Diethanolamine – Manufacturer, Supplier & Exporter | DPRJ Universal

What is the primary use of Diethanolamine?

The primary industrial use of Diethanolamine (DEA) is as a surfactant compound, an emulsifying agent, and an industrial gas scrubber. It is heavily utilized to isolate acid components CO₂ and H₂S from process gas streams, create everyday detergents/shampoos, and formulate metal treatment inhibitors.

What is the molecular weight and chemical formula of Diethanolamine?

The chemical formula for Diethanolamine is C₄H₁₁NO₂. Its exact molecular weight is 105.14 g/mol.

How is Nitrobenzene or Diethanolamine prepared industrially?

Diethanolamine synthesis is carried out by reacting ethylene oxide with aqueous ammonia. This chemical process generates MEA, DEA, and TEA concurrently, which are subsequently split via fractional distillation columns to yield targeted specs such as diethanolamine solution 85% and premium 99% purity variants.

What is the Diethanolamine structure and functional group?

The Diethanolamine structure features a central secondary amine core bonded to two distinct hydroxyethyl lines. It features both amine and alcohol functional groups, offering versatile reactivity profiles for industrial synthesis.

What is the difference between Diethanolamine DEA and Triethanolamine TEA?

Diethanolamine features a secondary nitrogen structure, whereas Triethanolamine represents a tertiary structural amine. This impacts their overall chemical properties, alkalinity ratings, and performance limits within target emulsifier or gas sweetening setups.

What are the key physical properties, such as boiling point and density?

High-purity Diethanolamine properties include a boiling point of 268.8 C, a density profile of 1.09 g/mL at 20 C, and a low melting point of 28 C. It commonly shifts between a transparent viscous fluid and clear crystal forms depending on the local storage temperature environment.

How is Diethanolamine used in skincare and shampoo, and is Cocamide DEA safe?

Various amine mixtures like Cocamide DEA and diethanolamine lauryl sulfate serve as lather boosters and texturizers in shampoo brands. When manufactured correctly to avoid unreacted free amines, Cocamide DEA is fully safe for commercial wash-off personal care cosmetics.

Is Diethanolamine hazardous and what are the handling precautions?

Yes, Diethanolamine exhibits chemical hazards and is classified as an irritant capable of producing severe eye damage. Material handling processes require proper personal protective equipment (PPE), active ventilation setups, and appropriate diethanolamine storage temperature limits to prevent solidification.

What is the common name or trade classification for Diethanolamine?

While commonly designated as DEA, DEOA, or bis(2-hydroxyethyl)amine, it is tracked in standard custom logistics using the dedicated diethanolamine hs code (HSN code) 29221200.
