METHOD FOR PRODUCING HYDRIODIC ACID AND METHOD FOR PRODUCING AQUEOUS METAL IODIDE SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing hydriodic acid that attains a high yield, has an easy operation, suppresses the production cost and imposes a low environmental load.;SOLUTION: A method for producing hydriodic acid comprises a reaction step of heat-treating an aqueous solution comprising formic acid and iodine with the concentration of iodine and iodide ions in total accounting for 1 to 22.5 mass% to give hydriodic acid.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
