1. A method of producing phosgene, comprising:
reacting carbon monoxide and chlorine in a phosgene reactor in the presence of a catalyst to produce a final product composition comprising phosgene; wherein carbon tetrachloride is present in the final product composition in an amount of 0 to 10 ppm by volume, based on the total volume of phosgene; wherein the phosgene reactor comprises a tube, a shell, and a space located between the tube and the shell; and wherein the catalyst is disposed in the tube and a cooling medium is located in the space, or the catalyst is disposed in the space and a cooling medium is located in the tube.
