| titleOfInvention | Method for producing high-purity carbon tetrachloride |
| abstract | PROBLEM TO BE SOLVED: To convert bromochloromethanes, particularly bromochloromethanes in crude carbon tetrachloride containing bromodichloromethane, into carbon tetrachloride extremely easily, and it is practical only by distillation alone Provided is a method for producing carbon tetrachloride that can obtain high-purity carbon tetrachloride that cannot be achieved at a high purity. SOLUTION: In a method for producing high-purity carbon tetrachloride from crude carbon tetrachloride containing bromochloromethanes, In the presence of chlorine, 200 nm to 500 n Irradiation with ultraviolet light or visible light having a wavelength of m is performed, and if necessary, high-boiling substances are removed by distillation to obtain high-purity carbon tetrachloride. |
