  • 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: 11053209
    Abstract: A highly efficient, Z-selective ring-closing metathesis system for the formation of macrocycles using a stereoretentive, ruthenium-based catalyst supported by a dithiolate ligand is reported. This catalyst is demonstrated to be remarkably active as observed in initiation experiments showing complete catalyst initiation at ?20° C. within 10 min. Using easily accessible diene starting materials bearing a Z-olefin moiety, macrocyclization reactions generated products with significantly higher Z-selectivity in appreciably shorter reaction times, in higher yield, and with much lower catalyst loadings than in previously reported systems. Macrocyclic lactones ranging in size from twelve-membered to seventeen-membered rings are synthesized in moderate to high yields (68-79% yield) with excellent Z-selectivity (95%-99% Z).
