FIELD: chemistry.
SUBSTANCE: invention relates to technology of iodic acid salts production. The invention will find application in chemical, pharmaceutical and food industries in manufacturing of iodine-containing compounds. The method consists in the following. To produce iodic acid, initial agents shall be as follows: hydroiodic acid solution or metal iodide solution, and iodine dissolved in solution of hydroiodic acid or in solution of metal iodide. A solution of iodide or iodide with iodine is dosed into a solution of iodic acid, simultaneously hydrogen peroxide solution is dosed into iodic acid solution. Iodine produced in the solution immediately reacts with hydrogen peroxide, which eliminates formation of crystalline phase of iodine, increases speed of reaction between iodine and hydrogen peroxide, practically eliminates iodine expenses due to sublimation and reduces spontaneous decay of hydrogen peroxide. From the produced solution they crystallise a target product, separate it from mother solution and dry.
EFFECT: proposal of improved technology of iodic acid salts production.
