  • Patent number: 11104656
    Abstract: The invention is based on the finding that when conducting crystallization of FDCA at high temperatures, the formation of significant amounts of colored byproduct can be reduced or even avoided when the FDCA mixture is kept at temperatures above 100° C. for less than 15 minutes. This is achieved by conducting the crystallization process in a continuous reactor. Accordingly, the method comprises the steps of feeding a mixture comprising undissolved FDCA and a solvent to a reactor; and dissolving FDCA by superheating the mixture in the reactor to a temperature of at least 130° C.; and crystallizing FDCA by cooling the mixture in the reactor, wherein the reactor is a continuous reactor and the residence time in the reactor zone wherein the FDCA mixture has a temperature above 100° C. is less than 15 minutes.

  • Patent number: 9327241
    Abstract: A method for treating a contaminated alkaline amino acid salt solution is provided. First, carbon dioxide is introduced into the amino acid salt solution, with the result that carbonate or carbonate salts is or are precipitated, these being filtered off. The remaining filtrate is then cooled, amino acid or amino acid salts being crystallized out and likewise being filtered off. The amino acid or amino acid salt is then dissolved again, with the result that a treated amino acid salt solution is recovered.
