  • Electrochemical isomerization of muconic acid
    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.
    Type: Grant
