chemical property
colorless, light yellow transparent viscous liquid. it is hygroscopic, strongly alkaline and slightly ammonia it is miscible with water and alcohol, slightly soluble in ether.
production method
it is obtained by the reaction of ethylenediamine with ethylene oxide.
purpose
it is used to produce dye, resin, rubber, flotation agent, insecticide and surfactant, and the prepared inhibitor 1017 is used in petrochemical production. the product is a good low toxicity room temperature curing agent for epoxy resin, which is obviously superior to ethylenediamine. it is widely used for bonding various metal and non-metal parts, preparing anticorrosive epoxy coating, casting cable joints and other mechanical and electrical parts.
used in shampoo, lubricant, oilfield buffer, resin synthesis, textile assistant, imidazoline amphoteric surfactant, etc
used as curing agent for plastics
for organic synthesis
