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 13):
The process of  claim 2  wherein step d comprises separating at least a portion of alcohol from the first liquid DAFD rich composition using a physical separation process to produce:\n d (i) a second alcohol composition that is rich in the concentration of alcohol relative to the concentration of alcohol in the first liquid DAFD rich composition; and \n d(ii) a second liquid DAFD rich composition comprising DAFD that is rich in the concentration of DAFD relative to the concentration of DAFD in the first liquid DAFD rich composition; and \n wherein said process further comprises:\n separating at least a portion of AFC from the second liquid DAFD rich composition using a physical separation process to produce: \n e(i) a vapor AFC composition that is rich in the concentration of AFC relative to the concentration of AFC in the second liquid DAFD rich composition; and \n e(ii) a partially purified liquid DAFD rich composition comprising DAFD and ACFC that is rich in the concentration of DAFD relative to the concentration of DAFD in the second liquid DAFD rich composition; and \n separating at least a portion of the DAFD from the partially purified DAFD rich composition using a physical separation process to produce: \n f(i) a purified DAFD vapor composition rich in the concentration of DAFD relative to the concentration of DAFD in the partially purified liquid DAFD rich composition; and \n f(ii) a liquid ACFC composition that is rich in the concentration of ACFC relative to the concentration of ACFC in the partially purified liquid DAFD rich composition.
