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.

Disclosed herein is a method for making oleofuran compounds according to formula 3

##STR00001##

from a furan aldehyde or ketone and a fatty alcohol. The method comprises combining the furan compound and the fatty acid in the presence of a first catalyst to form an intermediate compound, and exposing the intermediate compound to hydrogen in the presence of a second catalyst to form the oleofuran compound. The hydrogen may be either hydrogen gas or hydrogen provided by a hydrogen donor.
