要旨

The reaction engineering kinetics for the hydroformylation of the post-metathesis product 7-tetradecene using the bulky phosphite-modified rhodium catalyst Rh-tris(2,4-di-tertbutylphenyl)phosphite were evaluated. The reaction was performed at different temperatures (60 to 90 °C), catalyst concentrations (0.5 to 1 mM), hydrogen partial pressures (15 to 25 bar) and carbon monoxide partial pressures (15 to 25 bar). The reaction system is well described by three interdependent mole balance equations in combination with a phenomenological mechanism-based rate law equation derived for the bulky phosphite ligand coordinated to rhodium. The kinetics were thus found to be first-order in alkene and catalyst concentrations (above a critical concentration), negative-order in carbon monoxide and zero-order in hydrogen. The activation energy for the hydroformylation reaction was calculated to be 68 kJ mol−1.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
