Abstract

La préparation de propanediol-1,3 s'effectue dans le cadre d'un procédé faisant réagir de l'oxyde d'éthylène avec du monoxyde de carbone et de l'hydrogène dans un solvant quasiment non miscible à l'eau en présence d'une quantité efficace d'un catalyseur au cobalt dépourvu de ligand du type phosphine et d'une quantité efficace d'un promoteur catalytique et ce, dans des conditions de réaction à même de produire un mélange intermédiaire comportant moins de 15 % en poids d'hydroxypropanal-3. A partir de ce mélange, on extrait l'hydroxypropanal-3 dans l'eau sous une forme davantage concentrée, la majeure partie du catalyseur au cobalt demeurant dans la phase solvant pour recyclage aux fins de la réaction d'hydroformylation. On débarrasse, partiellement du moins, la phase aqueuse suivant l'extraction de tout catalyseur résiduel par le biais d'une nouvelle extraction faisant intervenir un solvant non miscible à l'eau, puis on recycle cette phase aux fins de la réaction d'hydroformylation. L'hydroxypropanal-3 est alors hydrogéné dans une solution aqueuse jusqu'à obtenir le propanediol-1,3 désiré.
