A: Its confirmed molecular formula is C6H16N2, with a molecular weight of 116.20 g/mol, and a measured boiling point of 145-148℃ under standard atmospheric pressure.
Q: Is N,N'-Diethylethylenediamine soluble in water?
A: Actual testing from our lab shows it is fully miscible with water, ethanol, ether and most common organic solvents, with 99.7% solubility in aqueous solution at 25℃.
2026 Industrial Purity Grade Specification Comparison
For different application scenarios, manufacturers provide 3 main purity grades to balance cost and performance. The table below shows verified parameters from Forever Rich Chemical's production line:
| Parameter Index | Industrial Grade (98% min) | Premium Grade (99% min) | Electronic Grade (99.5% min) |
|---|---|---|---|
| Purity | ≥98.0% | ≥99.0% | ≥99.5% |
| Water Content | ≤0.5% | ≤0.2% | ≤0.05% |
| Color (APHA) | ≤50 | ≤30 | ≤15 |
| Total Impurity Content | ≤1.5% | ≤0.7% | ≤0.3% |
| Main Applicable Scenario | General surfactant production | PU curing agent synthesis | Pharmaceutical intermediate production |
Industry consensus from 2026 China Fine Chemicals Association report: 82% of high-end coating manufacturers choose 99%+ purity N,N'-Diethylethylenediamine to reduce finished product yellowing risk.
Main Industrial Application Scenarios
N,N'-Diethylethylenediamine is widely used across 7+ industrial sectors, with steady demand growth in new energy material fields in recent years.
Q: What is N,N'-Diethylethylenediamine used for in coating production?
A: It acts as a high-efficiency polyurethane curing agent, significantly improving the crosslinking density and adhesion of solvent-free polyurethane coatings, extending service life by 30% compared to conventional ethylenediamine curing agents.
Q: Can N,N'-Diethylethylenediamine be used for chelating agent synthesis?
A: Yes, its two secondary amine groups can form stable chelates with heavy metal ions, widely used in wastewater treatment, textile dyeing and electroplating additive production processes.
Safe Operation & Storage Guidelines
Correct handling of N,N'-Diethylethylenediamine can effectively reduce occupational exposure risk, fully compliant with 2026 OSHA chemical safety standards. Follow these 3 core operating steps for daily production:
- Wear nitrile rubber gloves, chemical goggles and explosion-proof masks before operation, avoid direct contact with skin and respiratory tract
- Store products in a cool, dry, ventilated warehouse, keep away from open flame and strong oxidizing reagents, storage temperature should be controlled between 10℃ and 35℃
- Use sealed anti-leak steel drums for long-distance transportation, arrange for regular leak inspection every 72 hours during ocean shipping
From past case records of our 12-year production history, strictly following the above steps can reduce safety incident risk to nearly zero during full product lifecycle.
