The presentresearch work gives investigation on the effect of temperature variation on the thermodynamic and transport properties of binary system involving 18-crown-6 ether and alkali metal salts. The binary liquid system (18-crown-6 + one millimole of alkali metal salts) were investigated at 298.15 K and 308.15K. Thermodynamic parameters such as adiabatic compressibility (Ks), free length (Lf) and acoustic impedance (Z)were calculated and used to understand the complexation and the interaction in between 18-crown-6 and alkali metal ions.In this binary systems of 18-crown-6 ether formed a strong complexation with alkali metal ions as the following order - KBr > KCl > NaBr > NaCl> LiBr > LiCl.

18-crown-6, alkali metal salts, binary system, interaction, and complexation.
