Determination of the equilibrium constant for complex formation in a binary mixture of chloroform and triethylamine from viscosity data on the basis of the ideal associated solution model

In a binary mixture of chloroform and triethylamine there exists an equilib rium between chloroform, triethylamine and an 1:1 chloroform-triethylamine complex. The equilibrium constant for the formation of this complex has bee n estimated by analysing the viscosity data of the mixture on the basis of the ideal associated solution model. An excellent agreement is observed bet ween the equilibrium constant obtained from the present analysis and the li terature value obtained from vapour pressure measurements.
