Description

technical field

[0001] The invention relates to the technical field of chemical industry, in particular to an all-in-one device for preparing iodic acid and hydroiodic acid. Background technique

[0002] Hydroiodic acid is an aqueous solution of hydrogen iodide. It has a strong irritating sour taste. It is a strong acid and is the most acidic among non-radioactive anaerobic acids. It is easily oxidized in the air and releases free iodine. the strongest. In the prior art, the disclosure of the preparation of hydriodic acid mostly uses phosphorus to produce hydriodic acid. The method yield is general, the concentration is low, the purity is poor, and waste liquid will be produced; the industrial preparation of iodic acid generally utilizes iodine Elemental substances can undergo disproportionation reaction in alkaline aqueous solution to prepare iodate, and then separate iodide from iodate and acidify to obtain iodic acid, which has low purity and will also produce hazardous ...
