The Use of Ethylene Amine

Due to being a series of products, they have similarities in nature and can be substituted for each other in certain industries. Ethylene amine is mainly used as a surfactant, epoxy resin curing agent, pesticide raw material, pharmaceutical raw material, washing aid, polyamide resin, papermaking aid, lubricating oil additive, water treatment agent raw material, dye fixing agent, adhesive raw material, etc.

Ethylenediamine is mainly used in the production of pesticides (such as manganese zinc, zinc, amine, insecticides, herbicides, and fungicides), surfactants (such as bisstearamide, alkylimidazoline, and bisamide, which are synthesized with ethylene oxide and epichlorohydrin to form non-ionic surfactants), epoxy resin curing agents (such as polyamide resin, epoxy curing agent, hydroxyethyl ethylenediamine, etc.), washing aids (such as ethylenediaminetetraacetic acid and its sodium salt series chelating agents), pharmaceutical raw materials (such as aminophylline, chlorhexidine, nasal eye net, insecticide, etc.), water treatment agents (ethylenediaminetetramethylphosphonate, ethylenediaminetetraphosphonic acid, etc.) Corrosion inhibitors (cyclic amine polymers), dye fixing agents, photographic material fixing solutions, and lubricant additives. Pesticides, chelating agents, surfactants, and epoxy curing agents account for over 70% of the dosage.

Diethylenetriamine is mainly used in conjunction with epichlorohydrin and adipic acid to produce wet strength agents - a papermaking additive that mainly improves the strength of wet paper for processing or use; Other applications include soft films (alkylimidazoline, softener), epoxy curing agents, corrosion inhibitors, printing and dyeing auxiliaries, water treatment agents (diethylenetriamine pentamethylphosphonic acid), pesticide bacterial toxins, etc.

Triethylenetetramine is mainly used for two purposes: epoxy curing agent (including polyamide resin) and ashless dispersant. Other uses include asphalt emulsifier, water treatment, corrosion inhibitor, surfactant, etc.

Tetraethylenepentamine is mainly used in the production of ashless dispersants, and other uses include asphalt emulsifiers, demulsifiers, epoxy curing agents, ion exchange resins, filter aids, etc.
