Title:
HYDROFORMYLATION PROCESS
Document Type and Number:
Japanese Patent JP2021008477
Kind Code:
A
Abstract:
To provide a means of separating high-boiling aldehydes from a rhodium-organophosphite hydroformylation catalyst while reducing the loss of rhodium.SOLUTION: A continuous hydroformylation process includes: (a) removing a reaction fluid from a reactor 100; (b) sending the reaction fluid to a vaporizer 200; (c) separating the reaction fluid in the vaporizer to produce a catalyst-containing liquid stream and a gas phase stream; and (d) maintaining an average CO partial pressure in the vaporizer of greater than 16 psia (110 kPa).SELECTED DRAWING: Figure 1
