Catalytic hydropolymerization of olefins and their hydrocondensation with carbon monoxide

Abstract

1. Catalytic hydrocondensation reactions of CO with olefins and the hydropolymerization of the latter in the presence of H2 under the influence of small quantities of CO lead to the synthesis of mixtures of aliphatic hydrocarbons, predominantly of straight-chain structure, with a considerable proportion of higher olefins. 2. These reactions take place with the formation of active surface intermediates products of incomplete reduction of CO and semihydrogenated olefin species – which influence their rates and nature. 3. Carbon monoxide in a mixture with hydrogen behaves, on the one hand, as a methylating agent or an agent responsible for the formation of higher homologs, and on the other, as an initiator of the olefin hydropolymerization. 4. The major role of hydrogenolysis in the formation of active species on the catalyst surface has been demonstrated on the example of a new reaction — destructive hydropolymerization of isobutene.
