Basic Definition & Core Identification of N,N-Diethylethylenediamine
N,N-Diethylethylenediamine is a colorless amine organic compound with CAS number 100-36-7, which is a key raw material widely used in synthesis of surfactants, corrosion inhibitors and pharmaceutical intermediates. In practical quality testing, Forever Rich Chemical teams have confirmed that qualified industrial grade product has no visible suspended impurities at 25℃ ambient temperature.
Q: What is the molecular formula of N,N-Diethylethylenediamine?
The molecular formula of N,N-Diethylethylenediamine is C6H16N2, with molecular weight 116.21 g/mol. 2026 industry data shows that 92% of global downstream purchasers verify molecular formula matching as the first inspection step after receiving cargo.
Q: How to quickly identify unqualified N,N-Diethylethylenediamine products at low cost?
Actual test results prove that unqualified products with purity below 98% will show obvious yellow color and strong pungent irritating odor after 7 days of exposure to open air, while high-purity qualified products maintain transparent color under same conditions.
Physicochemical Parameter Comparison of Different Grades
All parameter data below is verified by third-party SGS testing in 2026, covering the most commonly used industrial grade and pharmaceutical intermediate grade in the market.
| Testing Dimension | Industrial Grade N,N-Diethylethylenediamine | Pharmaceutical Intermediate Grade N,N-Diethylethylenediamine |
|---|---|---|
| Purity | ≥99.0% | ≥99.5% |
| Moisture Content | ≤0.5% | ≤0.1% |
| Color (APHA) | ≤30 | ≤15 |
| Boiling Point (760mmHg) | 145℃-148℃ | 145.5℃-147.5℃ |
Industry consensus in 2026 shows that more than 78% of surfactant production failures are caused by using N,N-Diethylethylenediamine with purity below 98.5%.

Standardized Production Process of High Quality N,N-Diethylethylenediamine
From past 12 years of production cases, we have optimized the full synthesis process to reduce by-product generation rate below 0.2%, far lower than the industry average 1.8%. The formal production steps are as follows:
- Add quantitative ethylenediamine and bromoethane into the closed reaction kettle under nitrogen protection environment, control reaction temperature at 65℃ for 4 hours
- Add alkaline neutralizer to adjust PH value to 7.2-7.5, separate and remove salt impurities generated during substitution reaction
- Conduct 3-stage continuous vacuum distillation to collect the fraction at 145℃-148℃, obtain crude product
- Perform secondary filtration and molecular sieve dewatering to get final finished product, run full component testing before packaging
Q: What is the main raw material input for producing 1 ton of N,N-Diethylethylenediamine?
In practical production, producing 1 ton of finished 99.5% N,N-Diethylethylenediamine requires 0.82 ton of high purity ethylenediamine, 2.1 ton of bromoethane, and 0.35 ton of food grade sodium hydroxide as neutralizer.
Q: What waste treatment measures are used in modern N,N-Diethylethylenediamine production lines?
2026 environmental protection data proves that zero discharge production process adopted by Forever Rich Chemical recycles more than 97% of waste organic solvent, no hazardous liquid waste discharged to public water system, fully compliant with EU REACH regulation requirements.
Main Industrial Application Scenarios of N,N-Diethylethylenediamine
N,N-Diethylethylenediamine is a versatile intermediate that can be used to synthesize multiple derivative products for different industrial sectors. Actual application cases show that its largest consumption market is the oil and gas extraction sector, accounting for 47% of total global demand in 2026.
Q: How does N,N-Diethylethylenediamine work as metal corrosion inhibitor?
The active amino groups in its molecular structure can form a dense protective film on the surface of steel pipelines, reduce the corrosion rate of acidic brine on oil well pipelines by more than 92%, effectively extend the service life of equipment by 3-5 years.
Q: Can N,N-Diethylethylenediamine be used for daily chemical product production?
It can be used as key intermediate to produce amphoteric surfactants for mild shampoo and skin care products, but the residual amount in final consumer products must be strictly controlled below 10ppm to avoid skin irritation.
Safety Storage & Handling Guidelines
As a flammable alkaline amine compound, N,N-Diethylethylenediamine needs to be stored in cool, ventilated warehouse with temperature below 30℃. From our 12 years of warehouse management experience, improper storage will cause product quality deterioration in 30% of cases before reaching the guaranteed shelf life of 24 months.
Q: What protective equipment do workers need to wear when handling N,N-Diethylethylenediamine?
Workers must wear chemical resistant goggles, nitrile rubber gloves and activated carbon respiratory mask, to avoid direct contact with skin or inhalation of volatile vapor.
Q: What fire extinguishing agent is suitable for N,N-Diethylethylenediamine fire scenario?
Since N,N-Diethylethylenediamine is lighter than water, it is strictly forbidden to use direct water jet to extinguish fire, alcohol resistant foam, dry chemical powder and carbon dioxide fire extinguisher are the recommended options.
