Abstract

Procédé de préparation continue d'aldéhydes par réaction d'oléfines avec de l'oxyde de carbone et de l'hydrogène en présence de catalyseurs au rhodium à chaud et sous pression avec séparation par distillation des composés de départ non convertis et des fractions volatiles du produit de réaction. On utilise un mélange oxyde de carbone/hydrogène contenant de 2 à 20 ppm de soufre et on recycle à la synthèse, en tant que catalyseur, le résidu de distillation contenant des composés du rhodium en solution et du rhodium en suspension. Contre toute attente, la présence de soufre dans le gaz de synthèse conduit à de meilleurs taux de conversion et à de meilleurs rendements.
