Intshayelelo
I-4-Nitro-3-trifluoromethylaniline, eyaziwa ngokuba yi-TNB (i-Trinitrofluoromethylaniline), i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Imhlophe ukuya kwiikristale ezityheli ezikhanyayo okanye umgubo
-Ukunyibilika: kunyibilika kancinane emanzini, kunyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-acetone, njl.
-Uzinzo: Uzinzile kukukhanya, ubushushu kunye nomoya, kodwa uchaphazeleka kukufuma kunye nokudubula
Sebenzisa:
- I-4-Nitro-3-trifluoromethylaniline isetyenziswa ngokubanzi njengenxalenye yabaqalisi kunye neziqhumane, umzekelo, ingasetyenziselwa indawo ye-TNT (trinitrotoluene). Inamandla aphezulu okuqhuma kunye nokuzinza kwintsimi yeziqhushumbisi.
Indlela:
- Ukusuka kwi-aniline, i-trifluoromethanesulfonic acid iqala ukusabela nge-cuprous bromide ukwenza i-trifluoromethylaniline. Emva koko, i-trifluoromethylaniline iphendulwa nge-nitric acid, i-nitrobenzene yongezwa, kwaye emva kokunyangwa kwe-nitrite acid, i-4-nitro-3-trifluoromethylaniline ekugqibeleni ifunyenwe.
Ulwazi ngoKhuseleko:
- I-4-Nitro-3-trifluoromethylaniline sisithako esiqhumayo kwaye sithathwa njengesiqhushumbisi kwaye kufuneka sisetyenziswe ngobunono.
-Xa uphethe kwaye ugcina, kunqanda ukuvusa nakuphi na ukuvutha okanye iintlantsi zombane.
- Kulumkele ukudibana nezinto ezinokutsha, ii-oxidants kunye ne-alkaline enokuthi iqalise ukusabela okunokuba yingozi.
- Ukuphefumla, ukungenwa, okanye ukudibana nolusu kunye namehlo kunokuba neziphumo eziyingozi, ezifuna ukunxitywa kwezixhobo ezifanelekileyo zokuzikhusela xa usebenza.
