Embodiment Construction

[0011] refer to figure 1 , make an integrated electrolytic reactor 2, its outside is connected with a cooling jacket 3, its inlet end is connected with the fluorine gas inlet pipe 1, and the iron condenser 5, the left quartz cold trap 6, and the left quartz cold trap 7 are connected through the connecting pipeline 4 constituted as a whole.

[0012] The technology of preparing iodine pentafluoride by directly fluorinating iodine with elemental iodine at room temperature is used to prepare iodine pentafluoride by burning iodine in a fluorine gas flow near room temperature. The outside of which is connected with a drum-shaped iron cylinder with a cooling jacket 3 as an electrolytic reactor 2 . The electrolytic reactor 2 is connected to an iron condenser 5 through a connecting line 4, and then connected to the left quartz cold trap 6 and the left quartz cold trap 7.

[0013] Put elemental iodine into the electrolytic reactor 2, and feed fluorine gas through the fluorine gas inle...

Abstract

The invention discloses a technology for preparing iodine pentafluoride by directly fluorating iodine by elemental iodine. The method is mainly characterized in that: an integrated electrolytic reactor is externally connected with a cooling sleeve; an inlet end of the electrolytic reactor is connected with a fluorine inlet pipe; and an iron condenser, a left quartz cold trap and a right quartz cold trap are connected together through a connection pipe. The technology has reasonable process, ensures simple preparation and solves the problem of environmental pollution during the production of iodine pentafluoride, thereby being an ideal technology for preparing iodine pentafluoride.

Description

Technical field [0001] The invention relates to a synthesis and preparation technology of chemical products, in particular to a technology for preparing iodine pentafluoride by direct iodine fluorination of elemental iodine, which is suitable for chemical synthesis and preparation of iodine pentafluoride. Background technique [0002] At present, the traditional technology is to react iodine and fluorine gas in a negative pressure container. The technical production process is cumbersome, the reaction temperature is unstable during the reaction, continuous production is not possible, there are many by-product emissions, and the single product has the disadvantages of high energy consumption. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a technology for preparing iodine pentafluoride by directly fluorinating iodine with elemental iodine. The technology not only has reasonabl...
