Adding a certain compound to certain chemical reactions, such as: 69045-78-9, 2-Chloro-5-(trichloromethyl)pyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 2-Chloro-5-(trichloromethyl)pyridine, blongs to pyridine-derivatives compound. Recommanded Product: 2-Chloro-5-(trichloromethyl)pyridine
2000 kg of 2-chloro-5-trichloromethylpyridine was placed in a glass-lined chlorination kettle.Then adding catalyst to the reactorThe 150kg reactor is heated with a heat transfer oil.When the temperature rises to 130 C, chlorine gas is introduced into the reactor to control the amount of chlorine.The reaction temperature was controlled at 180 C. The reaction time is usually 100 hours.After the reaction is completed, the temperature is lowered to 50 C, and the catalyst is filtered off.After the 2,3-dichloro-5-trichloromethylpyridine was metered, it was fluorinated in a fluorination kettle.
The synthetic route of 69045-78-9 has been constantly updated, and we look forward to future research findings.
