Caustic Soda Flake specification:
Caustic Soda Flake also known as sodium hydroxide flakes. Flake mass is white color, very hygroscopic, also very soluble in water and alcohol. The formula is NaOH. Technical sodium hydroxide flakes are obtained by evaporating of liquid caustic soda А grade.
NaOH also used in organic synthesis processes, petroleum products refining, textile industry in production of viscose silk and in bleaching fabrics It uses in paper and aniline industry, soap making, aluminum and sodium metal production, soluble glass, alkaline accumulators also in Trilon B.
Sodium hydroxide widely uses in large scale usages such as pulp and paper manufacturing, in production of soap and detergents as well as in water treatment plants. It is used in Bayer process of aluminum manufacture as well as to remove sulfurous impurities from crude oil. NaOH also used in manufacture of biodiesel, rayon and cellophane; as a catalyst for the trans esterification of methanol and triglycerides and as paint stripper on wooden objects.
It mainly used for pH control, acid neutralization, off-gas scrubbing and as a catalyst in various industries like pharmaceutical, metal degreasing, agrochemical, dyes, paints and polymer. It is also used in refining vegetable oils, rubber reclamation, metal processing, disinfectants, adhesive preparations, paint removers, rubber latex stabilizers and in stabilization of sodium hypochlorite.
Caustic Soda uses:
Caustic soda flake , sodium hydroxide, mostly used by industry and chemical manufacturing companies. Some fields caustic soda use for :
- Soaps and cleaners
- Refineries Alumina
- plastic wrap
- Water treatment
- Textile processing
- Oil refining
- Metal processing
In addition, major users of caustic soda are the aluminum industry, pulp & paper and the chemical industry. Also main usage in water treatment and water purification, as cleaning agent, or a wide range of uses in chemical industry like starch production or for the desulphurization in the petrochemical industry.
Sodium hydroxide (NaOH) also is solution in water. Furthermore Caustic soda is a strong base with a wide range of applications in different industries. We produce caustic soda together with chlorine and hydrogen from the electrolysis of salt brine.
NaOH also produced as a 50% solution by variations of electrolytic chloralkali process. Cl gas also produced. Solid NaOH is got from this solution by evaporation of water. It`s mostly include as flakes, prills, and cast blocks.
It was produced by causticizing. Treating sodium carbonate with calcium hydroxide in a metathesis reaction. Sodium hydroxide is soluble while calcium carbonate is not.
Ca(OH)2(aq) + Na2CO3(s) → CaCO3 ↓ + 2 NaOH(aq)
This process also was superseded by Solvay process in 19th century. That was in turn put by chloralkali process which we use today.
Caustic Soda In addition produced by combining pure sodium metal with water. Furthermore, by products are hydrogen gas and heat, often resulting in a flame, making this a common demonstration of the reactivity of alkali metals in academic environments. Na isolates by decline electrolysis of sodium compounds including NaOH. However this process is not economic.
The monohydrate crystallizes in space group Pbca, with cell dimensions a = 1.1825, b = 0.6213, c = 0.6069 nm.
Atoms arranged in hydrargillite-like layer structure. /O Na O O Na O/… In addition, <Na> is surrounded by six O2. Three each from hydroxyl anions HO− . Also 3 from water molecules. H2 atoms of hydroxyls form strong bonds with oxygen atoms within each O layer.
