1. 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 an organic carbonate compound from carbon monoxide and an alcohol-based compound (1);
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 organic carbonate compound;
a circulation line configured so as to enable the organic 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; and
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,
wherein the catalyst comprised by the cathode is a carbon compound containing nitrogen and a metal element,
wherein 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,
wherein the alcohol-based compound (1) comprises the alcohol-based compound eliminated in the first reactor, and
wherein the alcohol-based compound (1) is represented by the following general formula (1)
ROH  (1)
wherein R represents an organic group having 1 to 15 carbon atoms and R is selected from the group consisting of hydrocarbon group and hydrocarbon group having at least one of hydroxyl group and ether bond, the number of the hydroxyl groups in R being one in the case where R is the hydrocarbon group having at least the hydroxyl group.
