DGA (diethylene glycol amine)

Introduction of diethylene glycol amine DGA:

English Name: 2-(2-aminoethoxy) ethanol CAS: 929-06-6 Molecular Formula: C4H11NO2 Molecular Weight: 105.14 Density: 1.05g/cm3; Melting Point: -12.5 degrees C; Boiling Point: 218-224 degrees C; Refractive Index: 1.4585-1.4605; Flash Point: 127 degrees C; Diethylenediol Amine DGA is a colorless liquid, slightly sticky and slightly aminous. It can be dispersed in water, alcohols and aromatic olefins, but it is poorly dispersed in aliphatic olefins and ethers.

Performance:

Diethylenediamine DGA is an important solvent and organic raw material. It can dissolve with water, dissolve aromatics and absorb acid gases (H2S and CO2).

Diethylene glycol amine DGA is a primary amine. Compared with other commonly used amines, it has the following characteristics and advantages in the application of metal processing fluids:

1. The dissolution of cobalt metal is much lower than that of other amines, which prolongs the service life of cutting tools and has good corrosion protection for ferrous metals.

2. Dissolution/corrosion of copper metal is much lower than that of other amines.

3. Low corrosion to aluminium stains

4. Higher alkali value reserve capacity and PH stability

5. Low toxicity, low aquatic biological toxicity, not easy to produce nitrite, no sensitization to human body.

6. Easily biodegradable, low bioaccumulation, i.e. high biological stability

7. Low volatility helps to improve the operating environment of the plant. Low pour point and low viscosity improve the operability of the product.

8. Good adaptability to hard water

Use of diethylene glycol amine DGA:

1. It is mainly used as absorbent of acid gas, surfactant and wetting agent, and also as raw material of polymer.

2. As a desulfurizer, it has excellent performance.

3. Diethylene glycol amine DGA can also be used in high and cold conditions, especially in hot, water-deficient and desert areas.
