System and method for producing iodine compound

摘要

A system (100) of the present invention for producing an iodine compound includes: a raw material adjusting unit (1) for supplying hydrogen-containing gas to at least one of liquid iodine in an iodine melting pot (4) and gaseous iodine obtained by evaporating liquid iodine so as to obtain a mixture gas; a hydrogen iodide producing unit (10) including a hydrogen iodide producing tower (12) having a catalyst layer (12a) for converting the introduced mixture gas into crude hydrogen iodide gas; a hydrogen iodide refining unit for removing unreacted iodine from the introduced crude hydrogen iodide gas so as to obtain hydrogen iodide gas; and an iodine compound producing unit (30) for producing a target iodine compound from the obtained hydrogen iodide gas and a reaction material. This allows producing an iodine compound with high purity easily, efficiently, and with low cost.
