CAUSTIC SODA (NaOH)

Caustic Soda (NaOH)

NaOH was first collected by soap makers.Soap making recipe,noted in an Arab book (13th century) that compiled by king of Yemen.
The recipe was for passing water oft by a mixture of soda or in Arabic alkali. Soda ash got from salt-wort plants because this planets are rich in sodium. Sodium alkali specially was impure sodium carbonate and quicklime (Calcium Oxide, CaO). This process was generate a solution of sodium hydroxide that also called Caustic Soda. In addition, European soap makers followed this recipe. In 1791 Nicolas Leblanc (the French chemist and surgeon), patented a process for mass-producing sodium carbonate, natural “soda ash” .

By the 20th century, the electrolysis of sodium chloride had become one of mostly method for producing NaOH.

What is Caustic Soda ?
Sodium Hydroxide, also known as lye and Caustic Soda, is an inorganic compound with the formula NaOH. Sodium Hydroxide Flakes are white solid ionic compound consisting of sodium cations Na , also hydroxide anions OH−
This flakes are highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. Furthermore It`s highly soluble in water, and readily absorbs moisture and carbon dioxide from the air.

It forms a series of hydrates NaOH·NH2O. The mono-hydrate NaOH·H2O crystallizes from water solutions between 12.3 and 61.8 °C. The commercially available “sodium hydroxide” is often this mono-hydrate, and published data may refer to it instead of the anhydrous compound. As simple hydroxides, employs beside neutral water and hydro-chloric acid to demonstrate the pH.

(NaOH) is known as caustic soda or lye, is a highly versatile substance used in variety of manufacturing processes. Sodium hydroxide is co-product of chlorine production. Its main type is caustic soda flake.

Industrial NaOH produced as a 50% solution by variations of the electrolytic chlor-alkali process. Finally Chlorine gas is the last product. In addition solid NaOH get by vaporation of water of solution. Solid sodium hydroxide is most commonly sold as flakes, prills, cast blocks and lye.

General Information Description
At room temperature, anhydrous sodium hydroxide is a white crystalline, odorless solid that absorbs moisture from the air. When dissolved in water or neutralized with acid, it liberates substantial heat, which may be sufficient to ignite combustible materials.

Routes of Exposure Inhalation
Inhalation of sodium hydroxide dust, mist, or aerosol may cause irritation of the mucous membranes of the nose, throat, and respiratory tract. Sodium hydroxide is odorless; thus, odor provides no warning of hazardous concentrations. Mucous membrane irritation occurs at the OSHA PEL (2 mg/m3) and is generally an adequate warning property for acute exposure to sodium hydroxide. However, workers exposed to prolonged or recurrent mists or aerosols of sodium hydroxide can become somewhat tolerant of the irritant effects. Sodium hydroxide of sufficient strength can hydrolyze proteins in tissues and can kill cells in tissues.

Children exposed to the same levels of sodium hydroxide in air as adults may receive a larger dose because they have greater lung surface area:body weight ratios and increased minute volumes:weight ratios. In addition, they exposed to higher levels than adults in same location. Because of their short stature and higher levels of sodium hydroxide in air found nearer to ground.

Skin/Eye Contact
Children are more vulnerable to toxicants affecting the skin because of their relatively larger surface area: body weight ratio.
Exposure to sodium hydroxide solid or solution can cause skin and eye irritation. Direct contact with the solid or with concentrated solutions causes thermal and chemical burns leading to deep-tissue injuries. Very strong solutions of sodium hydroxide can hydrolyze proteins in the eyes, leading to severe burns and eye damage or, in extreme cases, blindness.

NaOH physical properties and usages:

Sodium Hydroxide Uses
It`s used as raw materials in the manufactures companies such as paper, aluminum, commercial drain, cleaners, soap and detergents.

Cleaning & Disinfectant Products:
Caustic soda is used to manufacture soaps and detergents. Also in home applications. Chlorine bleach is produced by combining chlorine and sodium hydroxide. Drain cleaners that contain sodium hydroxide convert fats and grease that can clog pipes into soap, which dissolves in water.

Pharmaceuticals & Medicine
It uses to help manufacture a variety of medicines and pharmaceutical products, from common pain relievers like aspirin, to anticoagulants that can help to prevent blood clots, to cholesterol-reducing medications.

Energy
In the energy sector, NaOH uses in fuel cell production. Fuel cells work like batteries to cleanly and efficiently produce electricity for a range of applications, including transportation; materials handling; and stationary, portable and emergency back.

Caustic Soda Flakes

What is Caustic Soda Flakes?
Probably Caustic Soda Flakes is the most popular al­ka­li in the world. For industrialist needs, around 55.5 million tons of it is manufactured. Sodium Hydroxide is classified in the group of strong chemical bases, because it`s com­plete­ly dissociates (dissolves) in water.

