PROCEDE D'HYDROFORMYLATION D'UNE OLEFINE, AMELIORE PAR LE CHOIX DU SOLVANT DE REACTION ET LE CONTROLE DES PARAMETRES D'EXTRACTION DU PRODUIT

摘要

In hydroformylating an olefinic compound to produce an aldehyde derivative thereof employing as catalyst a complex of a Group VIII metal and an organic ligand dissolved in an inert liquid reaction solvent with the aldehyde product being continuously stripped out of the solvent, stripping is facilitated while by-product formation is kept at a minimum by using a solvent of specially-chosen high molecular weight (of at least 700) while also controlling the degree of stripping as desired to maintain in the reaction medium a controlled molar concentration of the aldehyde hydroformylation product.
