Diglycolamine Application scenarios
1. Industrial Gas Treatment
Acidic Gas Absorbent/Desulfurizer
Used for removing acidic gases such as H₂S and CO₂ from process gases in oil and gas, coal chemical, etc., with excellent performance. Its solution can be used stably in high-altitude, hot, and water-scarce regions (such as deserts).
2. Chemical Production and Synthesis
Key Raw Materials or Intermediates
• Polymer Raw Materials: Used as amine curing agents or chain extenders for epoxy resins, improving the performance of coatings, adhesives, and other products.
• Morpholine Production: Can be used as a raw material for the production of morpholine or as a co-production with it.
• Synthetic Surfactants: A basic raw material for the synthesis of nonionic, cationic, and amphoteric surfactants (such as alkanolamides and betaine), used in the daily chemical and cleaning industries.
• Polyurethane Catalysts: An important raw material for the production of low-odor polyurethane foaming catalysts.
3. Personal Care & Daily Chemicals
Functional Additives
In cosmetics (such as shampoos and conditioners), they are used as moisturizers, viscosity modifiers, and pH adjusters, improving product stability and skin feel. Related patents show that their derivatives (such as diethylene glycolamine acetamide) have a synergistic moisturizing effect.
4. Agriculture
Pesticide Formulation Adjuvants
Used as neutralizers, synergists, or solvents in pesticides. For example, used in the preparation of high-content flufenoxuron (herbicide) aqueous solutions.
5. Other Industrial Applications
Metalworking Fluid Components
In metalworking fluids, compared to other amines, they exhibit lower leaching corrosion to metals such as cobalt and copper, and possess better alkalinity reserve and pH stability.
