| titleOfInvention | Method for preparing levulinate by catalyzing cellulose with metal salt |
| abstract | The invention provides a method for directly preparing levulinate from cellulose, which mainly comprises the following steps: under the action of a metal salt catalyst, cellulose is subjected to alcoholysis reaction in a mixed solvent of alcohol and water to directly obtain levulinate. The metal cation of the metal salt used in the method is Al 3+ 、Sn 4+ Or Fe 3+ At least one of; the heating modes involved in the method include microwave heating and oil bath heating. The method provided by the invention can efficiently and selectively convert cellulose into the levulinate, has the advantages of mild reaction conditions, short reaction time, easy recovery of the catalyst, avoidance of the use of liquid acid or solid acid catalyst, less side reactions, low cost and environmental friendliness. |
