The hydrolysis of propyl formate in binary water+propanol-2 mixture was investigated volumetrically for kinetic studies. The rate of reaction decreases continuously with decreasing concentration of water at all varying temperatures ranging from 20 to 40⁰C.The iso-composition activation energy (E_C) rises with increasing proportion of solvent. The kinetics of the reaction was also investigated in term of solvent composition, water concentration and dielectric constant. The thermodynamic activation parameters were also calculated.
