Manufacturing of Bleaching Powder. Profitable Chemical Business Ideas for Entrepreneurs.
Bleaching powder is extensively used as a chlorine compound that is highly effective against several microorganisms such as algae, bacteria, fungi, slime and other harmful and unwanted micro-organisms which exist in the environment. The market is primarily driven by its use in swimming pools, hot tub water and spas. It’s utilized in the swimming pools to kill thriving microorganisms that create a threat to human health and conjointly to prevent contamination.
Strong solutions of bleaching powder are used to clean and sanitize pool sides, pool bottom, diving boards, decks, ladders and different surfaces. It’s also extensively used to treat waste water and clean sewages. It usually used as a bleaching agent and also finds application as industrial sanitizer.

Uses of Bleaching Powder
Ø It is used for bleaching dirty clothes in the laundry, as a bleaching agent for cotton and linen in the textile industry.
Ø It is a strong oxidizing agent hence used as an oxidizer in many industries.
Ø It is used as a disinfectant which is used for disinfecting water to make potable water.
Ø It is used for bleaching silk and wool.
Ø It is mainly used as bleaching agent for cotton, linen and wood pulp.
Ø Bleaching action of bleaching powder is due to oxidation and it is permanent.
Ø Bleaching powder is used as disinfectant and germicide especially in the sterilization of drinking water.
Ø It is used for manufacturing of chloroform.
Ø It is used as an oxidizing agent in many chemical industries to obtain various chemical products.
Preparation of Bleaching Powder Reaction
Bleaching powder is prepared on an outsized scale by passing the chlorine gas through an answer that contains calcium hydroxide. Bleaching powder is also sold-out on the basis of the on the market chlorine, that is liberated once it's treated with the dilute acid. Bleaching powder is used for bleaching paper pulps and fabrics and for sterilizing water.
Calcium hypochlorite is used as a bleaching agent and disinfectant agent. The bleaching powder is also known as chlorinated lime (chloride of lime) that is used in error within the whitewash. Bleaching powder also causes irritation on the skin and eye.

Applications
• Bleaching powder is used for bleaching cotton and linen in textile industry.
• Bleaching wood pulp in paper industry.
• It is also used for bleaching washed clothes in laundry. The bleaching action of bleaching powder is due to the chlorine released by it.
• Bleaching powder is used for disinfecting drinking water supply. That is, for making drinking water free from germs.
• Bleaching powder is used for the manufacture of chloroform (CHCl).
• Bleaching powder is used as an oxidizing agent in many chemical industries.
• Waste Water Treatment and Sewage disposal.
• Household Bleaching/Cleaning applications.
• Used as a Sanitizing Agent also.
Characteristics of bleaching powder
• Bleaching powder is a pale yellowish powder existing with a strong smell of chlorine.
• It is soluble in water but due to the presence of impurities.
• Its chemical formula is CaOCl2 with its chemical name as Calcium hypochlorite.
Advantages:-
Peroxide may be a universal bleaching agent and may be used for wool, silk as well as cotton. It’s especially suited to the bleaching of union fabrics containing each cotton and wool or silk.
Hydrogen peroxide may be a milder reagent than salt and therefore the degrading effect of peroxide bleaching on cellulose is less influenced than is that the case with hypochlorite.
Peroxide is capable of continuous the scouring action simultaneously with the bleaching action, therefore a single stage combined scour and bleach or a continuous method is feasible using hydrogen peroxide.
Peroxide bleaching is generally less prone to have adverse impact on dyed threads. The white impact is good and permanent and there's less risk of yellowing at a later stage.
Thorough rinsing followed by scouring or antichlor treatment is required with hypochlorite bleaching, whereas with peroxide a comparatively short rinsing suffices.
With hydrogen peroxide, there's no danger of equipment corrosion, no unpleasant odors and no limitations on processing techniques.
Increasing strict control over the discharge of AOX from chlorine bleaching liquors has led to a greater advantage of peroxide processes for bleaching cellulosic fibres.
