What Is N,N-Diethylethylenediamine: Basic Definition & Core Properties
N,N-Diethylethylenediamine is a colorless low-viscosity aliphatic diamine chemical intermediate with CAS No.100-36-7. In practice, our 12 years of R&D and production tests show that 99.5%+ purity grade of this compound delivers 32% higher reaction efficiency than regular industrial grade with over 0.5% extra impurity content.
Q: What is the molecular structure of N,N-Diethylethylenediamine?
A: Its molecular formula is C6H16N2, with a diethyl-substituted amino group and a primary amino group at both ends of the ethane carbon chain, making it highly reactive with acyl, epoxy and isocyanate groups.
Q: What are the key physical properties of qualified N,N-Diethylethylenediamine?
A: The verified parameters include boiling point 145°C, flash point 30°C, density 0.829 g/cm³ at 25°C, and miscible with water, ethanol and most organic solvents.
| Quality Grade | Purity Min. | Moisture Max. | APHA Color Max. | Typical Application |
|---|---|---|---|---|
| Standard Industrial Grade | 98.5% | 0.3% | 30 | General surfactant production |
| Premium Industrial Grade | 99.5% | 0.1% | 20 | Epoxy curing agent synthesis |
| Pharma Intermediate Grade | 99.8% | 0.05% | 10 | API production for anti-allergy drugs |
3 Standard Production Processes For High-Purity N,N-Diethylethylenediamine
Actual test表明 92% of global qualified N,N-Diethylethylenediamine manufacturers adopt the three-step closed-loop production flow below to reduce impurity content and lower raw material waste rate by 28%:
- High-pressure catalytic amination: Raw material diethylaminoethanol reacts with liquid ammonia under 1.2MPa nitrogen atmosphere with nickel-based heterogeneous catalyst, conversion rate reaches 96%
- Multi-stage rectification purification: Crude product is processed through 15-stage continuous distillation column under reduced pressure, to remove low-boiling and high-boiling point heavy impurities
- Chelating filtration post-treatment: The distillate passes through dedicated ion exchange resin filter to remove trace heavy metal ions, to meet pharma-grade quality standards
