HEAVY ALKYLBENZENE (HAB)

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

CHEMICAL DESCRIPTION:

Heavy Alkylbenzene (HAB) is a high-purity aromatic hydrocarbon compound. It is the primary raw material used in the production of Linear Alkylbenzene (LAB), which is a key intermediate in the manufacture of biodegradable detergents and surfactants. Its high purity and low color value ensure reliable performance in industrial applications. HAB is characterized by its high flash point, low sulfur content, and excellent thermal stability.

11. SUMMARY AND CRITICAL WARNINGS

SUMMARY:

Heavy Alkylbenzene (HAB, CAS 68648-87-3) is a high-purity aromatic hydrocarbon used as the primary raw material in Linear Alkylbenzene (LAB) production for the detergent and surfactant industry. It is characterized by high purity (≥ 94.5%), low color value (L–1.0), high flash point (191°C), and excellent thermal stability.

Its most important application is in the production of Linear Alkylbenzene (LAB) for biodegradable detergents and surfactants. It is also used in industrial cleaning products, lubricant additives, and specialty chemical synthesis.

Key Advantages:

• High purity ensures efficient LAB production

• Low color value results in cleaner final products

• High flash point provides safe storage and transportation

• Environmentally friendly (low sulfur content)

• Excellent thermal stability

Key Properties:

CRITICAL WARNINGS:

1. High Purity Requirement: HAB content ≥ 94.5% is critical for efficient LAB production. Lower purity can reduce catalyst life and product quality.

2. Moisture Sensitivity: Water content must be < 200 ppm. Moisture can cause hydrolysis and affect downstream processing.

3. Storage Temperature: Store in cool, dry conditions. Avoid direct sunlight and extreme temperatures.

4. Static Discharge: Although HAB has a high flash point, proper grounding is required during transfer to prevent static discharge.

5. Contamination: Avoid contamination with other hydrocarbons or impurities that can affect product quality.

6. Quality Control: Regular testing for HAB content, viscosity, density, color, and water content is recommended for batch-to-batch consistency.
