Claims (8)

1. Способ получения алкиленгликоля путем взаимодействия алкиленоксида с водой в присутствии твердой каталитической композиции, которая содержит сильно основную ионообменную смолу, координированную с одним или более анионами, которые выбирают из группы металатов, карбоксилатов, бикарбоната и бисульфита, и стабилизирующую добавку, которая представляет собой кислотную ионообменную смолу.1. A method of producing alkylene glycol by reacting alkylene oxide with water in the presence of a solid catalyst composition that contains a strongly basic ion exchange resin coordinated with one or more anions selected from the group of metalates, carboxylates, bicarbonate and bisulfite, and a stabilizing additive, which is an acidic ion exchange resin. 2. Способ по п.1, отличающийся тем, что кислотная ионообменная смола является слабо кислотной смолой метакрилатного типа.2. The method according to claim 1, characterized in that the acidic ion exchange resin is a weakly acidic methacrylate type resin. 3. Способ по п.1 или 2, отличающийся тем, что сильно основной ионообменной смолой является смола типа четвертичного аммония.3. The method according to claim 1 or 2, characterized in that the strongly basic ion-exchange resin is a quaternary ammonium type resin. 4. Способ по п.1 или 2, отличающийся тем, что сильно основной ионообменной смолой является смола типа четвертичного фосфония.4. The method according to claim 1 or 2, characterized in that the strongly basic ion-exchange resin is a resin of the Quaternary phosphonium type. 5. Способ по любому из пп.1-4, отличающийся тем, что исходя из обменной емкости или эквивалента активных центров, относительное количество кислотной ионообменной смолы составляет 10 - 200% относительно общей емкости сильно основной ионообменной смолы.5. The method according to any one of claims 1 to 4, characterized in that, based on the exchange capacity or the equivalent of active centers, the relative amount of acidic ion-exchange resin is 10-200% relative to the total capacity of the strongly basic ion-exchange resin. 6. Способ по любому из пп.1-5, отличающийся тем, что карбоксилат представляет собой формиат.6. The method according to any one of claims 1 to 5, characterized in that the carboxylate is a formate. 7. Способ по любому из пп.1-5, отличающийся тем, что карбоксилат представляет собой производное поликарбоновой кислоты, содержащее в своей молекулярной цепи одну или более карбоксильных групп и одну или несколько карбоксилатных групп, причем эти индивидуальные карбоксильные и/или карбоксилатные группы отделены друг от друга в молекулярной цепи разделяющей группой, состоящей из, по меньшей мере, одного атома.7. The method according to any one of claims 1 to 5, characterized in that the carboxylate is a polycarboxylic acid derivative containing in its molecular chain one or more carboxyl groups and one or more carboxylate groups, these individual carboxyl and / or carboxylate groups being separated from each other in a molecular chain by a separating group consisting of at least one atom. 8. Способ по п.7, отличающийся тем, что карбоксилат представляет собой цитрат.8. The method according to claim 7, characterized in that the carboxylate is a citrate.
