摘要：Provided is a method for easily and safely removing, from a reactor, a catalystused in a reaction that is performed using hydrogen fluoride in the presence of thecatalyst. In a reaction performed in a reactor containing at least hydrogen fluoride and acatalyst, the catalyst is removed through a process comprising a heating step ofperforming heat-treatment so that the ambient temperature of the reactor is 80°C ormore after completion of the reaction, and a purge step of flowing inert gas into thereactor to discharge the hydrogen fluoride to the outside of the reactor aftercompletion of the reaction.
