| titleOfInvention | Method for preparing sucrose polyether carbonate polyol |
| abstract | The invention discloses a method for preparing sucrose polyether carbonate polyol. The method comprises the following steps of: performing ester exchange reaction on sucrose and dimethyl carbonate (DMC) in the presence of a catalyst, cross-linking to obtain polyether carbonate polyol with certain molecular weight, reacting the polyether carbonate polyol with epoxy propane, and controlling the molecular weight and hydroxyl value of the polyether carbonate polyol according to the number of epoxy compounds. The invention has the characteristics that: the method is economic, safe, environment-friendly, low in cost and high in efficiency, and is suitable for the technical field of chemical industry. |
