Description

Diethylenetriamine is a versatile, high-purity aliphatic amine with the CAS number 111-40-0, serving as a critical building block and intermediate in numerous industrial chemical syntheses. Its trifunctional nature, featuring two primary and one secondary amine group, makes it an essential component for creating polymers, chelating agents, and epoxy curing systems. This product is particularly valuable for manufacturers in the epoxy resin, textile, paper, and water treatment industries seeking reliable performance and consistent quality.

Application

• Epoxy Curing Agent: A key hardener for epoxy resins, providing excellent mechanical properties and chemical resistance in coatings, adhesives, and composites.
• Chelating Agent Precursor: Used in the synthesis of EDTA (ethylenediaminetetraacetic acid) analogs and other sequestrants for water treatment, detergents, and agriculture.
• Polyamide Resin Production: Acts as a monomer for producing polyamide resins used in hot-melt adhesives, printing inks, and flexible packaging.
• Gas Purification: Employed as an absorbent in gas scrubbing processes to remove acidic components like CO₂ and H₂S.
• Textile & Paper Chemicals: Serves as an intermediate for fabric softeners, dye fixatives, and wet-strength resins for paper.
• Pharmaceutical & Agrochemical Intermediate: A valuable building block in the synthesis of certain active pharmaceutical ingredients (APIs) and herbicides.
• Corrosion Inhibitor: Formulated into additives for fuels, lubricants, and cooling systems to protect metal surfaces.
• Asphalt Emulsifier: Used in the production of cationic asphalt emulsions for road construction and maintenance.

Quality Control

Our Diethylenetriamine is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as assay, color, water content, and specific impurity profiles. Our quality commitment aligns with global standards, including REACH compliance for the European market.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
