| titleOfInvention | Purification method and production method of carbonyl fluoride |
| abstract | According to the present invention, the purified gas is reacted with the impurities in the carbonyl fluoride crude product gas to remove the impurities in the carbonyl fluoride crude product gas, and the purified gases are ClF, ClF 3 , ClF 5 , and F. The present invention provides a method for purifying carbonyl fluoride, which comprises any one or more of 2 . The purification method, the crude reaction product of carbonyl fluoride is purified, and any one or more of ClF, ClF 3 , ClF 5 , and F 2 is used as a purified gas, and the reaction of carbonyl fluoride is performed in the purification apparatus. React with the crude product to remove various impurities other than carbonyl fluoride, especially impurities such as CO 2 , CO, H 2 O, phosgene (COCl 2 ), N 2 O, and reduce the content of impurities . The purified carbonyl fluoride purified gas has COF 2 purity 99.9 99.95%, CO 2 content ≦ 150 × 10 −6 (volume ratio), COCl 2 content ≦ 150 × 10 −6 (volume ratio) is there. |
