| titleOfInvention | Production of carbonyl halide |
| abstract | Carbonyl halide is produced from carbon monoxide and halide anions produced from the electrochemical conversion of essentially anhydrous hydrogen halide. Both the oxidation of anhydrous hydrogen halide and the formation of carbonyl halide are carried out in the anode-compartment of an electrochemical cell. This eliminates the need for multiple pieces of equipment for carrying out these reactions. Moreover, no catalyst is needed to form halide anions and subsequently make carbonyl halide, as in the prior art. In addition, the health hazards associated with making a carbonyl halide, such as phosgene, at high temperatures from chlorinated hydrocarbons with atmospheric oxygen are virtually eliminated. Furthermore, the halide anions produced as a result of the oxidation of anhydrous hydrogen halide are dry, thereby eliminating the need for a preheater before the halide anions are reacted with carbon monoxide. Thus, with the present invention, carbonyl halide may be produced more easily, more safely and more inexpensively as compared to prior art processes. |
