Kinetics of cycloaddition reactions of conjugated C5 dienes

Popis výsledku v původním jazyce

The kinetics of the formation of isomeric dimers and codimers via thermal dimerization and codimerization between 1,3-cyclopentadiene, isoprene, cis-1,3-pentadiene and trans-1,3-pentadiene were studied. The laboratory experiments were carried out in a batch reactor in a cyclohexane solution at different temperatures. Measured concentrations of the reactants and 1:1 Diels-Alder adducts were fitted to the kinetic model. Kinetic parameters for formation of the individual isomeric products and the summary reactions were determined. It was found that the activation energies of dimerizations of acyclic C5 dienes are by 20-40 kJ/mol higher than that of the dimerization of cyclopentadiene, and the activation energies of the formation of codimers of cyclopentadiene with 1,3-pentadienes are higher by 10-20 kJ/mol.
