Basic chemicals definition
Common basic chemicals
Basic chemicals are divided into two main groups:

Inorganic chemicals:

Sulfuric acidSulfuric acid“King of chemicals,” used in the production of fertilizers, detergents, and water treatment.
Sodium hydroxide (NaOH chemicalCaustic soda, widely used in paper production, soap, and wastewater treatment.
Aluminum sulfate (Chemical Al2(SO4)3): Effective coagulant in water treatment and the textile industry.
Ammonia (NH₃): A raw material for the production of fertilizers and many other nitrogen chemicals.

Organic chemicals:

Ethylene (C₂H₄) and propylene (C₃H₆): The main monomers for the production of polyethylene and polypropylene plastics.
Methanol (CH₃OH): An important solvent and organic synthesis raw material.
Benzene (C₆H₆): Used in the production of plastics and synthetic fibers.

Commonly Supplied Basic Chemicals

CharacteristicsSulfuric acid is an indispensable chemical in many industries, serving as a strong oxidizing agent and catalyst.
Applications:

Production of fertilizers and detergents.
Wastewater treatment and oil refining.

Notes when purchasingPrioritize the ISO certified chemical supplier to ensure product quality.

Aluminum Sulfate (Al₂(SO₄)₃)

CharacteristicsAluminum sulfate is often sold as a white powder or crystal, easily soluble in water.
Applications:

Wastewater treatment, flocculating impurities.
Used in the dyeing and paper manufacturing industries.

3. Poly Aluminium Chloride (PAC)

Applications:

Treatment of raw water, industrial wastewater, and domestic wastewater.
Remove bacteria, viruses, and organic matter.

4. Ammonia (NH₃)

Characteristics: It is a strong alkaline gas, usually sold as a compressed gas or solution 25%.
Applications:

Fertilizer production, nitric acid.
Industrial exhaust cooling and treatment.

Sodium Hydroxide (NaOH)

CharacteristicsKnown as caustic soda, NaOH is a basic chemical that is widespread nationwide supply.
Applications:

Production of soap, paper, and wastewater treatment.
Use in food processing.

Applications of Basic Chemicals in Industry

Textiles:

Sodium hydroxide is used in the mercerization process, enhancing the luster and durability of cotton fabric.
Sulfuric acid and hydrogen peroxide assist in dyeing and bleaching processes.

Paper industry:

Sodium hydroxide dissolves lignin in wood, while chlorine or aluminum sulfate bleaches and improves product strength.

2. Water Treatment
Water treatment is one of the most important application areas for basic chemicals, especially in the context of increasing environmental pollution. Solutions Water treatment chemicals not only helps improve wastewater quality before discharge into the environment but also ensures that the water supply meets safety standards for living and production. Here are methods for effective chemical use in wastewater and water treatment.

wastewater treatment:

Alum and PAC help to coagulate, remove dirt, and insoluble impurities.
Sulfuric acid and NaOH are used to adjust pH, optimizing treatment efficiency.

Treated water supply:

Chlorine and sodium hypochlorite (NaClO) effectively disinfect, ensuring safe clean water.

3. Auxiliary Chemical Production

Oil and gas industry:

HCl and NaOH are used in the production of drilling additives, protecting equipment from corrosion, and optimizing drilling performance.

Plastics industry:

Styrene and ethylene are the main raw materials in polymer production, creating polyethylene and polypropylene plastics.

Notes on the Use and Storage of Chemicals

Occupational Safety:

Equip yourself with gloves, safety glasses, and a gas mask.
Follow the instructions in the MSDS documentation.

Storage:

Store chemicals in a dry place, away from direct sunlight and high temperatures.
Ensure containers are sealed to prevent chemical leaks or evaporation.
Do not store H₂SO₄ and NaOH together—dangerous exothermic reaction.

Troubleshoot:

Equip a spill containment system and auxiliary tools such as secondary containment bins, clay, or sand.
Equip emergency eyewash stations according to TCVN 5507:2002.

Frequently Asked Questions About Basic Chemicals

What are basic chemicals and how do they differ from specialty chemicals?
Basic/commodity chemicals are chemical compounds produced on a large industrial scale, with simple formulas such as H₂SO₄, NaOH, HCl, NH₃. They differ from specialty chemicals in that they are used as raw materials for many industries, are produced in large quantities, have lower costs, and do not require special refinement for each end application. Specialty chemicals are synthesized from basic chemicals, have higher purity, and more complex formulas.

PAC and alum (Al₂(SO₄)₃) are different in the following ways:
PAC (Poly aluminum chloride) has stronger flocculation capabilities than aluminum sulfate due to its longer aluminum polymer chains; it is effective over a wide pH range (5–9), forming larger flocs that settle more quickly. Aluminum sulfate is suitable for treating water with low turbidity and on a limited budget. For industrial wastewater with high suspended solids (SS) content or dye contamination, PAC typically provides better treatment performance than 15–25%. Loc Thien supplies both types and offers free consultation via our hotline. 0979 891 929.

What documents are needed to purchase basic chemicals?
According to Decree 113/2017/ND-CP, some basic chemicals such as concentrated H₂SO₄, HCl, and NH₃ are on the list of chemicals subject to conditional business. Purchasing businesses need to provide: Business license, chemical reception slip, and a commitment to proper use. Loc Thien provides full documentation: COA (Certificate of Analysis), MSDS (Safety Data Sheet), and VAT invoices in compliance with regulations.

How should sulfuric acid (H₂SO₄) and sodium hydroxide (NaOH) be stored to ensure safety?
H₂SO₄ must be stored in HDPE plastic tanks/cans or stainless steel, avoiding contact with ferrous metals and water (strong exothermic reaction). NaOH is highly hygroscopic, must be stored sealed in PE bags or closed containers, away from damp areas and aluminum materials. Both must not be stored together. The chemical storage area must have a ventilation system, temperature below 35°C, acid/alkali-resistant flooring, and be equipped with an emergency eyewash station according to TCVN 5507:2002.
