EFFECT OF PRESSURE ON THE DIELS-ALDER REACTION BETWEEN FURAN AND METHYL ACRYLATE

Article abstract of DOI:10.1007/BF00958867

A study was carried out on the effect of pressure up to 1400 MPa on the Diels-Alder reaction between furan and methyl acrylate at 20 deg C.At atmospheric pressure, the reaction proceeds with 20percent yield after two months, while it proceeds at 1400 MPa with 70percent yield after 2.5 h.The observed volumetric activation effect (-ΔV_p(excit.)) of this reaction decreases relatively slightly with increasing pressure and its value at 0.1 MPa (20 cm³/mole) is markedly less than the change in volume upon reaction (-ΔV₀ = 29 cm³/mole).The ratio of the endo and exo isomers formed is 2.6 and is independent of the pressure.
