Products Description of Sodium dichloroisocyanurateCAS#2893-78-9

White crystalline powder, with a strong chlorine smell, containing 60% to 64.5% effective chlorine. It is stable. When stored in hot and humid areas, the effective chlorine content only drops by about 1%. It is easily soluble in water, with a solubility of 25% (25°C). The solution is weakly acidic, and the pH of its 1% aqueous solution is 5.8 to 6.0. The pH changes little with increasing concentration. It dissolves in water to produce hypochlorous acid, and its hydrolysis constant is 1×10-4, which is higher than that of chloramine T. The stability of the aqueous solution is poor, and the loss of effective chlorine is accelerated under the action of ultraviolet rays. A low concentration can quickly kill various bacterial propagules, fungi, and viruses, and is particularly effective against hepatitis viruses. It has the characteristics of high chlorine content, strong bactericidal effect, simple process, and low price. Sodium dichloroisocyanurate has low toxicity and better bactericidal effect than bleaching powder and chloramine-T. Chlorine fumigants or acid chlorine fumigants can be made by mixing metal reducing agents or acid synergists with potassium permanganate and sodium dichloroisocyanurate dry powder. This type of fumigant produces a gas with a strong bactericidal effect when ignited.

Product Application of Sodium dichloroisocyanurateCAS#2893-78-9

Sodium dichloroisocyanurate can be used for drinking water disinfection and tableware disinfection; it can also be used for fruit and egg surface disinfection to extend the shelf life; it is widely used in large-scale disinfection for flood control and disaster relief, and preventive disinfection in areas with epidemic infectious diseases; it can be used in silkworm farms and silkworm farmers in the form of fumigation, aqueous solution and powder to disinfect silkworm rooms, silkworm tools and silkworm bodies; it can effectively prevent and treat fish diseases caused by bacteria, fungi and algae, and has obvious effects on fish viral diseases; using 2-3% chloramine aqueous solution and adding other auxiliaries to soak wool or wool blended fibers and fabrics can prevent wool and its products from pilling and shrinking, reaching the super wash-resistant standard promulgated by the International Wool Bureau.
