high purity Sodium hydroxide

 

1.Description

Sodium Hydroxide (NaOH), also known as Iye and caustic soda, is a caustic metallic base. It is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. Worldwide production in 1998 was around 45 million tonnes. Sodium hydroxide is a common base in chemical laboratories.

Pure sodium hydroxide is a white solid,available in pellets, flakes , granules and as a 50% saturated solution. It is hygroscopic and readily absorbs water from the air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat. It also dissolves in ethanol and methanol, though it exhibits lower solubility in these solvents than does potassium hydroxide. Molten sodium hydroxide is also a strong base, but the high temperature required limits applications. It is insoluble in ether and other non-polar solvents. A sodium hydroxide solution will leave a yellow stain on fabric and paper.

Pure anhydrous sodium hydroxide is white translucent, crystalline solid. It was strongly alkaline aqueous solution with alkali all perforating. Purely solid caustic soda is white, there is massive, flakes, solid, and granular. 

2.Application

The use of sodium hydroxide and alkaline desiccant, paper, aluminum smelting, refining tungsten, rayon and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceutical and organic intermediates, old rubber regeneration system of metallic sodium, water electrolysis, as well as inorganic salt production, preparation of borax, chromium salt, potassium permanganate, phosphate, etc., but also the use of many of caustic soda

  3.Handling and Storage

Handling: Handle sealed. Handling personnel should be expert cultivated and following the rules restrict. Proposed operating officer wearing hoods electric air-purifying respirators and dust, corrosion resistance to wear rubber suits, wearing rubber gloves corrosion resistance. Keep a long distance to flammable and combustible. Avoid dust and touch with acid. Loading and discharge tightly, keep the package in good condition.

Storage: Store in cool, dry conditions in cool
