Abstract
The invention discloses a technology for producing ester of carboxylic acid using cellulosic biomass as starting material. This technology comprises the following key steps: converting all of the organic polymers, including such high molecular-weight polymers as carbohydrate components and lignin, in cellulosic biomass into water soluble, small molecular organics completely in relatively short time under relatively mild conditions; separating the resultant water soluble compounds containing aromatic rings by adjusting the acidity/basicity of the reaction solution or by using adsorption resin; and converting the water soluble compounds containing aromatic rings into ester of carboxylic acid by hydrogenation and esterification in a corresponding alcohol solution.
