| use | chloropicrin is a kind of warning fumigation agent, which can kill insects, sterilize, rat, fumigation of grain pests, wood preservation, house layer, ship disinfection, soil and plant seeds disinfection, etc. |
| production method | main raw materials: trinitrophenol, calcium hydroxide and chlorine. Water is added to lime according to a certain proportion to prepare lime mortar, then a certain amount of lime, trinitrophenol and water are mixed to make calcium salt and sent to a chlorination kettle, lime slurry is added, chlorinated for about 2 hours under freezing, the temperature is controlled at 32±1 ℃, then the temperature is cooled to 7±1 ℃, and the chlorination is completed for distillation. |
