Ukuzinza: ukuzinza lapho somile, kulula uku-oxidized futhi kube nombala emoyeni oswakeme, okuvutha umlilo uma kunelangabi elivulekile;ukushisa okuphezulu kukhipha i-chloride enobuthi namagesi e-nitrogen oxide.
Indlela Yokukhiqiza
Isetshenziswa njengodayi ophakathi nendawo, futhi ibuye isetshenziswe ekulungiseni udayi we-fluorescent whitening agent, futhi isetshenziswe ekukhiqizeni i-agent emhlophe ye-fluorescent DT.
Indlela Yokukhiqiza
Ngokusebenzisa i-p-chlorophenol njengento eluhlaza, i-2-nitro-p-chlorophenol ingenziwa nge-nitrate, bese incishiswa ukuze yenze i-p-chloro-o-aminophenol.
(1) Ukukhiqizwa kwe-2-nitro-p-chlorophenol: Ukusebenzisa i-p-chlorophenol njengempahla eluhlaza, i-nitrification nge-nitric acid.Faka i-p-chlorophenol egayiwe kancane kancane ethangini elinyakaziswayo ne-30% nitric acid, gcina izinga lokushisa ku-25-30.℃, gqugquzela cishe amahora angu-2, engeza iqhwa ukuze liphole libe ngaphansi kwama-20℃, imvula, isihlungi, futhi ugeze ikhekhe lokuhlunga ku-Congo Red, umkhiqizo we-2-nitrop-chlorophenol utholakala.
(2) Kunezindlela ezimbili zokunciphisa i-2-nitro-p-chlorophenol.Enye iwukunciphisa nge-sodium disulfide.Okokuqala, isisombululo se-30% ye-sodium hydroxide kanye ne-sulfur powder isetshenziselwa ukwenza isisombululo se-sodium disulfide, futhi i-2-nitro-p-phenol yengezwe ngokulingana nokusabela ku-95-100.°C, futhi ukusabela kuphelile.Ngemuva kokuhlunga okushisayo, i-filtrate ayinqunywanga ngamanzi e-baking soda, ipholile ibe ngu-20°C, ihlungiwe, futhi ikhekhe lokuhlunga liyagezwa ukuze lingathathi hlangothi ukuze kutholwe umkhiqizo oqediwe ongu-2-nitro-p-chlorophenol.
Eyesibili indlela yokunciphisa i-hydrogenation.Lapho kukhona i-nickel catalyst, ukumiswa okunamanzi kwe-2-nitro-p-chlorophenol kulungiswa ku-pH = 7 nge-sodium dihydrogen phosphate hydrate ne-sodium hydroxide aqueous solution ngomfutho we-hydrogen we-4.05Mpa kanye nokunciphisa i-Hydrogenation ku-60.°C. Ngemuva kokuthi ukusabela sekuqediwe, khulula ukucindezela, esikhundleni se-nitrogen, ukushisa kuye ku-95°C, lungisa i-pH=10.7 nge-sodium hydroxide, engeza ikhabhoni ecushiwe nomhlaba oyi-diatomaceous, nyakazisa ngamandla, bese uhlunga.Isihlungi silungiswe ukuze sibe pH=5.2 (20°C) nge-concentrated hydrochloric acid, epholile ku-0°C, yahlungwa, yomiswa, futhi yaphathwa nge-sodium bisulfite.Phinda lo msebenzi izikhathi ezine, bese u-distill ku-2.67kpa, uqoqe amafrakshini cishe angama-80.°C, bese uyomisa ukuze uthole umkhiqizo ngesivuno esingu-97.7%.
Isicelo Esiyinhloko
Ukusetshenziswa okuyinhloko kwe-p-chloro-o-aminophenol kufana nodayi ophakathi nendawo, ukulungisa i-acid mordant RH, i-acid complex violet 5RN kanye nodayi abasebenzayo, njll., kanye nokulungisa i-chlorzoxazone eluhlaza.
Ukupakisha, Isitoreji kanye Nezokuthutha
Kuyikhemikhali eyingozi, futhi ipakishwe ezigubhu zensimbi ezingu-25kg, futhi inqolobane ingenisa umoya, izinga lokushisa eliphansi futhi lomile, futhi ivikelekile elangeni eliqondile.Ziqhelelanise nemithombo yokushisa komlilo, futhi ugcine futhi uthuthe ngokuhlukene nama-asidi, ama-oxidants, izithasiselo zokudla, nama-oxidants.