All about NaOH (Caustic Soda Flakes)
Sodium Hydroxide (NaOH) is solid flakes in white color that also known as caustic soda. NaOH is an inorganic compound. It is an ionic compound consisting of sodium. Furthermore it is a highly caustic base and alkali,that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. Therefore sodium hydroxide uses in many industries like chemical manufacturing, petroleum refining, cleaning compounds, drain cleaners.

Caustic Soda Flakes, specially appears as White or nearly white pellets, flakes, sticks, fused masses. In addition,Lye is clear or slightly turbid, colorless or slightly colored, strongly caustic and hygroscopic and when exposed to the air they absorb carbon dioxide (CO2), forming sodium carbonate.

Sodium Hydroxide is formed from sodium sulfate by a three step operation comprising converting the sodium sulfate to sodium sulfide, converting the sodium sulfide to sodium bicarbonate, and converting the sodium bicarbonate to sodium hydroxide. Operations are effected in conjunction with a bleached craft pulp mill operation, so as to utilize by-product sodium sulfate from chlorine dioxide generation to produce useful NaOH as sulfur without co-producing chlorine.

Caustic Soda Flake Uses
All household specially Agents, shampoo and soap have a certain amount of caustic soda added to them.
Paper, polyester fiber and cardboard factories.
In aluminum manufactures, also is added for pickling metal.
NaOH food grade is an additive. It uses to make crunchy crusts.
As washing agent lye can breaks down fats in food factory.Also it would used in peeling fruit.
Caustic soda also uses for cleaning laboratuvar pipes so sodium hydroxide uses as solvent
Bio-diesel fuel (an ecology discovery).
NaOH uses for testing re-actions at chemical plants
It also has an interesting method of application in medicine – for burning off skin growths; then a scab appears.
Precautionary Statements
Chemical retractions with caustic soda: First help is urgent if the solution/powder touches skin, mucous membranes or eyes. If it gets in your eyes, immediately rinse them with a large amount of water. Then show the damaged eye to the doctor, because irreversible changes can be by hard burns.

Because The solution has a strong alkaline re­ac­tion, so litmus paper turns to dark blue (with phe­nolph­thalein the presence of the OH group gives a raspberry color, with methyl orange it may seem yellow). because of activity the substance, re­acts with almost any chemical compound

Acids (it forms salts and water.)
Am­pho­ter­ic hydroxides.
Am­pho­ter­ic oxides (this re-action forms water and complex compound)
Salts (caustic soda can provide the most of all effects of precipitation of metals, it forms a sediment in the form of metal hydroxides)
Non-metal and halogens.
Metals (apart from iron and copper, as they have a low elec­tro­chem­i­cal potential).
Ethers and alkyl halides a hydrolysis re-­ac­tion arises.
Poly­atom­ic alcohols (reagents may transform into alkox­ides)
Fats (using for irreversible reaction of saponi­fi­ca­tion,in this process fats turn into soap and glycerin.)

NaOH Uses and Hazards
Caustic soda flake is mostly uses as industrial raw material. Chemical industry uses around 56% of Sodium Hydroxide, while the paper industry uses 25% of the same total.
This Caustic Soda Flake (NaOH) is often as liquid, for handling easier also cheaper price. Sodium Hydroxide solid also used for production of sodium salts and detergents, for organic synthesis, and for pH regulation.
It uses in Bayer process of aluminum manufacture. Also, crude oil with poor quality can be treated with caustic soda flake to remove sulfurous impurities in one process known as caustic washing. As above, reaction between Caustic Soda Flake (NaOH) with weak acids like mercaptans and hydrogen sulfide to give removable non-volatile sodium salts. Then, it forms waste such as toxic, which is difficult to deal with.

Produced NaOH by membrane cell process, typically brought up as Membrane Grade.

Caustic Soda Liquid
Caustic Soda Liquid also known as lye is a metal hydroxide traditionally obtained by leaching ashes. This formula containing largely Potassium Carbonate or “potash”. in addition it includes a strong alkali which is highly soluble in water producing caustic basic solutions. “Lye” is almost an alternative name of Sodium Hydroxide (NaOH). Also this name historically uses for potassium hydroxide (KOH). Though the term “lye” refers to any member of a broad range of metal hydroxides.

Today, lye is commercially manufactured using a membrane cell chloralkali process. It is supplied in various forms such as Flakes, pellets, microbeads, coarse powder and a solution.

Caustic Soda Liquid Types
Sodium Hydroxide solution is a colorless liquid and it`s density is more than water. Contact maybe severely irritate skin, eyes and mucous membranes. Toxic by ingestion, Could be causes corrosive to metals and tissue. Also best place to keep is dry stock with temperature between 15 – 55 oC. Warm weather ( 55 oC) maybe damage the package. In -15 oC liquid will be freeze. NaOH mades by changes the electrolytic chlor alkali process. In this process also Chlorine gas gets, as a result.
