  • Patent number: 10633750
    Abstract: Various embodiments disclosed relate to electrocatalytic hydrogenation of muconic acid and polymers formed from the reaction products thereof. In various embodiments, the present invention provides an electrocatalytic method to prepare 3-hexene-1,6-dioic acid, 2-hexene-1,6-dioic acid, adipic acid, or a combination thereof, from muconic acid. The method includes passing current through a catalytic cathode in a reactor including an aqueous acidic solution including muconic acid, a supporting electrolyte, and an anode, so as to generate atomic hydrogen on the cathode surface in an amount effective to hydrogenate the muconic acid to yield a product including 3-hexene-1,6-dioic acid, 2-hexene-1,6-dioic acid, adipic acid, or a mixture thereof. Also disclosed is the polymerization of 3-hexene-1,6-dioic acid, 2-hexene-1,6-dioic acid, or a combination thereof with another compound, such as a diamine or a dialcohol, to form a polymer, such as a polyamide or a polyester.

  • Patent number: 10465043
    Abstract: Various embodiments disclosed relate to electrochemical isomerization of muconic acid. In various embodiments, the present invention provides a method to prepare trans,trans-muconic acid. The method can include passing current through a catalytic cathode in a reactor including an aqueous acidic solution including cis,trans-muconic acid, a supporting electrolyte, and an anode, so as to isomerize the cis,trans-muconic acid to yield a product including trans trans-muconic acid.
