Description

Chlorine dioxide is a yellow to reddish-yellow gas that can decompose rapidly in air. Because it is a hazardous gas, chlorine dioxide is always made at the location where it is used. Chlorine dioxide is used as a bleach at pulp mills, which make paper and paper products, and in public water-treatment facilities, to make water safe for drinking. It has also been used to decontaminate public buildings. Chlorine dioxide is soluble in water and will react rapidly with other compounds.

Chlorine dioxide Use and Manufacturing

Methods of Manufacturing

Chlorine dioxide is manufactured from the oxidation of chlorite or the reduction of chlorate. The latter method is used for large-volume production and is carried out in strongly acidic solution using reducing agents such as NaCl, HCl, sulfur dioxide, and methanol.

Uses

Chlorine dioxide is used for several purposes,including its applications as a bleachingagent to bleach fats, oils, textiles, cellulose,paper pulp, flour, and leather. It is also usedfor purifying water; as an oxidizing agent;as an antiseptic; and in the manufacture ofmany chlorite salts.
Bleaching cellulose, paper-pulp, flour, leather, fats and oils, textiles, beeswax; purification of water; taste and odor control of water; cleaning and detanning leather; manufacture of chlorite salts; oxidizing agent; bactericide, antiseptic and deodorizer.
Chlorine Dioxide is a gas used in bleaching and aging flour. it acts on the flour almost instantly, resulting in improved color and dough properties. because usage levels are low, the bleaching action is limited.
