Ulwazi lwamanzi amonia
2024.09.02
I-anhydrous ammonia ingama elithambile eliluhlaza elinezingozi ezinamandla. Ammonia, njengoba isilungu esikhula esikhathini esibalulekile, kufanele kwenziwe ngokushesha noma kushisa umoya wokuthutha ammonia wokuthutha umoya ukuze kwenzeke kube lula ukuthuthwa nokugcina. Ammonia iyatholakala kahle ekusolweni namanzi futhi iyenza umthamo ongcolile wokuthutha ammonium hydroxide uma ikusolwa namanzi. I-ammonia eliluhlaza ikhishwa kakhulu ekhishini noma emithwalo yezinsimbi ezinamandla futhi ayikwazi ukuba ishaye nabanye abezinto njengoba i-acetaldehyde, i-acrolein, i-boron, njll. I-ammonia eliluhlaza iyasungwa kakhulu ekwindla, ngezinkinga nokuthutha okunamandla, okwenza kube nokwenzeka kweminyaka engaphezu kweminyaka yezifo zezolimo.
Umbhalo Oluqala:
Ammonia (amoniya engcolile)
Isakhiwo kanye nomfanekiso wemolekula NH3
Izindleko zokwenza kuyadingeka ukwenza isayintetho samonia futhi ukucubungula ukuze kwenze izinto zokwenza amonia okuyisitsha.
Inkambo yeprodukthi: I-ammonia elikhulu liyisiliva elincane olunamandla olunamandla kakhulu futhi linamandla ukuvapheka ekwakhekeni ammonia. Ubukhulu 0.617g/cm3; Isikhala sokuphupha -33.5 ℃, futhi phezulu kwe-77.7 ℃, kungaba yilithi ekhululekile eliluhlaza elinamandla.
Izici ezifanele kanye nezemvelo:
Izibalo zomzimba: NH3 gas ammonia ubunzima obonakalayo (umoya=1): 0.59 Ubunzima bomzimba: 17.04 Liquid ammonia ubunzima obonakalayo (amanzi=1): 0.602824 (25 ℃)
Izindlela zokuthi zibhakabhake: 7664-41-7 Isikhala sokuthi kubhakabhake ngokwesibonelo: 651.11 ℃
Inombolo Yezinto Ezithile: 23003 Umzani Wemitha: 17.03
Izinga lokuyela (℃): -77.7 Umthamo wokuvalelwa: 16% kuya 25%
Izinga lokugcina (℃): -33.4 Ithuluzi elilodwa lomlilo pH: 11.7
Isici esiphakathi kwezinkanyezi kJ (kg · K) ammonia (amafutha) 4.609 ammonia (igesi) 2.179
Isilinganiso se-Vapor: 882kPa (20 ℃)
Ukuphila kweselfu ionization: 2NH3 ↔ NH4+ + NH2-
Kanjalo, ezweni lomoni, i-NH4Cl iyindlela nesibonelo i-asiyidi futhi i-NaNH2 iyindlela nesibonelo i-bheys.
