Abstract
In a process for the hydroformylation of alkanes, alkenes or trialkylboranes under supercritical or near-critical conditions, hydroformylation is effected using a heterogeneous catalyst in a continuous flow reactor containing a supercritical or near-critical reaction medium. Selectivity of product formation may be achieved by independently varying one of more of the temperature, pressure, catalyst, mole ratios of hydrogen and carbon monoxide and flow rate.
