1. Basic Information

• Chinese Name: 一正丙胺 (n-Propylamine)
• English Name: n-Propylamine (abbreviated as 1-Propylamine)
• CAS Number: 107-10-8
• Molecular Formula: C₃H₉N
• Molecular Weight: 59.11
• Appearance: Colorless hygroscopic liquid with an ammonia-like odor.

2. Physicochemical Properties

• Melting Point: -83℃ (low freezing point, remains liquid in most industrial and ambient environments).
• Boiling Point: 48℃ (high volatility; evaporates rapidly at room temperature, leading to significant vapor accumulation).
• Relative Density: 0.719 g/mL (at 25℃; lighter than water, so spilled liquid floats on water surfaces).
• Flash Point: -37℃ (extremely flammable; classified as a "flammable liquid." Its vapor can form explosive mixtures with air, and even static electricity or small sparks may ignite it).
• Vapor Density: 2 (vs. air; heavier than air), so vapors tend to settle in low-lying areas (e.g., pits, basement corners), increasing inhalation and fire risks.
• Vapor Pressure: 32.9 kPa (at 20℃; high vapor pressure accelerates volatilization, requiring strict sealed storage).
• Solubility: Miscible with water (hygroscopic, easily absorbs moisture from the air); also miscible with ethanol, ether, and soluble in acetone, benzene, and chloroform.
• Stability: Chemically active—reacts readily with acids to form salts, with carboxylic acids/anhydrides to form amides, and oxidizes in air to produce amine oxides. It is incompatible with strong oxidizers (e.g., hydrogen peroxide) and acids (e.g., sulfuric acid), and may undergo violent reactions if mixed.

3. Quality Indicators

Industrial-grade n-Propylamine adheres to strict purity standards, with typical specifications for premium-grade products as follows:

4. Applications

• Organic Synthesis Raw Material:
  • Synthesizes key intermediates such as propyl isocyanate, chloropropylamine, and propyl carbamate (the latter is a widely used textile finishing agent for improving fabric softness and wrinkle resistance).
  • Serves as a building block for preparing nitrogen-containing organic compounds (e.g., amines, amides) in fine chemical production.
• Pharmaceutical Industry:
  Acts as an intermediate in drug synthesis, participating in the production of certain antibiotics, antihistamines, and cardiovascular drugs by providing propylamine functional groups.
• Other Fields:
  • Coatings & Additives: Used in formulating coatings to enhance adhesion and chemical resistance; added to petroleum products as an anti-corrosion additive.
  • Preservatives: Applied in industrial water treatment and metal processing as a preservative to inhibit microbial growth and metal oxidation.
  • Laboratory Reagent: Utilized as an organic synthesis reagent in academic research and industrial R&D.

5. Packaging, Transportation, and Storage

• Packaging:
  • Industrial bulk packaging: Typically 200 kg iron drums (inner wall coated with anti-corrosion resin to prevent reaction between the amine and metal). Custom packaging (e.g., 20L HDPE plastic bottles for small batches) is available upon request.
  • Small-volume laboratory packaging: Sealed glass bottles or plastic containers to prevent hygroscopicity and volatilization.
• Transportation:
  • Classified as a dangerous good (UN number: 1277). Packaged in narrow-mouth steel drums with outer ordinary wooden cases for protection.
  • Equip transport vehicles with fire-fighting equipment (e.g., dry chemical extinguishers) and spill emergency treatment kits.
  • Prohibit mixing with oxidizers, acids, or food chemicals during transport to avoid hazardous reactions or contamination.
• Storage:
  • Store in a cool, well-ventilated warehouse (recommended temperature ≤25℃) away from ignition sources (e.g., heaters, open flames) and heat.
  • Keep containers tightly sealed to prevent volatilization and moisture absorption (due to hygroscopicity). Separate from incompatible substances (e.g., oxidizers, strong acids).

6. Safety Information

• Hazards:
  • The liquid and vapor are irritating—skin/eye contact can cause redness, burning pain, or chemical burns; inhalation of high concentrations may trigger respiratory tract irritation, dizziness, or nausea.
  • Highly flammable: Vapors are explosive when mixed with air, posing severe fire and explosion risks.
• Protective Measures:
  Wear chemical-resistant gloves, splash-proof goggles, and a gas mask (equipped with amine-specific filters) during handling. Ensure the workplace is well-ventilated (use local exhaust ventilation if necessary).
• Emergency Handling:
  • Spill: Evacuate personnel, isolate the area, and cut off ignition sources. Absorb the spill with inert materials (e.g., sand, vermiculite) or neutralize with dilute acid (for small spills).
  • Fire: Use dry chemical extinguishers or carbon dioxide extinguishers; avoid water jets, which may spread the flammable liquid and vapor.
