Ukusebenzisa izinto zezilimo zezilimo zezilimo zezilimo

Izibonelo njengoba i-[Ag (NH3) 2]+, [Cu (NH3) 4] 2+, BF3 · NH3, njll. zonke ziyakwazi ukulungiswa nge-NH3. I-ammonia elikhulu liyisolvent enhle, futhi ngenxa yepolazi yezimo zayo kanye nokutholakala kwezinkanyezi zehydrogen, ikhona imiphumela eningi ngezimo zezulu. Imetal ezinamandla zingathola ihydroxides kusukela ekhulwini, kwenza kube kancane ukuthola ihydrogen ekusikweni kwammonia elikhulu. Kodwa i-ammonia elikhulu kuyathunywa izimetal ukuze kwenze isolusho esibhulukile. Lezi zimetal ammonia elikhulu isolusho zingathola ukukhanya izindlela kanye nokulungisa ukuba izinhlamvu. Ngokwezibonelo, i-sodium liquid ammonia solution: Okokugcina okwenzeka ukuthi isolusho sesimetal ammonia lihlala eluhlaza, lingathola ukukhanya izindlela, kanye nokulungisa ukuba kwenze okukhulu kakhulu kuyadingeka ngenxa yokwenza "ammonia electrons" ekusolweni. Ngokwezibonelo, uma isimetal sase-sodium isolushwa ekusolweni kwammonia elikhulu, iyathola izinhlamvu zakhe zokubeka kanye nokwenza izinyathelo ezikhulu:
Izokwazi ukuthi i-ammonia ethuthukisa kuyinto 800-850 ℃, ngaphansi kwesivikelo se-nickel based catalyst, i-ammonia ingathunyelwa ukuze isetshenziswe ukuze isetshenziswe i-gas elingabonakali elingaba ne-75% H2 kanye ne-25% N2. I-gas ethuthukisiwe ngalesi simo iyinto enhle yokwenza isivikelo esingabonakali esingatholakala kakhulu ekwenzeni izifundo zasezokufudumeza, izifundo zasezokufudumeza, njll.
Ammonia gas ne acetic acid gas zihlukaniswa ekugcineni kwe-420 degrees Celsius, futhi i-acetonitrile ikwakhiwa phansi kwesivikelo.
