| titleOfInvention | The synthesis technique of N, N-dimethyl-N-phenyl-(N-fluorine dichloromethane sulfenyl)-sulphonamide |
| abstract | The invention discloses a kind of N, the synthesis technique of N-dimethyl-N-phenyl-(N-fluorine dichloromethane sulfenyl)-sulphonamide, this synthesis technique adopts ferric fluoride to do fluorochemical, with the toluene solution of fluorine dichloromethyl sulfuryl chloride and N, N-dimethyl-N '-phenyl-sulfamide obtains N, N-dimethyl-N-phenyl-(N-fluorine dichloromethane sulfenyl)-sulphonamide after recrystallization under certain reaction conditions.The first synthetic intermediate of this synthesis technique, utilization ratio and the yield of intermediate can be improved in the preparation link of intermediate, and reacted surplus materials is convenient to recycle, greatly cost-saving and reduce environmental pollution, in intermediate building-up process, adopt ferric fluoride to not only increase N as fluorochemical, the yield of N-dimethyl-N-phenyl-(N-fluorine dichloromethane sulfenyl)-sulphonamide, and it is little to environmental influence, solve existing method raw materials cost high, " three wastes " that produce are large to environmental hazard, yield is very low and unstable and cause N, N-dimethyl-N-phenyl-(N-fluorine dichloromethane sulfenyl)-sulphonamide is difficult to the problems such as suitability for industrialized production. |
