  • Esterification of 2,5-Furan-Dicarboxylic Acid
    Publication number: 20150315166
    Abstract: A method of making a furan dicarboxylate by means of reacting 2,5-furan dicarboxylic acid (FDCA) with an alcohol or mixture of alcohols in a CO2-predominant atmosphere without the presence of any other acid catalyst is described. The reaction is conducted under conditions that correspond to either supercritical, critical or near-critical temperatures and pressures for the alcohol species and/or CO2 gas.

  • Diallyl ethers of 2,5bis(hydroxymethyl)tetrahydrofuran and processes for making the same
    Patent number: 9139545
    Abstract: The diallyl ether derivatives of the cis and trans stereoisomers of 2,5-bis(hydroxymethyl)tetrahydrofuran are produced. These materials are expected to be useful for making a variety of biobased polymers. Processes are further described for producing these diallyl ether derivatives in substantially quantitative yields.
