taiao
He wai kōwhai, he wai mātotoru, he kakara haukini, he mura, he kaha te kawakore. Ka wairewa ki te wai, ki te acetone, ki te benzene, ki te ether, ki te methanol, me ētahi atu, kāore e wairewa ki te n-heptane, ā, ka waikura ki te parahi me ōna koranu. Te ira rewa -35℃. Te ira koropupū 207℃. Te mātotoru whanaunga o. 9586. Te ira mura 94℃. Te taupū whakaata 1. 4810. He rite te tauhohenga o tēnei hua ki ngā amine tuarua, ā, he ngāwari ki te tauhohe ki ngā momo matū. He whānuitia ngā whakamahinga o ōna hua.

Tikanga whakarite
Ka taea te whiwhi mā te whakaamonia o te dichloroethane. Ka tukuna te 1,2-Ethyl chloride me te wai ammonia ki roto i tētahi tauhohenga ngongo hei mahi i tētahi tauhohenga whakaamonia pēhanga wera i te pāmahana o te 150-250°C me te pēhanga o te 392.3kPa. Ka whakakorengia te otinga tauhohenga ki te kawakore hei whiwhi i ngā amine kore utu kua whakaranua, ka kukūhia i te wā e tangohia ana te konutai chloride. Kātahi ka whakawetohia te hua mata i raro i te pēhanga kua whakaitihia, ā, ka hopukina te wāhanga i waenga i te 195 me te 215°C hei whiwhi i te hua kua oti. Ka hangaia ngātahitia e tēnei tikanga te ethylenediamine, te triethylenetetramine, tetraethylenepentamine me te polyethylenepolyamine i te wā kotahi. Ka taea te whiwhi mā te whakahaere i te pāmahana o te pourewa whakaweto hei whakaweto i te ranunga amine me te hopu i ngā wāhanga rerekē hei wehenga.

whakamahi
Ko te nuinga o te wā ka whakamahia tēnei hua hei whakarewa me te takawaenga hanga rauropi, ā, ka taea te whakamahi hei hanga i ngā kaihoko whakaora kapia epoxy, ngā kaihoroi hau (mō te tango CO2), ngā tāpiringa hinu whakahinuhinu, ngā emulsifier, ngā matū whakaahua, ngā surfactants, me ngā kaihoko whakaoti kakahu. , whakarei pepa, kaihoko whakahiato aminocarboxylic, kaihoko chelating whakarewa, kaihoko tohatoha hiko hydrometallurgy me te cyanide-free, kaiwhakamārama, me te kapia whakawhiti katote hangai me te kapia polyamide, me ētahi atu.
