Abstract
AbstractThe procedural rate enhancement of a liquid‐liquid gas reaction system by example of the biphasic hydroformylation of 1‐octene in miniplant scale is presented. Different stirring techniques were applied on a lean reaction system without the use of chemical additives to increase the internal surface area. Reaction rates were doubled compared to standard laboratory stirring methods. While the reaction rate showed a logarithmic relation towards the rate of energy dissipation, it was nearly linearly related to the created interfacial area between organic and aqueous phase. Obtained results support the intensively discussed theory that the reaction takes place at the surface. This study also underlines the importance of procedural optimization in multiphase reactions.
