Abstract
Official abstract text for this publication.
Provided is a synthesis method comprising a first step of producing a carbonate compound from carbon monoxide and an alcohol-based compound at an anode of a first electrochemical cell comprising a cathode and the anode, and a second step of synthesizing a first product by a dealcoholization reaction of the carbonate compound, wherein an alcohol-based compound eliminated in the second step is recycled in the first step.
First claim
Opening claim text (preview).
1 - 9 . (canceled) 10 . A synthesis system comprising: a first electrochemical cell comprising a cathode and an anode, wherein the anode comprises a catalyst that catalyzes a reaction for production of a carbonate compound from carbon monoxide and an alcohol-based compound; a first gas feed line that feeds carbon monoxide to the side of the anode of the first electrochemical cell; a first reactor that produces a first product by a dealcoholization reaction of the carbonate compound; and a circulation line configured so as to enable the carbonate compound produced at the side of the anode of the first electrochemical compartment to be fed to the first reactor and enable an alcohol-based compound eliminated in the first reactor to be fed to the side of the anode of the first electrochemical cell. 11 . The synthesis system according to claim 10 , comprising: a second reactor that produces a second product by a dealcoholization reaction of the first product produced in the first reactor; and a feed pathway that feeds an alcohol-based compound eliminated in the second reactor, to the side of the anode of the first electrochemical cell. 12 . The synthesis system according to claim 10 , comprising a second gas feed line that feeds carbon dioxide to the side of the cathode of the first electrochemical cell, wherein the cathode of the first electrochemical cell comprises a catalyst that reduces carbon dioxide to carbon monoxide; and the first gas feed line is a connecting path that connects the side of the cathode of the first electrochemical cell to the side of the anode thereof. 13 . The synthesis system according to claim 10 , comprising: a second electrochemical cell comprising a cathode and an anode, wherein the cathode comprises a catalyst that reduces carbon dioxide to carbon monoxide; and a third gas feed line that feeds carbon dioxide to the side of the cathode of the second electrochemical cell, wherein the first gas feed line is a connecting path that connects the side of the cathode of the second electrochemical cell and the side of the anode of the first electrochemical cell.
