- a method for simultaneously fluorinating the compounds is disclosed, and it describes that in addition to obtaining the target compound at a high yield, the compound also has a corrosion preventing effect on the reactor.
- a method using a product or an intermediate product as a solvent means that it is necessary to increase the capacity of the reactor by at least the amount of the solvent used. This is not economically advantageous.
- the compatibility with hydrogen fluoride is poor, and the phase separation between hydrogen fluoride and the solvent in the reactor may significantly reduce the reaction efficiency, so that it can be applied only to a limited use.
- the method for simultaneously fluorinating dichloromethane and 1,1,1-trichloromethane in Japanese Unexamined Patent Publication No. 8-217770 is a method of producing unnecessary compounds when only one of them is required. It is economically disadvantageous.

This shows that the concentration of the antimony compound with respect to hydrogen fluoride is approximately 100 mol%.
- the absence of hydrogen fluoride in the reaction solution means that the supply of the fluorine source in the fluorination reaction becomes slow, which is not suitable for performing an efficient reaction.
- a method using a fluorine resin reactor is disclosed in Japanese Patent Application Laid-Open No. 7-233102, and a method for reducing the water content in the raw material is described in Japanese Patent Publication No. 7-85859. Methods of reducing corrosiveness by preserving each are disclosed.
