chemical properties



hypochlorite in aqueous sodium hypochlorite can decompose quite quickly - but the chemical decomposition reaction will depend on the temperature of the water and its pH.Strongly acidic solution fully hydrolyzed hypochlorites, expanding them at room temperature to oxygen and chlorine.Neutral environment turns hypochlorite to chlorate and chloride - thus slowing the reaction at room temperature and accelerated by its increasing.Temperatures above 70 ° C significantly accelerates the decomposition process and is used in industry to produce chlorate.

Hypochlorites are strong oxidizing agents, but their oxidizing ability in aqueous solution are strongly dependent on its pH environment.

hypochlorite placed in the alkaline solution reacts with hydrogen peroxide, forming chloride and oxygen.The main feature of this reaction in the release of oxygen in the excited singlet state and not the triplet.It also is a prerequisite for its high activity and fosforestsirovaniya near infrared.

Application hypochlorite



in organic synthesis alkilgipohlority subjected to thermal or photochemical isomerization to obtain δ-chlorohydrins.Upon reaction Hoffmann carboxylic acid amides react with the hypochlorites and grouped within the molecules into isocyanates subsequently hydrolyzed to the primary amines or urethanes formed (in the presence of alcohol).

first hypochlorite, which began to be used in the industry, was a potassium hypochlorite, is applied in the bleaching of pulp tissue.

calcium hypochlorite and sodium - a large-products which are prepared by passing chlorine through a suspension or solution of the corresponding hydroxide.Most of the hypochlorite produced by this method is used in a mixture with a specific chloride - for example, hypochlorite mixed with calcium chloride, is transformed into the output bleach.

low cost and strong oxidizing properties allow the use of hypochlorite as a bleaching agent in paper, textile and pulp industry.Furthermore, they are used for decontamination of organophosphorus and sulfur-containing noxious substances, as well as for chemical disinfection of drinking water and sewage.
