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

In wastewater 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, 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.

Manufacture of detergent chemicals 

It is used in the production of bleaches, disinfectants, detergents, soaps, etc.

Production of certain pharmaceuticals 

Used to manufacture pain relievers, fever reducers like Aspirin, cholesterol reducers, etc.

Used in the paper manufacturing industry

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.

Artificial fiber production industry

Liquid lye is used to break down lignin, a harmful substance often associated with cellulose in wood pulp.

Food industry

Liquid lye is used to remove fatty acids from animal and vegetable oils during refining. Additionally, it is used to prepare solutions for cleaning bottles, fruits, and vegetables before processing or packaging, or for cleaning machines and equipment in breweries.

Petroleum industry 

Liquid lye is used to adjust the pH of drilling fluid to remove sulfur, a component found in crude oil.

Textile dyeing industry 

In the processing of raw fabric, NaOH is used to break down pectins, waxes to increase fabric shine, while helping the fabric absorb dye faster.

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 lye 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 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, administer 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.
