Use | 2-chloro-trifluoromethylbenzene is an intermediate of the rodenticide bromoamine. This product is used for the synthesis of fine organic chemical products such as pharmaceuticals and pesticides. An intermediate of pentafluridine. used as an intermediate in the synthesis of fluorine-containing medicines, pesticides, dyes, etc. |
production method | O-chlorotoluene is obtained by light chlorination of O-chlorotoluene through side chain, there are two methods of fluorination. 1. Catalytic fluorination of antimony pentachloride. 2. Catalytic fluorination of phosphorus trichloride. The raw material consumption per 1t of product is: 1100kg of O-chlorotoluene, 2000kg of chlorine and 520kg of hydrogen fluoride. The preparation method is to add O-chlorotoluene in the reaction kettle, and then add a small amount of phosphorus trichloride, in the boiling and light into the chlorine gas, the temperature finally rises to 210~220 ℃, reaction 16 h, after the chlorine gas is passed through, O-chlorotrichlorotoluene is obtained by vacuum distillation, and then O-chlorotrichlorotoluene is added into a stainless steel reaction kettle to pass hydrogen fluoride, maintain the reaction pressure of 1.764 × 106Pa, remove excess hydrogen fluoride, and distilled to obtain a product. |
