N-[4-(trichloromethylthio)sulfonylphenyl]acetamide - Preparation Method
Open Data Verified Data
- 3 the diazotization process of monochloro-4-fluoroaniline is mature, the product quality is good, but the price is high, so it is only used for laboratory synthesis.
- 2,4-= Nitro fluorobenzene chloride method this method is the main production method of 2,4 one two chlorine fluorobenzene, the lowest cost, the best economic benefit.
- chlorination of 3 chloro -4 fluoronitrobenzene the conversion of 3-chloro-4-fluoronitrobenzene was 95%, and the selectivity to 2,4-= chlorofluorobenzene was 90%. If nitric acid chloride is used instead of chlorine in the reaction, the selectivity can be increased to 94.3%.
- 5 monochloro-2-fluoronitrobenzene chlorination the yield of the product was 74.5%.
