<p>A CONTINUOUS HYDROFORMYLATION PROCESS FOR FORMING AN ALDEHYDE COMPRISING: A) REACTING AN OLEFINICALLY UNSATURATED COMPOUND CONTAINING FROM 6 TO 30 CARBON ATOMS, CARBON MONOXIDE, HYDROGEN, AND A RHODIUM-BISPHOSPHITE LIGAND COMPLEX CATALYST TO FORM A REACTION MIXTURE, B) SEPARATING ALDEHYDE PRODUCT FROM AT LEAST A PORTION OF SAID REACTION MIXTURE, RESULTING IN AN ALDEHYDE CONTAINING PRODUCT STREAM AND A CATALYST CONTAINING PRODUCT STREAM, AND C) RECYCLING THE CATALYST CONTAINING STREAM TO A),WHEREIN SAID SEPARATION IS ACCOMPLISHED IN A VACUUM EVAPORATOR AND A VAPOUR/LIQUID SEPARATOR AND WHEREIN THE TEMPERATURE OF THE HEATING SURFACE OF THE EVAPORATOR IS LESS THAN 125°C AND THE RESIDENCE TIME OF THE CATALYST IN THE EVAPORATOR IS LESS THAN 15 MINUTES.</p> |
