Sodium Hydroxide application and storage

Sodium Hydroxide application and storage

Sodium hydroxide, also known as Caustic Soda, is a solid, white mineral with the chemical formula NaOH, with a melting point of 318 ° C and a density of 2.13. This material can easily absorb moisture and carbon dioxide in the air and therefore, Sodium hydroxide to be under the necessary protective cover during transportation. Sodium hydroxide also generates a lot of heat when dissolved in water. This compound, in contact with the skin, has a corrosive effect and should be considered when using it to prevent its irritating effects. Also, when measuring the exact weight of Sodium hydroxide, this should be done quickly and in a dry environment so that the weight of sodium hydroxide does not increase due to the absorption of air moisture. Sodium hydroxide sealants are known to form strong alkaline solutions in water, meaning that they are completely separated from their constituent Na + and OH- ions in water. Solid sodium hydroxide is mostly sold in the form of flakes, granules and mold blocks.

Sodium hydroxide History

Sodium hydroxide was originally produced by soap makers. Instructions for making sodium hydroxide by a 13th-century Muslim scholar Al-Mukhtarah are found in the book Fi Fiunoon Man Al-Sunnah, compiled by Al-Muzaffar Yusuf Ibn Umar Ibn Ali Ibn Rasool, King of Yemen. The English chemist and archaeologist Henry Ernst Stapleton (1878–1962) provided evidence that Muhammad Zakaria Razi knew sodium hydroxide. This instruction involved passing successive amounts of water through a mixture of alkali containing Saltwort ash grass ash and crude lime to obtain sodium hydroxide. European soap makers followed the same instructions.

Sodium hydroxide Application

Sodium hydroxide uses of solid caustic soda is in the production of paper. Basically, pulp is produced in two ways, mechanical and chemical. Sodium hydroxide should be noted that the mechanical method is commonly used to produce inexpensive papers. In chemical methods of pulp preparation, solid caustic soda (sodium hydroxide) and sodium sulfite or calcium hydrogen sulfite are usually used and the raw materials of paper making are processed (baked) by caustic soda and sodium sulfide. Application of Sodium hydroxide in the aluminum industry is used to dissolve bauxite ore, which is the raw material for aluminum production, and alumina deposition. Sodium hydroxide is also used to chemically brighten aluminum products. In the soap industry, Sodium hydroxide is converted to fats in water-soluble sodium soaps (soap making process) in the textile industry, Is used. If we want to use Sodium hydroxide in the oil production process and refining industry, we can use the role of Sodium hydroxide as an adsorbent of carbon dioxide in light sections and as an adsorbent of sulfides in the purification of various oil sections. He also mentioned Sodium hydroxide along with chlorine for the hypochlorite sweetening process, which is a process for removing various sulfur compounds. Sodium hydroxide, as a strong base, is one of the most important industrial chemicals. For example, profit generation in the United States in 1980 was 12 million tons. Production of this basic chemical; Which is used in the production of all types of chemicals, increased from 60390 kilotons in 2012 to 72103 kilotons in 2016, which is an average growth of 4.53 percent. China is the world’s largest profit maker of Sodium hydroxide, accounting for 45.55% of the market share in the sodium hydroxide industry in 2016. In the consumer market, China and North America are the main consumers of this substance, which is estimated to have consumed 42.79% and 20.29% in 2016, respectively. Various fields of application of sodium hydroxide, including in the production of chemicals, rayon, pulp and paper, in the production of paints, aluminum, petrochemicals and textiles, soaps and detergents. Standard alkaline sodium hydroxide solution is also used in laboratories to determine the concentration of unknown acids in open acid titration. In the food industry, this substance is used to remove bitterness from olives. Sodium hydroxide is produced in factories in both liquid and solid forms. Liquid sodium hydroxide is available in 50% and 33% purity. The applications of sodium hydroxide flakes are very wide in industry; different industries use this material with different approaches. Some of these industries are:

Sodium hydroxide in Dyeing industries.

Sodium hydroxide, in Production of cartons and paper.

Sodium hydroxide in Leather and textile industries.

Sodium hydroxide in Oil and gas and petrochemical industries.

Sodium hydroxide in Acid neutralization and battery production.

Sodium hydroxide in Fat burners and other related industries.

 Sodium hydroxide in Food industry, dairy industry, canning.

Sodium hydroxide in Beverage factory, sugar factory, oil factory.

Sodium hydroxide in Pharmaceutical, alcohol and cosmetics industries.

Sodium hydroxide in Metal industry and production of zinc glass, aluminum, galvanized and plating.

Sodium hydroxide used in the oil and gas industry.

Sodium hydroxide used in the military industry.

Sodium hydroxide  used for industries that are exposed to pathogens.

Sodium hydroxide Storage conditions and safety tips

Sodium hydroxide solution can easily break down proteins and fats in living tissues through amide hydrolysis and ester hydrolysis, resulting in chemical burns and possibly permanent blindness. Make eye contact. Sodium hydroxide solid alkali can also show its corrosive nature in the presence of water, such as water vapor; Therefore, when using these chemicals or their solutions, protective equipment such as rubber gloves, safety clothing and eye protection should always be used. The basic standard procedure for rinsing Sodium hydroxide substance from the skin, like other corrosives, is to rinse with plenty of water. Washing should continue for at least 10 to 15 minutes.

In addition, the dissolution of sodium hydroxide is very hot, and the resulting heat can cause heat burns or flammable materials. Sodium hydroxide also generates heat when it reacts with acid.

Sodium hydroxide is also slightly corrosive to glass, which can damage its transparency or lock glass junctions together. Sodium hydroxide is also corrosive to many metals, such as aluminum, which reacts with alkali to produce flammable hydrogen gas at the contact surface.
