Sulphonic acid 96%

Sulphonic Acid

Sulphonic acid is a general term for a family of organic compounds that contain the functional group −SO3H-SO_3H−SO3​H. It is a highly versatile and widely used industrial chemical, especially in the detergent and cleaning product industries.

Key Properties:

Chemical Formula:

• R-SO3​H, where RRR is an organic alkyl or aryl group.

Physical Appearance:

• A viscous, clear to pale yellow liquid.

Solubility:

• Highly soluble in water and polar solvents.

pH:

• Strongly acidic in nature.

Odor:

• Slightly pungent or chemical-like odor.

Density:

• Approximately 1.06–1.08 g/cm³ (varies depending on grade and concentration).

Applications:

1. Detergent Manufacturing:

• Surfactant Production: Used to produce linear alkylbenzene sulfonate (LABSA), a key surfactant in household and industrial detergents.
• Enhances cleaning power by emulsifying oils and greases.

2. Textile Industry:

• Acts as a wetting agent and dye dispersant.

3. Leather Industry:

• Used in tanning and leather processing for better penetration of chemicals.

4. Cleaning Products:

• Common ingredient in floor cleaners, tile cleaners, and industrial degreasers.

5. Chemical Intermediary:

• Used to synthesize other chemicals like sulfonates and sulfonamides.

6. Oil and Gas:

• Functions as a corrosion inhibitor and drilling fluid additive.

Advantages:

Strong Cleaning Action:

• Removes grease, oil, and dirt effectively.

Emulsification:

• Stabilizes oil-in-water emulsions, enhancing cleaning efficacy.

Cost-Effective:

• Readily available and economical for large-scale production.

Biodegradability:

• Many sulfonate derivatives, like LABSA, are biodegradable, making them more environmentally friendly.

Handling and Safety:

1. Precautions:

• Skin Contact: Strongly acidic; wear gloves and protective clothing.
• Eye Contact: Use goggles to avoid irritation or burns.
• Inhalation: Work in well-ventilated areas or wear a mask to prevent respiratory irritation.

2. Storage:

• Store in tightly sealed containers made of acid-resistant materials (e.g., polyethylene or stainless steel).
• Keep in a cool, dry place away from incompatible materials like alkalis.

3. Emergency Measures:

• Skin Contact: Wash thoroughly with water.
• Eye Contact: Flush eyes with water for at least 15 minutes and seek medical attention.
• Inhalation: Move to fresh air immediately.

Chemical Reactions:

R-SO3​H+NaOH→R-SO3​Na+H2​O

Neutralization:
Reacts with bases (e.g., sodium hydroxide) to form sulfonate salts, which are common detergents:

Emulsification:
Sulphonic acids can break down oils into smaller droplets for easier cleaning.

Grades of Sulphonic Acid:

1. LABSA (Linear Alkylbenzene Sulfonic Acid):
   • Most common variant used in detergents.
2. Secondary Alkane Sulphonic Acid (SASA):
   • Used in niche applications for specific cleaning and emulsifying needs.

Packaging:

• Available in 200 kg drums, bulk containers, or smaller quantities for specialized use.

Environmental Considerations:

• Biodegradability: LABSA, a derivative of sulphonic acid, is biodegradable but can contribute to water pollution if not treated before disposal.
• Proper wastewater treatment is essential to minimize environmental impact.
