I-4-Nitrophenol(CAS#100-02-7)
umgangatho
Iikristale ezimthubi ezikhanyayo, ezingenavumba. Inyibilika kancinane emanzini kwiqondo lobushushu begumbi (1.6%, 250 °C). Inyibilika kwi-ethanol, i-chlorophenol, i-ether. I-Soluble kwi-carbonate solutions ye-caustic kunye neentsimbi ze-alkali kunye nephuzi. Inokutsha, kwaye kukho umngcipheko wokudubula okuvuthayo kwimeko yomlilo ovulekileyo, ukushisa okuphezulu okanye ukudibana ne-oxidant. Irhasi enetyhefu ye-ammonia oxide flue ikhutshwa kukwahlulwa kobushushu.
Indlela
Ilungiswa nge-nitrification ye-phenol ibe yi-o-nitrophenol kunye ne-p-nitrophenol, kwaye emva koko yahlula i-o-nitrophenol nge-distillation yomphunga, kwaye inokuthi ifakwe i-hydrolyzed kwi-p-chloronitrobenzene.
sebenzisa
Isetyenziswa njengesigcini sesikhumba. Ikwayinto ekrwada yokwenziwa kwedayi, iziyobisi, njl., kwaye ingasetyenziswa njengesalathisi se-pH se-monochrome, kunye noluhlu lokutshintsha kombala we-5.6 ~ 7.4, ukutshintsha ukusuka kwi-colorless ukuya kumthubi.
ukhuseleko
Impuku kunye nempuku yomlomo LD50: 467mg/kg, 616mg/kg. Inetyhefu! Inomphumo onamandla ocaphukisayo esikhumbeni. Inokufunxwa ngesikhumba kunye nomgudu wokuphefumula. Uvavanyo lwezilwanyana lunokubangela ukwanda kobushushu bomzimba kunye nomonakalo wesibindi kunye nezintso. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, i-agent yokunciphisa, i-alkali, kunye neekhemikhali ezidliwayo, kwaye akufanele zixutywe.
