A method for producing a fluorinated halogen compound, which comprises reacting with the halogen of fluorinated halogen.
(2) After fluorinated halogen is added to the fluorinated gas stream to evaporate and mix, it is introduced into a reactor heated to a temperature higher than the reaction temperature of fluorinated gas and fluorinated halogen, and fluorinated gas and fluorinated halogen are combined. A method for producing a fluorinated halogen compound, which comprises reacting.
(3) After adding a halogen other than fluorine and a fluorinated halogen to the fluorine gas stream, evaporating and mixing them, the reactor is heated to a temperature equal to or higher than the reaction temperature of the fluorine gas and the halogen other than fluorine and the fluorinated halogen. A method for producing a fluorinated halogen compound, which is introduced and is characterized by reacting fluorine gas with a halogen other than fluorine and a fluorinated halogen.
(4) The method for producing a fluorinated halogen compound according to (1) above, wherein the halogen other than fluorine is chlorine, and the fluorinated halogen compound is chlorine monofluoride or chlorine trifluoride.
(5) The method for producing a fluorinated halogen compound according to (1) above, wherein the halogen other than fluorine is bromine and the fluorinated halogen compound is bromine pentafluoride.
(6) The method for producing a fluorinated halogen compound according to (1) above, wherein the halogen other than fluorine is iodine and the fluorinated halogen compound is iodine heptafluoride.
(7) The method for producing a fluorinated halogen compound according to (2) above, wherein the fluorinated halogen is chlorine monofluoride and the fluorinated halogen compound is chlorine trifluoride.
(8) The method for producing a fluorinated halogen compound according to (2) above, wherein the fluorinated halogen is bromine trifluoride and the fluorinated halogen compound is bromine pentafluoride.
(9) The method for producing a fluorinated halogen compound according to (2) above, wherein the fluorinated halogen is iodine pentafluoride and the fluorinated halogen compound is iodine heptafluoride.
(10) The linear velocity of fluorine gas in the evaporator is 30 cm / sec. Or less, and the gas linear velocity in the reactor is 10 cm / sec. Or less. 3) The method for producing a fluorinated halogen compound according to the above method.
In the present invention, a reaction raw material such as iodine pentafluoride is added to a fluorine gas stream that flows gently and is heated to near the boiling point of the raw material (halogen element other than fluorine or fluorinated halogen), and after evaporation and mixing. By introducing these gases into a high-temperature reactor and reacting them, a target product such as iodine pentafluoride can be efficiently and continuously obtained. As a result, the temperature of the mixed portion of the raw material and the fluorine gas can be suppressed to about the boiling point of the raw material (100 to 130 ° C.), and the corrosion of the mixed portion can be significantly reduced. In addition, it is possible to prevent an explosive reaction by separating the mixing part and the reaction part of the raw material and the fluorine gas, and supplying the reactor with a stoichiometric amount of the raw material that has been sufficiently agitated / mixed and gently heated. it can.
