Summary

A kinetic study of the hydroformylation of 1-heptene by a [Rh(NBD)Cl]2/PPh3 system, taking into account possible gas-liquid mass-transfer restrictions, is presented. The catalytic activity in different solvents is evaluated. With Me2CO as solvent, the kinetic Equation (1) is obtained.

$$Rate = - dC/dt = k' C^{{1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} {\text{C}}_{{\text{Rh}}} ^{{1 \mathord{\left/ {\vphantom {1 4}} \right. \kern-\nulldelimiterspace} 4}} ({\text{P}}_{{\text{H}}_2 } /{\text{P}}_{{\text{CO}}} )^{{1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} $$

The apparent rate constants for the formation of n-and isoaldehydes, and their temperature variation, account for the selectivity change with temperature. The overall mass-transfer coefficient (kLa) has been evaluated from mass-transfer considerations and rate data.
