Title (EN) COPOLYETHER GLYCOL MANUFACTURING PROCESS
(FR) PROCÉDÉ DE FABRICATION DE COPOLYÉTHER GLYCOL
Abstract: front page image
(EN)The present invention relates to a continuous process for manufacturing copolyether glycols with high incorporation of alkylene oxide by polymerization of tetrahydrofuran and at least one alkylene oxide in the presence of an acid catalyst, at least one compound containing reactive hydrogen atoms, and a specific diluent or solvent. More particularly, the invention relates to a diluent or solvent-assisted continuous process for manufacturing copolyether glycols with high incorporation of alkylene oxide.
(FR)La présente invention porte sur un procédé continu pour fabriquer des copolyéther glycols avec incorporation élevée d'oxyde d'alkylène par polymérisation de tétrahydrofurane et d'au moins un oxyde d'alkylène en présence d'un catalyseur acide, au moins un composé contenant des atomes d'hydrogène réactifs et un diluent ou solvant spécifique. Plus particulièrement, l'invention porte sur un procédé continu assisté par diluant ou solvant pour fabriquer des copolyéther glycols avec une incorporation élevée d'oxyde d'alkylène.
