Calcium hypochlorite CAS 7778-54-3 Water Purification Chemicals
Bleaching powder is calcium hydroxide, calcium chloride, calcium hypochlorite mixture, its main component is calcium hypochlorite [Ca(ClO)], effective chlorine content of 30%-38%.Bleaching powder is white or off-white powder or granule, with obvious chlorine stink, very unstable, strong hygroscopicity, and easy to be decomposed by light, heat, water and ethanol.Bleach is dissolved in water in a solution that causes the litmus paper to turn blue, then fade and turn white.Carbon dioxide in the air can be free hypochlorous acid, rare hydrochloric acid will produce a lot of chlorine gas.
Bleach is made by reacting chlorine gas with calcium hydroxide (hydrated lime).Because absolutely dry calcium hydroxide does not react with chlorine gas, chlorine can only be adsorbed by calcium hydroxide.Therefore, in industry, hydrated lime containing less than 1% free water is used for chlorination, and the chlorine gas used also contains less than 0.06% water.The free water in these raw materials is used to hydrolyze chlorine gas to produce acid (HClO, HCl), and the resulting acid is neutralized by hydrated lime.Then, depending on the water precipitated from calcium hydroxide during the chlorination reaction, the chlorine will continue to be hydrolyzed, and more calcium hydroxide will be involved in the reaction process to generate a series of compounds.Bleach is a complex of these compounds.

China's food industry widely USES bleach as a disinfectant, low price, strong sterilization, disinfection effect.If be used at the disinfection of drinking water and fruit vegetable, still often use at the establishment such as swimming pool, bathroom, furniture and article disinfection, also often use at the bleaching such as food of fat, starch, fruit skin in addition.It can also be used for deodorization and decolorization of wastewater.In food production is generally used in the absence of grease and equipment disinfection.If work station, wall, ground, cooling pool, carriage car, working galoshes.
