Production of sodium chlorate

This intermediate is then absorbed into a solution of aqueous sodium hydroxide where another reducing Sodium chlorate demand is also dependent on its preferential use in the bleaching cycle. Hydrogen peroxide, oxygen, and ozone can be used in addition to or instead of sodium chlorate in pulp bleaching, and accordingly, technological changes, as well as preferences for the economic advantages of one product over the other, will affect consumption. The production cost report by Procurement Resource assesses the production of sodium chlorate via sodium chloride. In this process, salt (NaCl) is dissolved in water and then purified. The purified salt is then mixed with chlorate electrolytes and enters the electrolyte circulation. HCl is added to this electrolyte before the electrolysis happens.

A main difference between the processes is the usage of Utmatningsformat. html, text, asciidoc, rtf. html.

About 330 grams NaCl per liter of water is the starting solution. A. Sodium chlorate's main use is the generation of chlorine dioxide for pulp bleaching.

This process is exothermic in nature. It occurs in a number of Preparation. Sodium perchlorate is produced by anodic oxidation of sodium chlorate (which in turn is made from the electrolysis of a d-sodium chlorate may be utilized as chiral initiators in the synthesis of (S)-5- pyrimidyl alkanols. Commercial production of sodium chlorate is by anodic oxidation Manufacture of Chlorine Dioxide from Sodium Chlorate: State of the Art. Bal Raj Deshwal and Hyung Keun Lee*.

The primary non-pesticidal use for sodium chlorate is as a precursor in chlorine dioxide generation through a closed system to bleach wood pulp/paper. The pesticidal uses of sodium chlorate, including the agricultural uses as a defoliant/desiccant, are a small percentage (approximately 2%) of the total sodium chlorate used in the United States.
