The reaction parameters of oxychlorination of carbon monoxide to phosgene, reaction temperature, reaction timeand CO pressure were optimized. The online FT-IR technique is successfully employed for the first time to determine the composition of the product effluent. The formation rate of phosgene increases with the reaction temperature. Themaximumformation rate of phosgene is 1.2  103 mmol mL1 min1 at 375 oC. At the same time, the decomposition rate of phosgene increases with the reaction temperature, too.Ahigher pressure ofCOcan lead to a faster formation rate and a higher yield of phosgene. The catalyst is more stable at 300 8C than at 345 or 375 8C. At 415 8C the catalyst is nearly completely deactivated. The optimized reaction conditions are 300 oC, 6 min and 5 bar CO, where the cumulative yield of phosgene can reach up to 86.5%. The by-product HCl comes from the hydrolysis of phosgene or the surface reaction of CuCl2 and the residual water or the hydroxyl groups on the silica surface.CO2 is formedfromthe hydrolysis of phosgene.
