Product Details

CasNo： 75-04-7

MF： C2H7N

Appearance： liquid

Delivery Time： 15 days

Packing： 200kg/drum

Purity： 70%

1. Basic Information

• Chinese Name: 一乙胺 (Ethylamine)
• English Name: Ethylamine (70% Aqueous Solution)
• CAS Number: 75-04-7
• Molecular Formula: C₂H₇N
• Molecular Weight: 45.108
• Appearance: Colorless transparent liquid, highly volatile, with an ammonia-like odor.

2. Physicochemical Properties

• Density: 0.810–0.812 g/mL (at 20℃, measured for the 70% aqueous solution).
• Refractive Index: 1.383–1.384 (at 20℃, reflects the purity and uniformity of the solution).
• Solubility: Miscible with water, ethanol, ether, and other polar/non-polar solvents; the aqueous solution can be diluted arbitrarily without phase separation.
• Stability: Chemically reactive—easily oxidized by oxidizing agents (e.g., hydrogen peroxide, chlorine) and reacts violently with strong acids (e.g., sulfuric acid, hydrochloric acid) to form salts. It is not stable in high-temperature environments (decomposition may occur above 100℃).
• Volatility: Highly volatile; the vapor is heavier than air and can spread along the ground to ignition sources, posing a fire hazard.

3. Quality Indicators

Typical industrial-grade 70% Ethylamine adheres to the following quality standards (for reference only; specific indicators may vary by manufacturer):

4. Applications

• Pharmaceutical Industry: Serves as a key intermediate for fungicides (e.g., cymoxanil, ethirimol) and certain antibiotics. It is also used in the synthesis of local anesthetics and antihistamine drugs.
• Pesticide Industry: Critical raw material for producing triazine herbicides (e.g., atrazine, simazine) and organophosphorus insecticides (e.g., propetamphos). It enhances the efficacy and stability of pesticide formulations.
• Chemical Synthesis: Used in manufacturing dyes (e.g., azo dyes), surfactants (e.g., cationic amine surfactants), and ion exchange resins. It also acts as a neutralizer or catalyst in organic synthesis reactions.
• Other Fields: Applied as a metallurgical flotation agent (aids in separating minerals from ores) and a rubber vulcanization accelerator (improves the mechanical properties of rubber products).

5. Packaging and Storage

• Packaging:
  • Industrial bulk packaging: Typically uses 150 kg iron drums (inner wall coated with anti-corrosion material to prevent metal reaction with ethylamine) or 160 kg steel drums.
  • Small-volume packaging: Available in 0.36 kg fiberboard boxes (inner liner: HDPE plastic bags) for laboratory testing or small-batch trials.
  • All packages must be hermetically sealed to prevent volatilization and moisture absorption.
• Storage Conditions:
  • Store in a cool, well-ventilated warehouse (temperature ≤30℃) away from ignition sources (e.g., open flames, heaters) and heat sources.
  • Keep away from incompatible substances: oxidizing agents, strong acids, and halogens (e.g., chlorine, bromine).
  • Use explosion-proof electrical equipment in the storage area; avoid static electricity (ground containers during handling).
  • Shelf life: Typically 12 months under proper storage conditions (sealed, cool, dry).

6. Safety Information

• Hazard Class: Flammable liquid (UN number: 1104); vapor is toxic and irritating to the eyes, skin, and respiratory tract.
• Protective Measures: Wear chemical-resistant gloves, goggles, and a gas mask when handling. In case of skin/eye contact, rinse immediately with plenty of water for 15+ minutes.
• Emergency Handling: If a leak occurs, evacuate the area, ventilate thoroughly, and use absorbent materials (e.g., sand, vermiculite) to contain the spill (do not flush with water directly, as it may spread the liquid).
