Abstract
A method for controlling a hydroformylation reaction for producing an aldehyde by subjecting an olefin, a feed oxo gas containing hydrogen and carbon monoxide, and a recycled gas withdrawn from a reactor and returned to the reactor, to a hydroformylation reaction in the reactor in the presence of a catalyst, which comprises: PA1 setting out a target value for the partial pressure of carbon monoxide in the reaction system to control the hydroformylation reaction; PA1 detecting the partial pressure of carbon monoxide corresponding to the target value; and PA1 comparing the detected partial pressure of carbon monoxide with the target value to adjust a flow rate of a discharged gas from the reactor; or PA1 comparing the detected partial pressure of carbon monoxide with the target value to adjust a flow rate of the feed oxo gas.
