Abstract:
Disclosed are processes for producing the dialkyl ester of 2,5-furan dicarboxylic acid by contacting a feed containing 2,5-furan dicarboxylic acid and a high boiling solvent with an alcohol in the presence of a solid acid catalyst using reactive distillation.

Claim (Index 10):
A process comprising:\n a) providing a reactive distillation column comprising a top, a bottom, and a reaction zone in between the top and the bottom, and a solid acid catalyst situated in the reaction zone; b) contacting a feed comprising 2,5-furan dicarboxylic acid and a high boiling solvent with an alcohol in the reaction zone at a temperature in the range of 40\u00b0 C. to 300\u00b0 C. and a pressure in the range of 0.0007 MPa to 3.4 MPa for a residence time sufficient to produce a vapor mixture of a dialkyl ester of 2,5-furan dicarboxylic acid, water and optionally, a monoalkyl ester of 2,5-furan dicarboxylic acid; c) removing a vapor mixture comprising the dialkyl ester of 2,5-furan dicarboxylic acid, the alcohol, water, and optionally the monoalkyl ester of 2,5-furan dicarboxylic acid from the top of the reactive distillation column; d) collecting the high boiling solvent, optionally one or more of a monoalkyl ester of 2,5-furan dicarboxylic acid, any unreacted 2,5-furan dicarboxylic acid, and any other high boilers from the bottom of the reactive distillation column; and e) separating the dialkyl ester of 2,5-furan dicarboxylic acid from the vapor mixture using distillation.
