Product Description

Product Description

Basic Information

• Chemical Name: Naphthenic Acid
• Molecular Formula: Typically expressed as CnH2n−2kO2 (where n is the carbon number, k is the number of rings, usually 1-3)
• Molecular Weight: Varies widely (180-350 g/mol) depending on the hydrocarbon chain and ring structure
• CAS Registry Number: 1338-24-5 (mixture of isomers and homologs)
• Synonyms: Cyclohexanecarboxylic acid derivatives, Petroleum naphthenic acid

Physical and Chemical Properties

• Appearance: Yellow to dark brown viscous liquid; may appear as a solid at low temperatures (melting point depends on composition).
• Melting Point: Usually ranges from -30 to 30 °C (mixture-dependent).
• Boiling Point: Decomposes before boiling under normal pressure; typically distilled under reduced pressure (200-350 °C at 10 mmHg).
• Density: 0.93-1.02 g/cm³ at 25 °C.
• Solubility:
  • Insoluble in water; highly soluble in organic solvents (benzene, ether, petroleum ether).
  • Partially soluble in alcohols and glycols.
• Chemical Characteristics:
  • Weak organic acid with a carboxyl group (−COOH), capable of forming salts (naphthenates) with metals.
  • Thermally stable but decomposes at high temperatures, releasing CO2 and hydrocarbons.
  • Reacts with bases, alcohols (esterification), and metals to form soap-like compounds.

Applications

• Industrial Chemicals:
  • Metalworking Fluids: As rust inhibitors and emulsifiers in cutting oils and lubricants.
  • Drying Agents in Paints: Metal naphthenates (e.g., cobalt, manganese naphthenates) accelerate paint curing.
  • Plasticizers and Stabilizers: For PVC and other polymers to improve flexibility.
• Agriculture and Pharmaceuticals:
  • Pesticide Formulations: As adjuvants to enhance pesticide adhesion and effectiveness.
  • Pharmaceutical Intermediates: In the synthesis of certain drugs and veterinary medicines.
• Corrosion Inhibition:
  • Used in oil pipelines and storage tanks to prevent corrosion by forming a protective film on metal surfaces.
• Other Uses:
  • Mineral Flotation Agents: In ore processing to separate valuable minerals.
  • Surfactants and Detergents: For industrial cleaning applications.
  • Lubricant Additives: To improve the anti-wear properties of lubricating oils.

Safety and Environmental Considerations

• Health Hazards:
  • Skin and Eye Irritation: Direct contact may cause dermatitis or conjunctivitis; use protective gear (gloves, goggles).
  • Toxicity: Inhalation of vapors or ingestion may lead to respiratory irritation, nausea, or organ damage (acute toxicity: LD50 ≈ 200-2000 mg/kg in animals).
• Environmental Impact:
  • Water Pollution: Toxic to aquatic life (EC50 for fish ≈ 1-10 mg/L); persists in water bodies and sediments.
  • Biodegradation: Slowly degraded by microbes, posing a long-term ecological risk.
• Storage and Handling:
  • Store in sealed containers at room temperature, away from strong bases and oxidizing agents.
  • Spills should be cleaned with absorbent materials, and wastewater treated to remove organic acids.
