    • Abstract

       

      Enthalpies of complex formation (ΔHc) of dibutyl and tributyl amines with the four isomeric butanols were determined at 30°C. The present data were compared with the previous data on isomeric butanols with monobutyl amine complexes. The ΔHc in the case ofn-alcohol has been found to decrease by about 4·0±0·4 kJ/mole on replacement of each hydrogen atom of the NH2 group. The branching of the butyl chain, also, decreases the strength of the complex due to steric hindrance.
