Sodium hydroxide (Latin Natrii hydroxidum; other names — the caustic soda, a caustic soda, caustic rubbed, caustic alkali) — the most widespread alkali, a chemical formula NaOH. In a year in the world more than 57 million tons of a caustic natr are made and consumed.
Caustic rubbed is applied in a set of industries and to domestic needs:
The caustic soda is applied in pulp and paper industry to a delignifikation (sulphatic process) of cellulose, in production of paper, a cardboard, artificial fibers, wood and fiber plates.
For saponification of fats by production of soap, shampoo and other detergents. Now products on the basis of sodium hydroxide (with potassium hydroxide addition, heated to 50-60 degrees Celsius, are applied in the sphere of an industrial sink to cleaning of products from stainless steel from fat and other oil substances, and also the machining remains.
In chemical industries — for neutralization of acids and acid oxides, as reagent or the catalyst in chemical reactions, in the chemical analysis for titration, for etching of aluminum and in production of pure metals, in oil processing — for production of oils.
For production of biodiesel fuel — the usual diesel fuel received from vegetable oils and used for replacement. For receiving the biodiesel one mass unit of alcohol (that is the ratio 9:1 is observed), and also the alkaline catalyst (NaOH) is added to nine mass units of vegetable oil.
As the agent for dissolution of blockages of sewer pipes, in the form of dry granules or as a part of gels. Sodium hydroxide disaggregates a blockage and promotes its easy advance further on a pipe.
In civil defense for decontamination and neutralization of toxic agents, including sarin, in rebrizer (the isolating respiratory devices (IRD), for purification of the exhaled air of carbon dioxide.
Sodium hydroxide is also used in combination with zinc for focus.
Sodium hydroxide is also used for a sink of compression molds of tire covers.
Sodium hydroxide is also used for illegal production of metamfetamin and other drugs.
In cooking: for washing and cleaning of fruit and vegetables of a thin skin, in production of chocolate and cocoa, drinks, ice cream, caramel coloring, for a softening of olives and giving of black coloring to them, by production of bakery products. It is registered as a food additive of E524.
In cosmetology for removal of the horny skin sites: warts, papillomas.
