n- PROPANOL

n-Propanol, also known as 1-propanol, is a colorless, flammable alcohol with a characteristic odor. It is widely used as a solvent, intermediate in chemical synthesis, and as a cleaning agent in various industrial, laboratory, and commercial applications. n-Propanol has a wide range of uses due to its ability to dissolve both polar and non-polar substances. It is commonly employed in the manufacture of pharmaceuticals, personal care products, and in chemical reactions.

     n-Propanol is used as a fuel or additive in gasoline to improve combustion properties and reduce engine knocking.

Safety and Handling

• Hazards:
  • Flammable: n-Propanol is highly flammable and can pose a fire risk.
  • Health Risks: Prolonged exposure or ingestion may lead to respiratory or gastrointestinal issues.
  • Skin and Eye Irritation: Can cause irritation or burns upon contact with skin and eyes.
• Precautions:
  • Personal Protective Equipment (PPE): Wear appropriate protective gloves, goggles, and flame-resistant clothing when handling n-Propanol.
  • Ventilation: Ensure proper ventilation when using n-Propanol in closed spaces to avoid inhaling vapors.
  • Fire Safety: Keep away from open flames, sparks, and other ignition sources. Store in a cool, dry, well-ventilated area away from heat or flame.
• First Aid:
  • Eye Contact: Flush eyes immediately with water for 15 minutes and seek medical attention if irritation persists.
  • Skin Contact: Wash skin thoroughly with soap and water. If irritation or redness occurs, consult a doctor.
  • Inhalation: Move to fresh air immediately. If symptoms such as dizziness or difficulty breathing occur, seek medical attention.
  • Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by a medical professional. Seek immediate medical help.
