Used mainly in

Epoxy resin curing agent: As a low toxicity room temperature curing agent with better performance than ethylenediamine, it is widely used for bonding metal/non-metal parts, anti-corrosion coatings, cable joint casting, etc

Surfactant raw materials: used for the production of cationic and zwitterionic surfactants, such as imidazolines

Industrial additives:

Shampoo, lubricant, oilfield buffer

Synthetic intermediates of dyes, rubber, plastics, flotation agents, insecticides

Corrosion inhibitors (such as corrosion inhibitor 1017) are used in the petrochemical industry

Other applications:

Metal ion chelating agent precursor

Lubricant additive (copolymer with methacrylic acid)

Synthesis lines:

In industry, it is mainly produced through the reaction of ethylenediamine and ethylene oxide

1. Raw materials: Ethylene diamine+Ethylene oxide

2. Reaction conditions: Typically, the addition reaction is carried out in a solvent (such as an alcohol) with controlled temperature and pressure

3. Reaction formula: \ ceH2N − CH2 − CH2 − NH2+CH2 − CH2 −>[certain conditions] H2N − CH2 − CH2 − NH − CH2 − CH2 − OH \ ceH2N − CH2 − CH2 − CH2 − NH2+CH2 − CH2 −>[certain conditions] H2N − CH2 − CH2 − NH − CH2 − CH2 − OH (epoxide ring opening addition to an amino group of ethylenediamine)

4. Product: N - (2-hydroxyethyl) ethylenediamine (111-41-1)

This method has mature technology, controllable selectivity, and is suitable for large-scale production.
