Abstract
The rates of ethanolysis of p-nitrophenyl chloroformate in acetone were measured using the titration method at 25oC. From these rate constants, plots of the experimental second-order rate constant against the initial ethanol concentration were linear. From the kinetics data obtained, p-nitrophenyl chloroformate was found to be represented by d[HCl]/[dt = k2[p-NPC][EtOH] + k3[p-NPC][EtOH]2. The values of activation enthalpy and entropy for the ethanolyses of p-nitrophenyl chloroformate was determined from the rate constants measured at various temperatures. From these results, the reaction of these substrates with ethanol in acetone was mixed second- and third-order reaction for over-all reaction, and it could be estimated that this reaction has bimolecular addition-elimination mechanism.
