Chlorate candles store oxygen for breathing emergencies. But rather than store it as a gas, oxygen in a chlorate candle is locked up in the form of a solid chemical compound, sodium chlorate, NaClO 3. In that form, the oxygen is very stable and easy to store: chlorate candles may last for many years. Chlorate Candles: Chemistry to the Rescue This paper presents a novel cleaner production process for producing sodium chlorite by reducing sodium chlorate with hydrogen peroxide.

Full capacity is expected to be achieved by the end of the year. The new production line is based on Kemira’s proprietary in-house technology and it will significantly increase Joutseno site’s current sodium chlorate capacity. Sodium chlorate is the raw material used to produce chlorine dioxide gas of use when dissolved in water for the bleaching of pulp. When used for the production of chlorine dioxide the sodium chlorate is reacted commonly with sulphuric acid to produce chlorine dioxide, chlorine and sodium sulphate. Usually a pH of about in the feed is satisfactory. The feed to the cell comprises 1080 pounds per hour of sodium chlorate, 640.

Purified brine is acidified with hydrochloric acid and sodium dichromate is added to improve cell efficiency and reduce electrode corrosion. The acidified brine is fed to a bank of electrolytic cells. production sodium chlorate chlorate sodium Prior art date 1986-03-27 Application number PT8457087A Other languages Portuguese (pt) Other versions PT84570B (en Inventor John E Burkell Ian H Warren Original Assignee Canadian Ind Priority date (The priority date is an assumption and is not a legal conclusion.

The manufacturing process involves the electrolysis of an acidified sodium chloride solution in a specially designed electrochemical cell. Sodium chlorate is the raw material for chlorine dioxide (ClO2), which is produced on-site at the pulp mills and it is the primary bleaching agent for kraft pulp.

Although chlorine-dioxide can be produced from acid solutions of either sodium chlorite (Deshwal et al., 2004a, Deshwal and Lee, 2005a, White et al., 1942) or sodium chlorate (Ni and Wang, 1997

14. Table 3.4 Waste Management Summary Sodium perchlorate is manufactured electrolytically from sodium chlorate, which is manufactured from brine in the electrolysis process. Manufacture of sodium Chlorine dioxide can be produced from sodium chlorate using different reducing agents like hydrogen peroxide, sulfur dioxide, methanol, and hydrochloric acid. The starting material is NaCl (Sodium Chloride or common salt). Sodium Chlorate is very soluble. About 330 grams NaCl per liter of water is the starting solution.

Sodium chlorite is derived indirectly from sodium chlorate, NaClO 3. First, sodium chlorate is reduced to chlorine dioxide, typically in a strong acid solution using reducing agents such as sodium sulfite, sulfur dioxide, or hydrochloric acid. This intermediate is then absorbed into a solution of aqueous sodium hydroxide where another reducing
