THE REACTION BETWEEN 2-METHOXYFURAN AND DIMETHYLACETYLENEDICARBOXYLATE - THERMOCHEMICAL AND KINETIC DATA

The Diels-Alder reaction between methoxyfuran and dimethylacetylenedic arboxylate, leading to a substituted oxanorbornadiene, has not yet bee n studied in terms of its thermodynamic and kinetic properties, in ord er to use this liquid phase reaction for storage and release of therma l energy. Here, the reaction enthalpy and kinetic parameters are deter mined by dynamic modelling which uses only the experimental temperatur e of the reaction mixture versus time and the known kinetic law (secon d order). NMR spectroscopy is used for structural identification of th e adduct and for determining the relative ratio of reactants and produ ct, allowing the kinetic constant to be obtained. Results obtained by modelling are compared with those of other Diels-Alder reactions curre ntly studied, This reaction has suitable thermodynamic and kinetic pro perties for thermal energy storage and release. We discuss the conditi ons of such an application.
