| Supported ionic liquid phase (SILP) catalysts are new materials consisting of an ionic liquid metal catalyst solution highly dispersed on a porous support. The use of a non-volatile, ionic liquid catalyst phase in SILP catalysts results in a stable heterogeneous-type material with selectivity and efficiency like homogeneous catalysts. This makes the catalysts well suited for many industrial homogeneous catalysed processes like, e.g. C-C bond forming reactions, in continuous, gas-phase design using fixed-bed technology. In this contribution we report very promising results for continuous gas-phase alkene hydroformylation using a highly selective and durable silica-supported SILP Rh-bisphosphine catalyst. Additionally, the concept of continuous gas-phase SILP catalysis is introduced for related C-C bond forming reactions of industrial importance, which usually are performed in batch, liquid phase systems, e.g. hydroformylation of higher olefins and alcohol carbonylation for acetic acid production. |
