been calculated from density and speed of sound data. Viscosity and refractive index data were used for determination of viscosity B-coefficients (B), hydration number nH and molar refraction RD parameters. These parameters are helpful to study the structure promoting and solvation behaviour of the API-IL and various interactions present in the ternary solutions of (amino acid+[BMIM][SAL]+water).
