Product Introduction:

Aminoethylethanolamine, also known as 2-(2-Aminoethylamino)ethanol or curing agent No. 1 or AEEA, is an organic base. Molecular formula C4H12ON2, its molecule contains both active amino and hydroxyl groups, has strong polarity, and its chemical properties are similar to ethylenediamine.

At the same time, it also has the chemical properties of ordinary alcohols and has multifunctionality. It can react with inorganic acids, organic acids and various organic compounds to form salts, aminolysis, esterification and condensation at the same time to generate various derivative products.

Appearance is light yellow to yellow viscous liquid, non-irritating. It is hygroscopic, strongly alkaline, and has a slight ammonia odor. Soluble in water and ethanol, easy to absorb moisture, can absorb carbon dioxide and water from the air, and has good compatibility with epoxy resin.

Similar to ethylenediamine, aminoethylethanolamine can be cyclized with glyoxal to synthesize piperazine derivatives. For example, some studies have used imine reductases (IREDs) catalyzed by aminoethylethanolamine and ethylene glycol under mild conditions. Efficient synthesis of N-hydroxyethylpiperazine from dialdehyde.

The volatility is smaller than that of ethylenediamine, the viscosity is slightly larger than that of ethylenediamine, and the toxicity is 6~7 times lower than that of ethylenediamine. Commonly used as epoxy resin curing agent, it has the characteristics of low toxicity and room temperature curing.

Aminoethylethanolamine is mainly used as a raw material for cationic and zwitterionic surfactants. It can also be used as epoxy resin curing agent and raw material for other fine chemical products.

Product Usage:

Aminoethylethanolamine (AEEA) can be used as a raw material for the production of light stabilizers and vulcanization accelerators in the paint and coating industry, and the carboxylation of amino groups to generate metal ion chelating agents.

As a detergent for cleaning zinc cupronickel (copper-nickel-zinc alloy) coins to prevent browning, lubricating oil additives (can be directly used with methacrylic acid copolymers as preservatives and oil dispersants), synthetic resins such as water-based emulsion coatings, paper sizing agents and hair spray, etc.

It also has certain uses in petrochemical and other aspects.

used as Surfactant

Aminoethylethanolamine can be used as a raw material for surfactants to produce amphoteric imidazoline surfactants with excellent performance in various shampoos, bath liquids and personal and industrial cleaning agents.

At the same time, it can also produce cationic imidazoline surfactants with good anti-corrosion and corrosion inhibition effect, strong emulsifying ability and good dispersing performance.

Alkyl imidazoline series amphoteric surfactants. It has excellent foaming and wetting properties, stability to pH changes, low toxicity, complete biodegradation, and no irritation to skin and eyes. Components for baby shampoos.

Also used in cosmetics. It is obtained by acylation of ethylenediamine with fatty acid to generate amide, which is then reacted with ethylene oxide. It can also be obtained by the reaction of fatty acids and aminoethyl ethanolamine. A variety of alkyl imidazoline derivatives series of surfactants can be prepared by sulfonation and sulfation reaction of alkyl imidazoline and its hydrolyzed amidoamine.

used as Curing Agent

Aminoethylethanolamine is also commonly used as a curing agent and a wetting agent, and can be widely used in bonding various metals and non-metals, preparing anti-corrosion epoxy coatings and chemical grouting agents.

As a curing agent, it is mainly compounded with epoxy resin, such as for non-metal and metal bonding, and can also be used for casting of machinery, electrical parts and cable joints.

The active period of the curing agent is about 25 minutes at 20 °C, the curing speed is about twice slower than that of ethylenediamine, and it has a plasticizing effect.

for Synthesizing Corrosion Inhibitors

Corrosion inhibitor 1017 was synthesized with aminoethylethanolamine as one of the raw materials. In the synthesis process, 2-(2-Aminoethylamino)ethanol was used to react with oleic acid to synthesize hydroxyethyl imidazoline, the product was then reacted with propylene oxide to generate polyoxyalkyl imidazoline, and finally 33% oleic acid was added to compound into polyoxyalkyl group imidazoline oleate.

In actual use, it is called 1017-5 corrosion inhibitor. This corrosion inhibitor is suitable for the environment with PH of 8-9. It is a corrosion inhibitor with good oil solubility and high slow release rate.

Compared with French PR, its slow release rate of iron ions is similar, and at the phase transition position, that is, the most severely corroded position, it is significantly higher than that of French PR.

Used as CO₂ Absorbent

Like flue gas desulfurization, organic amine scrubbing has been the method of choice for CO2 capture from flue gas, and the technology began to be used in the nineteenth century.

Recent studies have shown that under the same concentration conditions, aminoethylethanolamine has a higher carbon dioxide absorption capacity than ethanolamine, but its desorption capacity is weaker, so its carbon dioxide absorption effect is better.

AEEA decomposes in the process of capturing carbon dioxide and produces: proton ammonia, hard-to-desorb carbamate, easily dissociated HCO32- and CO32-, etc.

for Pharmaceutical Production

As an intermediate in organic synthesis, aminoethylethanolamine is the side chain of the anticancer drug mitoxantrone. After synthesizing 1,4,5,8-tetrahydroxyanthraquinone, adding 2-(2-Aminoethylamino)ethanol dropwise and stirring continuously, the crude product of mitoxantrone can be synthesized, and the product is a paste-like viscous liquid.
