okike
Yellow hygroscopic transperent viscous mmiri mmiri na pungent amonia isi, flammable na ike alkaline. Soluble n'ime mmiri, acetone, benzene, ether, methanol, wdg, na-adịghị edozi na n-heptane, na corrosive na ọla kọpa na alloys. Ebe mgbaze -35 ℃. Ebe esi nri 207 ℃. Njupụta nke ikwu o. 9586. Ọkụ ọkụ 94 ℃. Refractive index 1. 4810. Ngwaahịa a nwere reactivity nke abụọ amines na-adị mfe meghachi omume na a dịgasị iche iche nke ogige. Ihe mmepụta ya nwere ọtụtụ ojiji.

Usoro nkwadebe
Enwere ike nweta ya site na amoniation nke dichloroethane. A na-eziga 1,2-Ethyl chloride na mmiri amonia n'ime reactor tubular iji mee mmeghachi omume ammoniation na-ekpo ọkụ na okpomọkụ nke 150-250 ° C na nrụgide nke 392.3kPa. A na-ewepụ ihe ngwọta mmeghachi omume na alkali iji nweta amines n'efu, nke na-etinye uche mgbe ọ na-ewepụ sodium chloride. A na-ekpochapụ ngwaahịa crude n'okpuru nrụgide belatara ma na-egbochi akụkụ dị n'etiti 195 na 215 Celsius iji nweta ngwaahịa emechara. Usoro a na-ejikọta ethylenediamine, triethylenetetramine, tetraethylenepentamine na polyethylenepolyamine n'otu oge. Enwere ike nweta ya site na ịchịkwa okpomọkụ nke ụlọ elu distillation iji kpochapụ ngwakọta amine na nkwụsịtụ dị iche iche maka nkewa.

jiri
A na-ejikarị ngwaahịa a eme ihe dị ka ihe mgbaze na organic synthesis intermediate, na enwere ike iji kwadebe epoxy resin curing agents, gas purifiers (maka CO2 mwepụ), mmanụ mmanu mmanu mmanu, emulsifiers, foto chemicals, surfactants, na ákwà finishing agents. , akwụkwọ nkwalite, aminocarboxylic complexing agent, metal chelating agent, metal hydrometallurgy na cyanide-free electroplating diffusion agent, brightener, and synthetic ion exchange resin na polyamide resin, wdg.
