| titleOfInvention | Method of processing liquid stream after hydroformylation |
| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to a method of processing a hydroformylation reaction liquid product which contains an aldehyde, high-boiling hydroformylation reaction by-products, a homogeneously dissolved rhodium complex catalyst, an unreacted olefinically unsaturated compound, synthesis gas and volatile by-products, in which a) the liquid stream after hydroformylation is throttled in an expansion tank, wherein there is separation into a liquid phase and a gas phase, b) the liquid phase obtained in the expansion tank is fed into a separation device in which there is separation into a liquid phase, which mainly contains high-boiling hydroformylation reaction by-products, a homogeneously dissolved rhodium complex catalyst and a small amount of aldehyde, and a gas phase which contains the bulk of the aldehyde, and c) a liquid rhodium-containing stream is collected from the separation device. A portion of the liquid rhodium-containing output stream collected from the separation device is removed from the process and the other portion is passed through a filter, and the separated solid substances are removed from the process while the obtained filtrate is returned to the hydroformylation reaction. n EFFECT: method enables to prevent breakdown and/or deactivation of the hydroformylation catalyst. n 13 cl, 1 ex, 1 dwg |
