The challenging task of rhodium catalyzed hydroformylation with higher olefins is the efficient combination of the reaction and separation step for catalyst recovery and recycling. One promising concept is the use of organic solvent systems, which use a strong polar organic phase for the catalyst and allow a liquid/liquid-separation of product and catalyst after the reaction step. In this work, the hydroformylation reaction with 1-dodecene is presented in discontinuous lab-scale investigations as well as continuously driven in a miniplant. The hydroformylation reaction is carried out in a two-component solvent system containing propylene carbonate as polar catalyst solvent and decane as apolar product solvent. (C) 2015 Elsevier B.V.
