Iodic acid and hydroiodic acid preparation all-in-one machine device

Abstract

The invention relates to an iodic acid and hydroiodic acid preparation all-in-one machine device, and relates to the technical field of chemical engineering. The iodic acid and hydroiodic acid preparation all-in-one machine device is used for solving the technical problems that the processing efficiency is hot high in the prior art. The iodic acid and hydroiodic acid preparation all-in-one machinedevice comprises an electrooxidation reduction reactor, by adopting the same raw material and the same device, namely, elemental iodine is adopted to simultaneously obtain iodic acid and hydroiodic acid, an oxidation reaction occurs in an oxidizing chamber of the electrooxidation reduction reactor to generate the iodic acid, a reduction reaction occurs in a reduction chamber of the electrooxidation reduction reactor to generate the hydroiodic acid, a reaction endpoint is controlled by an electric potential in the whole process, the preparation purity is high, concentration is high, no dangerous and waste liquid generates, and more environmental protection is achieved.

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 ...

Problems solved by technology

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 waste

The above-mentioned method for preparing iodic acid and hydroiodic acid cannot be carried out simultaneously through a set of equipment using the same raw material, and the above-mentioned method will produce waste liquid, which is not conducive to environmental protection
