Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] Such as figure 1 As shown, the present invention provides a kind of iodic acid and hydroiodic acid preparation all-in-one device, and it comprises electric redox reactor 2, and electric redox reactor 2 comprises oxidation chamber 211 and reduction chamber 212, and reduction chamber 211 and hydroiodic acid Circulation box 6 links to each other, and oxidation chamber 211 links to each other with iodic acid circulation box 7; When electrifying in electric redox reactor 2, oxidation reaction takes place in oxidation chamber 211, elemental iodine loses electrons to generate iodic acid; Iodine obtains electrons in reduction chamber 212 A reduction reaction takes place to generate hydriodic acid, thereby enabling both iodic acid and hydriodic acid to be obtained simultaneously from the same starting material in different reaction chambers of the same 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 ...
