  • Patent number: 11655227
    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.

  • Publication number: 20230024745
    Abstract: An esterification process that uses an acetic acid composition from a wood acetylation process as a reactant. Even though the acetic acid composition contains impurities, such as ethyl acetate, methyl acetate, acetaldehyde, acetone, terpenes and/or terpenes derivatives, the impurities do not adversely affect the quality of the ether-ester products. This process can be economically advantageous by using cheaper acetic acid—one sourced directly from a wood acetylation process.

  • Patent number: 9388111
    Abstract: Disclosed is a method for purifying aromatic dicarboxylic acid such as isophthalic acid or terephthalic acid. The process treats a crude carboxylic acid (CCA) composition by feeding a CCA composition comprising a liquid and a solid to a filter cake formation zone to form a CCA wet cake composition and a first mother liquor stream; dewatering said CCA wet cake composition to form a dewatered CCA wet cake composition having a second liquid level that is lower than the first liquid level or having no liquid level and a second mother liquor stream; and washing the dewatered CCA wet cake composition with a wash stream in a wash zone to forma washed CCA wet cake composition and a wash liquor stream.
