Abstract
According to a method for producing an inorganic iodide in accordance with the present invention, it is possible to efficiently produce a highly pure inorganic iodide by reacting a hydrogen iodide gas with an inorganic base compound by bringing the hydrogen iodide gas into contact with the inorganic base compound. As such, it is possible to provide a simple and efficient method for producing an inorganic iodide.
Claims6
A method for producing an inorganic iodide, comprising the step of:
- a) contacting a saturated hydrogen iodide solution with crude hydrogen iodide gas comprising iodine gas and hydrogen iodide gas, wherein the contacting results in separation of the iodine gas from the hydrogen iodide gas,
- b) collecting the hydrogen iodide gas separated from the iodine gas, the collected hydrogen iodide gas containing iodine molecules by not more than 2 wt % with respect to a total weight, of the hydrogen iodide gas, which is 100 wt %,
- c) reacting the collected hydrogen iodide gas with an inorganic base compound by bringing the hydrogen iodide gas into contact with the inorganic base compound, wherein said reacting results in production of an inorganic iodide.
