Kinetics of thermal dimerizations of cyclopentadiene and methylcyclopentadienes and their codimerization

Popis výsledku v původním jazyce

The kinetics of the formation of isomeric dimers and codimers via thermal dimerization and codimerization between cyclopentadiene, 1-methyl-1,3-cyclopentadiene and 2-methyl-1,3-cyclopentadiene were studied. The laboratory experiments were carried out ina 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. The overall rates of cyclopentadiene and methylcyclopentadiene dimerizations and their mutual codimerization were found to be identical throughout the temperature range in which the reactions are kinetically controlled. Thepresence of a methyl group on the cyclopentadiene ring does not decrease the reactivity of the monomer in the Diels-Alder reaction. The reactivities of both methylcyclopentadiene isomers are the same.
