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.

Claim (Index 3):
The process of  claim 1 , wherein the catalyst, if present, is cobalt (II) acetate, iron (II) chloride, iron (III) chloride, iron (II) sulfate, iron (III) sulfate, iron (II) nitrate, iron (III) nitrate, iron (II) oxide, iron (III) oxide, iron (II) sulfide, iron (III) sulfide, iron (II) acetate, iron (III) acetate, magnesium (II) acetate, magnesium (II) hydroxide, manganese (II) acetate, phosphoric acid, sulfuric acid, zinc (II) acetate, zinc stearate, a solid acid catalyst, a zeolite solid catalyst, or a combination thereof.
