Abstract

Cette invention se rapporte au domaine des procédés catalytiques permettant de produire des alkylèneglycols. Cette invention concerne plus particulièrement un procédé de préparation d'alkylèneglycols consistant à hydrater des oxydes d'alkylène. Cette hydratation se déroule en présence d'un système catalytique à base de matériaux polymères à échange ionique et contenant de l'azote, lesquels matériaux contiennent en qualité de centres électriques positifs des atomes d'azote qui sont coordonnés à des anions. Au moins un des centres électriques positifs est coordonné à un anion d'acides di- et/ou tri- et/ou polybasiques dont au moins un atome d'hydrogène est substitué par un ion d'un atome de métal du groupe I de la classification périodique et/ou par un ion d'ammonium. L'hydratation des oxydes d'alkylène peut se faire à une température de 20 à 200° C et à une pression de 0,6 à 5,0 MPa. La température et la pression varient de préférence dans des plages allant de 80 à 130° C et de 1,0 à 2,0 MPa, respectivement.
