CARBOXYLATES IN CATALYTIC HYDROLYSIS OF ALKYLENE OXIDES |
摘要 |
The present invention relates to a process for the preparation of alkylene glycols by reacting an alkylene oxide with water in the presence of a catalytic composition including a polycarboxylic acid derivative, having in its chain molecule one or more carboxyl groups and one or more carboxylate groups, the individual carboxyl and/or carboxylate groups being separated fr om each other in the chain molecule by a separating group consisting of at leas t one atom. Preferably the polycarboxylic acid derivative is immobilised on a solid support. |
