  • MULTI-STAGE ESTERIFICATION PROCESS
    Publication number: 20220259169
    Abstract: A process for efficiently esterifying furan dicarboxylic acid, especially 2,5-furan dicarboxylic acid in the presence of an alcohol and, optionally, a catalyst is disclosed. The process provides high yields of the diesters of furan dicarboxylic acid and comprises a multi-stage esterification process wherein a portion of a gas phase is removed at each stage of the multi-stage process.
    Type: Application

  • LOW PRESSURE, HIGH TEMPERATURE PROCESS FOR FORMING 2,5-FURANDICARBOXYLIC ACID DIALKYL ESTER
    Publication number: 20190031633
    Abstract: Processes for preparing a dialkyl ester of 2,5-furan dicarboxylic acid are disclosed. The processes comprise contacting 2,5-furan dicarboxylic acid with excess alcohol and, optionally, a catalyst at a pressure in the range of between 1 bar and 21 bar and a temperature in the range of from 65° C. to 325° C. to form a vapor reaction product comprising an ester of 2,5-furan dicarboxylic acid, the alcohol and water; and distilling the vapor reaction product at a pressure in the range of from 0 bar to 3.5 bar at a temperature in the range of from 38° C. to 204° C. to separate the water and alcohol from the ester of 2,5-furan dicarboxylic acid.
