Abstract

The reaction of cyclopropane with hydrogen has been studied over evaporated and pumice-supported nickel catalysts. It has been found that reproducibility of reaction behaviour on a particular catalyst is controlled by a number of factors. In cases where reproducibility has been obtained poisoning of the hydrogenation reaction by mercury has been studied using a radiotracer technique. The results of this study indicate that, when allowance has been made for differences in film weight, a particular amount of mercury does not produce a comparable effect on different films, although, when only relative effects are considered, reproducibility between films is obtained. A comparison of the poisoning curve so derived with those in the literature confirms that on evaporated nickel films the mechanism of the poisoning process is the prevention by mercury of hydrogen adsorption; a process necessary for hydrogenation of cyclopropane.
