Abstract:
Disclosed is a purified dialkyl furan dicarboxylate (DAFD) vapor composition containing at least 99.5 wt. % DAFD; 5-(alkoxycarbonyl) furan-2-carboxylic acid (ACFC) that, if present, is present in an amount of not more than 1000 ppm, alkyl-5-formylfuran-2-carboxylate (AFFC) that, if present, is present in an amount of not more than 1000 ppm, 5-(dialkoxymethyl)furan-2-carboxylic acid (DAFCA) that if present, is present in an amount of not more than 1000 ppm, and alkyl 5-(dialkoxymethyl)furan-2-carboxylate (ADAFC) that if present, is present in an amount of not more than 1000 ppm, in each case based on the weight of the DAFD vapor composition.

Claim (Index 1):
A process for the manufacture of a DAFD vapor comprising:\n a. feeding a furan-2,5-dicarboxylic acid (\u201cFDCA\u201d) composition to an esterification reaction zone; and b. in the presence of an alcohol compound, conducting an esterification reaction in the esterification reaction zone to react FDCA with said alcohol compound to form a crude diester composition comprising dialkyl furan-2,5-dicarboxylate (\u201cDAFD\u201d), the alcohol compound, 5-(alkoxycarbonyl)furan-2-carboxylic acid (ACFC), alkyl furan-2-carboxylate (AFC), alkyl-5-formylfuran-2-carboxylate (AFFC), 5-(dialkoxymethyl)furan-2-carboxylic acid (DAFCA) and alkyl 5-(dialkoxymethyl)furan-2-carboxylate (ADAFC), and 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, AFFC, DAFCA, and ADAFC 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 d. separating at least a portion of DAFD from the first liquid DAFD rich composition in a product recovery zone; wherein the process produces a composition comprising:\n (i) at least 99.5 wt. % DAFD; \n (ii) 5-(alkoxycarbonyl)furan-2-carboxylic acid (ACFC) that if present, is present in an amount of not more than 1000 ppm, \n (iii) alkyl-5-formylfuran-2-carboxylate (AFFC) that if present, is present in an amount of not more than 1000 ppm \n (iv) 5-(dialkoxymethyl)furan-2-carboxylic acid (DAFCA) that if present, is present in an amount of not more than 1000 ppm, and \n (v) alkyl 5-(dialkoxymethyl)furan-2-carboxylate (ADAFC) that if present, is present in an amount of not more than 1000 ppm, \n in each case based on the weight of the DAFD vapor composition.
