application area 
Surfactant
As a surfactant raw material, it can produce various high-performance amphoteric imidazoline surfactants for shampoo, bath liquid, personal and industrial cleaning agents. At the same time, it can also produce cationic imidazoline surfactants with good anti-corrosion and corrosion inhibition effects, strong emulsifying ability, and good dispersibility.  
Alkyl imidazoline series amphoteric surfactants. It has excellent foam and wettability, stability to pH change, low toxicity, complete biodegradation, and no irritation to skin and eyes. Components used for baby shampoo. Also used in cosmetics. Acylation of ethylenediamine with fatty acids to produce amides, which are then reacted with epoxyethane to produce. It can also be prepared by reacting fatty acids with aminoethyl ethanolamine. Various alkyl imidazoline derivative series surfactants can be prepared by sulfonation and sulfation reactions of alkyl imidazoline and its hydrolysis product amide amine.  
Inhibitor
In June 1971, a research group composed of China Southern Refining, Nanjing Institute of Chemical Technology, and Sichuan Petroleum Refining Research Institute was tasked with improving the solubility of 1011 corrosion inhibitor. Eventually, they selected hydroxyethyl ethylenediamine as one of the raw materials to synthesize corrosion inhibitor 1017. During the synthesis process, hydroxyethyl ethylenediamine is used to react with oleic acid to synthesize hydroxyethyl imidazoline. The product is then reacted with epichlorohydrin to produce polyoxyalkylimidazoline, which is finally compounded with 33% oleic acid to form polyoxyalkylimidazoline oleate. In practical use, it is called 1017-5 corrosion inhibitor, which is suitable for environments with pH 8-9. It is a corrosion inhibitor with good oil solubility and high slow-release rate. Compared with French PR, its slow-release rate for iron ions is similar, but at the phase transition site, which is the most severely corroded area, it is significantly higher than French PR.  
curing agent
Commonly used as a curing agent and wetting agent, it can be widely used for 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 bonding non-metallic and metallic materials, and can also be used for casting mechanical, electrical components, and cable joints. The active period of the curing agent is about 25 minutes at 20 ℃, and the curing speed is about twice as slow as ethylenediamine, and it has a plasticizing effect.
CO ? absorbent
Like flue gas desulfurization, organic amine washing has always been the preferred method for capturing and separating CO2 from flue gas, and this technology was first used in the 19th century. Recent studies have shown that under the same concentration conditions, hydroxyethyl ethylenediamine has a greater ability to absorb carbon dioxide than ethanolamine, but its desorption ability is weaker, resulting in better absorption of carbon dioxide. AEEA decomposes during the capture of carbon dioxide, producing proton ammonia, difficult to adsorb amino formate salts, and easily dissociated HCO32- and CO32-.  
pharmaceutical production
As an organic synthesis intermediate, it is the side chain of the anticancer drug Mitoxantrone. After synthesizing 1,4-5,8-tetrahydroxyanthraquinone, adding hydroxyethyl ethylenediamine dropwise and stirring continuously can synthesize the crude product of mitoxantrone, which is a paste like viscous liquid.  [


Uses: It can be used as the raw material for the production of light stabilizers and vulcanizing accelerators in the paint and coating industry, the metal ion chelating agent generated after the carboxylation of amino groups, the detergent for cleaning zinc cuprum (copper nickel zinc alloy) coins to prevent browning, the lubricating oil additive (can be used directly with methacrylic acid copolymer as a preservative and oil stain dispersant), synthetic resins such as water-based lotion coatings, paper sizing agent and hair spray, etc. Used for the production of dyes, resins, rubber, flotation agents, insecticides, surfactants for shampoo, lubricants, oilfield buffers, resin synthesis, textile auxiliaries, imidazoline amphoteric surfactants, etc. It also has certain applications in petrochemical and other fields.
Corrosion inhibitor 1017 is used for the production of dyes, resins, rubber, flotation agents, insecticides, surfactants, and formulated for petrochemical production. This product is an excellent low toxicity room temperature curing agent for epoxy resin, significantly superior to ethylenediamine. This product is compatible with epoxy resin and widely used for bonding various metal and non-metal components, preparing anti-corrosion epoxy coatings, casting cable joints, and other mechanical and electrical parts.
