METHOD FOR PREPARING LEVULINIC ACID USING SOLID ACID CATALYST IN PRESENCE OF ETHYLENE GLYCOL-BASED COMPOUND SOLVENT DERIVED FROM BIOMASS 바이오매스 유래 에틸렌 글리콜계 화합물 용매 하의 고체 산 촉매를 이용한 레블리닉산의 제조방법

摘要

Provided is a method for preparing levulinic acid using a solid acid catalyst in a condition with the presence of an ethylene glycol-based compound. The levulinic acid according to the present invention can be prepared by using a linear or cyclic ethylene glycol-based compound as a solvent, and preparing the levulinic acid from fructose in the presence of the solid acid catalyst, at a reaction temperature of 100 to 200℃, thereby reducing dependency on petroleum responding to greenhouse gas regulations. Also, a high yield of levulinic acid can be obtained from fructose, and the solvent and the catalyst can be efficiently separated, collected, and reused after the a reaction has been concluded.
