Solvent Effect of Polyhydric Alcohol on the Biochemical Potential of Iso-amyl Methanoate

The biochemical potential of Iso-amyl methanoate is due to formation of methanoic acid as its solvolysis product. It is best highlighted by studying the kinetics of acid catalysed solvolysis of Iso-amyl methanoate in aquo-Glycerol reaction media having different concentration of Glycerol (trihydric alcohol) from 20-80% (v v) and at different temperatures ranging from 20 to 40°C. The depletion and enhancement observed respectively in iso-composition and iso-dielectric activation energies reveal that the transition state is solvated and initial state is desolvated with addition of Glycerol in reaction media, Almost unity value of the slope of the plots of log k values against log [H+ ] values shows that the reaction follows AAC 2 mechanism. From the values of iso-kinetic temperature, which comes to be 283.0, it may be concluded that in water-Glycerol reaction media, the reaction follows Barclay-Butler rule and there is weak but acceptable interaction between solvent and solute
