What is Liquid Sodium Hydroxide 32%, 45%, 50%?
Liquid sodium hydroxide 32% (NaOH) refers to sodium hydroxide with a concentration of 32% - 50%. This is one of the commonly used industrial chemicals today. In addition to being called liquid sodium hydroxide, it is also known by several other names such as caustic soda, lye, and sodium hydroxide.
This chemical readily dissolves in water, alcohol, and glycerin. However, it does not dissolve in ether and other non-polar solvents.
Characteristics of Liquid Sodium Hydroxide 32%, 45%, 50%
Liquid sodium hydroxide 32% - 50% is not only used in industry but also in laboratories. Like conventional sodium hydroxide, this type of lye possesses certain physical and chemical properties:
Physical properties
- Exists in liquid form, white in color, and has a strong hygroscopic ability.
- Odorless, highly soluble in alcohol or cold water.
- Solubility at room temperature (20°C): 111 g/100 ml.
- Boiling point of liquid sodium hydroxide: 1390°C.
- Melting point of liquid sodium hydroxide: 318°C.
- Density of liquid sodium hydroxide 32% - 50%: 2.13 (density of water = 1).
- pH concentration = 3.
- Molecular weight of liquid sodium hydroxide: 39.9971 g/mol.
Chemical properties
- Reacts with acids/acid oxides to produce salts and water:
NaOH + HCl → NaCl + H2O
- Reacts with carbon dioxide to produce carbonate salts:
2NaOH + CO2 → Na2CO3 + H2O
- Reacts with strong metals to produce new metal and base products:
NaOH + K → KOH + Na
- Reacts with salts to produce new salts and bases:
CuCl2 + 2NaOH → Cu(OH)2 + 2NaCl
Key Applications of Liquid Sodium Hydroxide 32%, 45%, 50% in Practice
Liquid caustic soda (NaOH) is a highly versatile and widely used chemical in various concentrations, including 32%, 45%, and 50%. Each concentration has its specific applications, making sodium hydroxide a critical component in numerous industries. Here are the key applications of NaOH at these concentrations:
Water treatment
Liquid sodium hydroxide 32% - 50% is used to treat acidic wastewater to increase the water’s pH. Sodium hydroxide will generate hydroxides to remove heavy metals, and neutralize and remove deposits in water pipes while increasing the pH in Cyanua treatment reactions, Nito Stripping towers, etc. Additionally, sodium hydroxide aids in resin regeneration.
Chemical Manufacturing
Sodium hydroxide is a fundamental ingredient in the production of a variety of chemicals. It is used in the manufacture of sodium salts, detergents, and other sodium compounds. It also plays a role in the production of dyes, pharmaceuticals, and synthetic fabrics.
Paper and Pulp Industry
NaOH is extensively used in the paper and pulp industry for the pulping and bleaching processes. In Kraft paper production, an alkali mixture containing NaOH and Na2S is used to dissolve lignin and semi-cellulose present in straw, bamboo, wood chips, etc. The purpose of this is to release fiber cellulose.
Food Industry
NaOH 32% is used in food processing, especially for peeling fruits and vegetables, processing chocolate and cocoa, and in the production of caramel color. It is also used to produce soda and to neutralize acids in food products.
NaOH 45%, 50%: Higher concentrations are generally used for cleaning and sanitizing equipment in food and beverage processing facilities.
Petroleum industry
Liquid lye is used to adjust the pH of drilling fluid to remove sulfur, a component found in crude oil.
Textile Industry
It is used in the textile industry for processes such as scouring, which removes impurities from fibers, and mercerizing, which improves the strength, dye uptake, and luster of cotton fabrics.
Soap and Detergent Production
Sodium hydroxide is a key ingredient in the production of soaps and detergents. It saponified fats and oils to produce soap, and it is used in the manufacture of detergents for its ability to break down grease and fats.
Pharmaceuticals
NaOH is utilized in the pharmaceutical industry for the synthesis of various drugs and as a pH regulator during the production process.
Guidelines for Proper Storage and Incident Handling of Liquid Sodium Hydroxide 32% - 50%
Similar to other chemicals, the storage and handling of incidents related to liquid sodium hydroxide NaOH need to adhere to specific regulations:
Storage
Store in cool, dry, and well-ventilated areas, away from direct sunlight.
The storage area should be kept away from acids, oxidizing agents, reducing agents, and metals such as aluminum, zinc, magnesium, etc.
Store liquid NaOH in specialized plastic or light steel drums and tightly close the lids.
Incident Handling
When chemicals come into contact with the eyes, immediately remove contact lenses (if worn), then rinse with clean water for at least 15 minutes. Subsequently, seek medical attention at the nearest healthcare facility for examination and treatment.
If liquid lye splashes onto the skin, handle it as follows:
- Remove clothing and shoes carefully to avoid further exposure.
- Rinse the affected skin area with clean water for at least 15 minutes. If heavily splashed with lye, use soap to wash, then apply antibacterial cream.
- Apply a soft bandage to cover the burned skin area.
- Transfer promptly to the nearest healthcare facility for prompt examination and treatment.
- For clothing and shoes, wash thoroughly before reuse.
Inhalation of chemical fumes:
- Move the victim to a well-ventilated, safe area.
- Loosen or remove clothing.
- If the victim stops breathing, adm inister artificial respiration immediately.
- Transfer the victim to the nearest healthcare facility for further treatment.
To ensure safety, workers should wear appropriate protective clothing when working with chemicals, including gloves, masks, safety glasses, and safety shoes. In poorly ventilated work areas, workers should wear clothing with additional respiratory support.
