Abstract

The effect of different composition of a water-Ehtylene glycol solvent on kinetics of amyl methanoate formate was studied at different temperature ranging from 20 to 40°C.The rate constant decreased with increase of water fraction in the solvent from 20 to 80%.The considerably change was found in activation parameters enthalpy of activation (AH*) and entropy of activation (AS*) and free energy of activation free energy of activation (AG*) with increasing mole %, which indicates that there is specific salvation taking place with change of solvent composition. The iso kinetic temperature was found to be 253.84 K/Mole² which is less than 300, indicates weak solvent solute interaction in the reaction media.
