What is NaOH (Caustic Soda)? – IMPORTANT ROLE IN INDUSTRY AND LIFE

NaOH (caustic soda)

– IMPORTANT ROLE IN FIELDS

I. Concept : Sodium hydroxide or Sodium Hydroxide (chemical formula NaOH) or commonly known as lye or caustic soda is an inorganic compound of sodium. Sodium hydroxide forms a strong basic solution when dissolved in a solvent such as water. Liquid NaOH solutions are viscous, causing damage to fabric, paper, and skin.

II. Properties of Caustic soda:

White solid in pellet, flake or granule form (NaOH 98%, NaOH 99%)

Or in liquid form concentration NaOH 10%, NaOH 20%, NaOH 32%, NaOH 45% …saturated solution at 50%

Strong hygroscopicity, highly soluble in water and heat release

Caustic soda easily absorbs CO2 from the air, so it is often stored in a tightly closed container. In solution, caustic soda forms a monohydrate at 12,3 - 61,8 degrees Celsius, the melting point is 65,1 degrees Celsius and the density is 1,829 g/cm3.

Sodium hydroxide solution is greasy, can damage fabric, paper and corrode skin.

III. Applications of caustic soda NaOH :

1, In the field of life

NaOH (lye) widely used in life to treat swimming pool water, wastewater, and domestic water with the task of adjusting pH, bringing the pH concentration to the required level, to carry out the next water treatment steps.

In addition, adding caustic soda to water will help some metal hydroxides form a more stable form and easily precipitate or form glue. On the other hand, with some wastewater containing high COD content, the use of xut Increasing the pH concentration will help the water treatment by microbiological method to take place more smoothly. Specifically, when the pH concentration increases to the required level, this is a favorable environment for microorganisms to grow and develop. At that time, the swimming pool water treatment will be most effective.

2, In the pharmaceutical industry: NaOH used to produce drugs containing the radical Sodium (such as aspirin), or as a bleaching agent, disinfectant, etc.

3. In the detergent manufacturing industry:

NaOH and sodium compounds are considered important ingredients in the production of laundry detergents such as country Javen is a fairly effective bleaching agent. In addition, Sodium Hydroxide It also has the effect of hydrolyzing fats in animal fats, so this chemical is also used as dishwashing liquid.

Besides, by mixing this chemical with hot water, then NaOH chemical will create effective cleaning agents for technological equipment, tanks, waste pipes under sinks and drains, drainage pipes. Or when soaking stainless steel, baked glass in caustic chemicals, it also has a very good degreasing effect, people also use them as boiler cleaning chemicals. NaOH also has a positive effect in cleaning the washing machine drum, helping to improve the washing machine after a period of use.

4, In the textile and dyeing industry: Caustic soda is used as a decomposing agent for pectins and waxes in the processing of raw fabrics.

Caustic soda Used in the rayon fiber industry: To decompose lignin – a harmful substance that often accompanies cellulose in wood pulp, caustic soda is used.

5, In the paper industry In this industry caustic soda has the effect of treating and whitening wood, bamboo, rattan, etc. using Sulfate and Soda technology.

6, In the food processing industry: In this industry, the application of NaOH is to remove fatty acids in the refining process of vegetable and animal oils before these materials are used to produce food. In addition, people also use xut This is used to mix bottle cleaning solutions, sterilize equipment in breweries, or to mix alkaline solutions to treat vegetables and fruits before processing or canning.

7, In the oil and gas industry: Caustic soda used to adjust the pH of drilling fluids, such as removing sulfur and acid compounds found in petroleum refining...

8, In the water treatment industry: Caustic soda helps regulate pH and regenerate resins in the ion exchange process. In addition, caustic soda is also used for neutralization and descaling in water supply pipes.

IV :Note when using caustic soda NaOH

• Skin contact may cause skin corrosion, irritation, burns, and absorption through the skin. Symptoms include itching, scaling, redness, and burning.
• In case of contact with skin, remove all clothing and shoes, then rinse with clean water for at least 15 minutes. Cover the burned skin with a soft bandage to prevent the caustic soda from eating away at the skin. In more serious cases, wash with soap, apply anti-bacterial cream, and then go to the nearest medical facility.
• Mutagenic: Breast cells leading to breast cancer. Also damages organs such as the mucous membrane, respiratory system, skin and eyes.
• When caustic soda comes into contact with the eyes it can damage the lens or cause blindness, with symptoms of red eyes, watery eyes and itching.
• Inhaling caustic soda dust or swallowing it will affect the respiratory system, inhaling too much can damage the lungs, cause suffocation, drinking it can damage the intestines, faint or even death. Symptoms of inhaling caustic soda include burning of the lungs, sneezing, coughing...
