Abstract:
Disclosed is a process to produce a purified vapor comprising dialkyl-furan-2,5-dicarboxylate (DAFD). Furan-2,5-dicarboxylic acid (FDCA) and an alcohol in an esterification zone to generate a crude diester stream containing dialkyl furan dicarboxylate (DAFD), unreacted alcohol, 5-(alkoxycarbonyl)furan-2-carboxylic acid (ACFC), and alkyl furan-2-carboxylate (AFC). The esterification zone comprises at least one reactor that has been previously used in an DMT process.

Claim (Index 2):
The process according to  claim 1  further comprising\n c) separating at least a portion of the alcohol compound from the crude diester composition in a flash zone using a physical separation process to produce: \n (i) a vapor alcohol composition, comprising said alcohol compound, taken as an overhead stream that is rich in the concentration of alcohol, relative to the alcohol concentration in the crude diester composition feeding the flash zone, and \n (ii) a first liquid DAFD rich composition, comprising DAFD, ACFC, AFC, and AFFC, that is rich in the total concentration of DAFD relative to the total concentration of DAFD in the crude diester composition feeding the flash zone; and\n separating at least a portion of DAFD from the first liquid DAFD rich composition in a product recovery zone; \n \n wherein the process produces:\n (i) a purified DAFD vapor composition rich in the concentration of DAFD relative to the concentration of DAFD in the first liquid DAFD rich composition; and \n (ii) a liquid ACFC composition that is rich in the concentration of ACFC relative to the concentration of ACFC in the first liquid DAFD rich composition; \n (iii) a vapor AFC composition comprising AFC that is rich in the concentration of AFC relative to the concentration of AFC in the first liquid DAFD rich composition; and \n (iv) a second alcohol composition comprising alcohol that is rich in the concentration of alcohol, relative to the first liquid DAFD rich composition.
