Intshayelelo
I-2-Amino-4-nitrophenol yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye neenkcukacha zokhuseleko:
Umgangatho:
I-2-Amino-4-nitrophenol yinto eqinileyo kunye neekristale ezityheli ngenkangeleko. Inonyibiliko oluphantsi kwiqondo lobushushu begumbi, iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-ether kunye nebenzene, kwaye inyibilika kancinane emanzini. I-acidic kakhulu kwaye i-oxidizing kakhulu.
Sebenzisa:
I-2-Amino-4-nitrophenol isetyenziswa kakhulu njengento ekrwada yedayi kunye ne-pigments. Ingasetyenziselwa ukulungisa idayi ebonakala ityheli okanye i-orenji, kwaye ingasetyenziselwa ukulungisa i-colorants kwi-pigments kunye nepeyinti.
Indlela:
I-synthesis ye-2-amino-4-nitrophenol inokufumaneka ngokuphendula kwe-phenol kunye ne-nitric acid ukwenza i-p-nitrophenol, kwaye emva koko ngokuphendula ngamanzi e-ammonia ukwenza i-2-amino-4-nitrophenol. Indlela ethile yokudibanisa kunye neemeko zokusabela ziya kwahluka, kwaye indlela efanelekileyo yokudibanisa inokukhethwa ngokweemfuno.
Ulwazi ngoKhuseleko:
I-2-Amino-4-nitrophenol yikhompawundi ecaphukisayo kunye neyityhefu, kwaye ukuvezwa okanye ukuphefumla uthuli lwayo kunokubangela ukucaphuka kwamehlo, ulusu, kunye nendlela yokuphefumla. Izixhobo ezifanelekileyo zokuzikhusela zifanele zinxitywe xa usebenzisa okanye uphathwa yaye ukunxibelelana ngokuthe ngqo kufanele kuphetshwe. Isenokuba yingozi kokusingqongileyo, kwaye inkunkuma kufuneka ilahlwe ngokufanelekileyo kwaye kufuneka kulandelwe iinkqubo ezifanelekileyo zokusebenza zokhuseleko.
