What are the uses of sodium hydroxide technical grade?

Sodium hydroxide technical grade, a toxic substance and hazardous chemical. This may be used as a strong base in chemical solutions, including soap solutions and cleaning agents, to remove grease or oil from surfaces or dissolve some types of materials. It is also used as an electrolyte for sodium sulfate in viscous liquids, as well as in the production of hydrogen sulfuric acid and hydrochloric acid.

Uses of sodium hydroxide technical grade

1. To produce sodium hydroxide liquid, it is used as a catalyst in the production of synthetic ammonia and butadiene.

2. It is also used in the regulation of hydrogen sulfide in oil drilling.

3. It can be used to remove scale from pipes and tubes by pouring 40% or 50% solutions on them, which serves to remove small amounts of particulate matter and other foreign substance from water in industrial applications, cleaning or water purification systems, small municipal water treatment plants, wastewater treatment facilities and swimming pools with calcium deposits or high pH.

4. Used in detergents for washing cars or any other surfaces where you require high alkaline solutions.

5. Also used as surfactant in soaps, detergents and masks, suitable for washing clothes and dishwashing liquid.

6. Used as a disinfectant, especially in water treatment plants to remove organic matter that are not suitable for other sources of biological oxygen demand, but is not soluble in water.

7. Used in household cleaners where you need to dissolve grease or oil stains on glass or aluminum surfaces after cleaning made with alkali levels than the paper can absorb (both ammonia and sodium hydroxide), these products clean better than the common detergent soap.

8. Because of its high pH, sodium hydroxide is also used in food for cooking and preparation. In many cases, sodium hydroxide applied in local restaurants to fries (which are cooked with very hot water) to improve the flavor and consistency of the potatoes.

9. To extract oil from some solids such as grains or nuts, including coffee beans and peanuts, it is used with a mixture of liquid ammonia at low temperatures so that the oil can be separated easily by immiscible ethanol-water gel.

10. It is also used in laboratories to remove the salts of metals and sulfides.

11. Used to produce sodium hydroxide solid, this material is mainly used in pharmaceuticals, food and chemical industries, etc., it will be the sodium hydroxide crystals with the same melting point as the liquid.

12. Sodium hydroxide technical grade can be dissolved in water at high temperatures caused by heat of an explosion, which also results in changes in its properties and appearance (such as color). This process is similar to an oxidation reaction, which can cause changes in other products that could depend on what it produces or what causes it.

Dangerous effects of sodium hydroxide

1. Since sodium hydroxide is a strong base and is corrosive, it can cause skin burns. If the solution touches the skin or eyes, you should rinse it with plenty of water. If the acid enters the eye, it can harm the surface of the eye and cause blindness.

2. Because sodium hydroxide is a strong base, the main danger arises when mixing with acids or acid materials.

3. The reaction between sodium carbonate and chlorine leads to dangerous gases such as chlorine gas and phosgene that causes severe lung damage in humans (such as pneumonia). Other dangerous substances include hydrogen gas, a flammable gas that causes severe burns if it comes into contact with fire or a spark source.

4. When exposed to moisture, sodium hydroxide may result in the release of heat that produces steam, thus increasing the pressure and causing a risk of explosion.

5. If overheated, sodium hydroxide may cause thermal decomposition and form corrosive fumes that can damage lungs.

6. Some solutions containing large amounts of sodium hydroxide are not recommended for you to drink because they are very corrosive and can seriously harm your intestines or esophagus if swallowed. They can also cause irritation if they get on the skin or in your eyes.

7. In the case of accidental contact with sodium hydroxide, chemicals or strong alkali solutions, it is advisable to rinse immediately with plenty of water.

Conclusion

At present, sodium hydroxide technical grade is one of the most important chemicals in chemical industries and it has numerous uses. Although it is a strong base and can cause serious damage to human body if exposed to skin or eyes, we need to be very careful and cautious when using sodium hydroxide.
