Indlela yokuvelisa
Isetyenziswa njengedayi ephakathi, kwaye ikwasetyenziswa kulungiselelo lwe-fluorescent whitening agent agent intermediates, kwaye isetyenziswa kwimveliso ye-fluorescent whitening agent DT.
Indlela yokuvelisa
Ukusebenzisa i-p-chlorophenol njengento eluhlaza, i-2-nitro-p-chlorophenol inokwenziwa nge-nitrate, kwaye emva koko iyancitshiswa ukwenza i-p-chloro-o-aminophenol.
(1) Ukuveliswa kwe-2-nitro-p-chlorophenol: Ukusebenzisa i-p-chlorophenol njengento eluhlaza, i-nitrification nge-nitric acid.Yongeza i-p-chlorophenol ehlanjululweyo ngokukhawuleza kwitanki evuselelweyo kunye ne-30% ye-nitric acid, gcina ubushushu ku-25-30.℃, xuba malunga neeyure ze-2, yongeza umkhenkce ukuze uphole ngaphantsi kwe-20℃, i-precipitate, ihluzo, kwaye uhlambe ikhekhe lokucoca kwi-Congo Red, imveliso ye-2-nitrop-chlorophenol ifunyenwe.
(2) Kukho iindlela ezimbini zokunciphisa i-2-nitro-p-chlorophenol.Enye kukunciphisa nge-sodium disulfide.Okokuqala, i-30% isisombululo se-sodium hydroxide kunye ne-sulfur powder isetyenziselwa ukwenza isisombululo se-sodium disulfide, kunye ne-2-nitro-p-phenol yongezwa ngokulingana nokusabela kwi-95-100.°C, kwaye ukusabela kuphelile.Emva kokucoca okutshisayo, i-filtrate ayithathi hlangothi ngamanzi e-baking soda, ipholile ukuya kwi-20°C, ihluziwe, kwaye ikhekhe lokucoca lihlanjwe ukungathathi hlangothi ukufumana imveliso egqityiweyo 2-nitro-p-chlorophenol.
Okwesibini yindlela yokunciphisa i-hydrogenation.Xa kukho i-nickel catalyst, ukumiswa kwamanzi kwe-2-nitro-p-chlorophenol kulungelelaniswa kwi-pH = 7 kunye ne-sodium dihydrogen phosphate hydrate kunye ne-sodium hydroxide emanzi kwi-hydrogen yoxinzelelo lwe-4.05Mpa kunye nokunciphisa i-Hydrogenation kwi-60.°C. Emva kokuba i-reaction igqityiwe, khulula uxinzelelo, buyisela i-nitrogen, ukushisa kwi-95°C, lungisa i-pH = 10.7 nge-sodium hydroxide, yongeza i-carbon activated kunye nomhlaba we-diatomaceous, uvuselele ngamandla, kunye nesihluzo.Ifiltrate yahlengahlengiswa ukuya kwi-pH=5.2 (20°C) kunye ne-hydrochloric acid egxininisiweyo, ipholile kwi-0°C, yahluzwa, yomiswa, kwaye iphathwa nge-sodium bisulfite.Phinda usebenze amaxesha amane, emva koko distill kwi-2.67kpa, uqokelele amaqhezu malunga nama-80.°C, kwaye uyomise ukuze ufumane imveliso ngesivuno sama-97.7%.
Usetyenziso Olungundoqo
Ukusetyenziswa okuphambili kwe-p-chloro-o-aminophenol njengedayi ephakathi, ukulungiselela i-asidi mordant RH, i-acid complex violet 5RN kunye nedayi esebenzayo, njl., kunye nokulungiselela i-chlorzoxazone yezinto eziluhlaza.
UkuPakisha, ukuGcina nokuThutha
Yikhemikhali eyingozi, kwaye ipakishwe kumagubu entsimbi angama-25kg, kwaye indawo yokugcina impahla ingena umoya, iqondo eliphantsi lobushushu kwaye yomile, kwaye ikhuselwe ekukhanyeni kwelanga.Zigcine kude nemithombo yobushushu bomlilo, kwaye ugcine kwaye uthuthe ngokwahlukeneyo kwiiasidi, ii-oxidants, izongezo zokutya, kunye nee-oxidants.
