Description
An orange, unstable gas with a strong chlorine odor. Chlorine dioxide was introduced in 1951 for use in bleaching wood pulp, paper, leather, textiles, waxes, fats, oils, and flour. Chlorine dioxide can be used in gas phase as well as in an aqueous solution (2% or less). It is also used as a bactericide and deodorizer.
Synonyms and Related Terms
chlorine peroxide; chlorine oxide; anthium dioxide; chlorine (IV) oxide; chloroperoxyl; chloryl radical; alcide;
