About Sodium Hypochlorite. Sodium Hypochlorite (a.k.a. Liquid Bleach, NaOCl) is the active constituent in chlorine bleach, a strong oxidizer and bleaching agent. This salt is the most remarkable of all hypochlorite forms and has been widely used since the 1930s. Nowadays, it is the most used hypochlorite bleach, accounting for more than 90% of global use, while calcium hypochlorite corresponds to the remainder.
It is an industrial practice to establish definitions of sodium hypochlorite strength in order to characterize the product. The term “available chlorine” is often used and is a measure of the oxidizing capacity of a chemical relative to that of pure Cl2. Sodium hypochlorite contains about 95.3 wt.% of available chlorine. From this definition, a common term used is “trade percent of available chlorine” which expresses the weight of available chlorine in grams per 100 mL of NaClO solution. Additionally, strength can be simply measured as the weight percent of sodium hypochlorite in solution.
Sodium hypochlorite is mainly produced through chlorine contact with diluted caustic soda (NaOH). The process is similar to that used for preventing chlorine emissions in chlor-alkali plants (chlorine scrubbing).
Sodium Hypochlorite solutions should be stored at a temperature below 15 °C, away from acids, and protected from direct sunlight. The storage system should also be vented to avoid oxygen off-gassing of this chemical. For industrial purposes, fiberglass reinforced plastic, chlorobutyl rubber-lined, and polyethylene tanks are preferred to store Sodium Hypochlorite solutions. Steel tanks should be avoided because they tend to degrade in contact with bleach. For bulk supply, transportation is usually done by tank trucks. For small quantities, Sodium Hypochlorite solutions are transported by containers (500 mL to 20 L).
Bleach may be produced by batch or continuous process, depending on its particular use or market demand. Two main types of manufacturing processes can be distinguished: chemical production and electrochemical production. Raw materials and the respective production processes employed in the manufacturing of Sodium Hypochlorite are listed below.
- Sodium chlorate + sulfuric acid + refined sodium chloride (Erco R3 process; byproduct of chlorine dioxide production),
- Sodium hydroxide + chlorine (reaction)
The uses and applications of Sodium Hypochlorite may vary according to its specification. The main forms of Sodium Hypochlorite are technical grade; household grade (5 to 6 wt% purity); and industrial grade (10 to 15 wt% purity).
Sodium hypochlorite is an excellent disinfecting agent that is used in water treatment; cleaning and laundry operations; clinics and hospitals; and at residences for disinfecting kitchen and bathroom surfaces.
