Abstract
The complicated and partially controversial formulations of the various steps and branchings in the hydroformylation process are comprised in a reaction scheme that neglects the production of different isomers and isomerisations of olefins and is a compromise between the given complexity and a theoretical tractability. Special consideration is devoted to the inhibition of the process by one of its substrates, CO. In a first approximation complete inertness of the Co-tetracarbonyls is assumed and the existence of bistability and hysteresis for particular parameter combinations is proved. In the further treatment this approximation is again relaxed. Technological consequences of the analysis are discussed.
