On the catalytic activity of certain synthetic organic polymers

Abstract

1. Data were obtained on the catalytic activity of synthetic polymers with conjugated bondspolymethyl vinyl ketone and polyparadiethynylbenzene in reactions of ortho-para and para-ortho conversion of hydrogen and isotopic exchange of hydrogen with deuterium. 2. The indicated polymers manifest catalytic activity in the reaction of para-ortho conversion of hydrogen at high temperatures and in the reaction of ortho-para conversion of hydrogen at the temperature of liquid nitrogen. The kinetic principles correspond to a first-order reaction rate equation (according to the change in pressure). The reaction of isotopic exchange of hydrogen with deuterium practically does not occur in the presence of these polymers. 3. A comparison of the results obtained with the physical properties of the polymers shows that the reaction of para-ortho conversion evidently proceeds according to a unique physical mechanism, on account of the influence of the surface paramagnetic centers, the appearance of which is related to the presence of complexes with charge transfer.
