Seeking information on the working principle of vanadium-chromium series catalysts used in chlorothalonil production
Thread Content
Newcomer to the workplace, seeking advice from those with more experience: The raw material used in our factory for chlorothalonil is m-xylene, which reacts with ammonia and oxygen under the action of vanadium-chromium catalysts to produce m-phenylenedinitrile. What exactly is the catalyst used in this process? Is silica gel used as a carrier? What is its mechanism of action, and what are its parameters? Can it become poisoned? Finally, I would like to know what are the most common process problems that arise during the production of chlorothalonil. First, I’d like to thank all the seniors
Hello, may I ask what the name of your factory is? I am in the business of m-xylene
Alumina is used as the carrier, with vanadium as the active center. For process issues, it depends on how mature your processes are.
