Effect of high pressure on the rate constant of the Diels-Alder reaction between furan and maleic anhydride

The effect of high pressure (up to 700 MPa) on the rate of the Diels-Alder reaction between furan and maleic anhydride has been investigated in deuterated acetone at 20‡C. The volume effect of the reaction at atmospheric pressure is found to be δV0=−28.0 cm3/mole. The rate constants for the formation, decomposition and isomerization of the products have been found by numerical integration. The volume of activation δV≠ in the pressure range studied has been determined from the observed dependence of log k upon P by spline approximation and was found to be −30.5 cm3/mole at atmospheric pressure, close to the volume change in the reaction, which is consistent with the assumption of a conjugated cyclic transition state.
