| titleOfInvention | Process for the preparation of aldehydes by hydroformylation of olefins |
| abstract | The present invention includes a hydroformylation step of hydroformylating an olefin at a pressure of 50 to 1000 bar and a temperature of 50 to 180 ° C. using a rhodium catalyst dissolved in a homogeneous reaction medium, and extraction of the rhodium catalyst. A process for preparing an aldehyde or an aldehyde and an alcohol by hydroformylation of an olefin containing more than three carbon atoms, comprising recovering a catalyst, comprising: (a) a ligand, free of phosphorus and having a Group VIII metal and Hydroformylation is carried out in the presence of a polydentate, a rhodium complex representing an organic nitrogen compound, which can form complexes and further contain one or more tertiary nitrogen radicals which can be protonated by weak acids, and (b) optionally Isolating and partially separating the aldehyde and the alcohol, and then extracting the effluent of the hydroformylation step with an aqueous distilled acid solution. (C) distilling the aqueous acid in the presence of an inert organic solvent or solvent mixture under hydroformylation conditions and subjecting the aqueous acid extract to heat to thereby deprotonate the complex to transfer to the organic phase, and (d) A process is characterized by recycling the containing organic phase to a hydroformylation step. |
