Mokhoa oa Tlhahiso
E sebelisoa e le dae ea mahareng, hape e sebelisoa ha ho lokisoa li-intermediates tsa fluorescent whitening agent, mme e sebelisoa ho hlahiseng moemeli oa fluorescent whitening DT.
Mokhoa oa Tlhahiso
Ho sebelisa p-chlorophenol e le thepa e tala, 2-nitro-p-chlorophenol e ka etsoa ka nitration, ebe e fokotsoa ho etsa p-chloro-o-aminophenol.
(1) Tlhahiso ea 2-nitro-p-chlorophenol: Ho sebelisa p-chlorophenol e le lisebelisoa tse tala, nitrification ka nitric acid.Eketsa p-chlorophenol e qhibilihisitsoeng butle-butle ka tanka e tsositsoeng ka 30% ea nitric acid, boloka mocheso ho 25-30.℃, tsosa ka lihora tse ka bang 2, eketsa leqhoa ho pholile ka tlase ho 20℃, precipitate, filthara, 'me u hlatsoe kuku ea filthara ho Congo Red, sehlahisoa sa 2-nitrop-chlorophenol se fumanoa.
(2) Ho na le mekhoa e 'meli ea ho fokotsa 2-nitro-p-chlorophenol.E 'ngoe ke ho fokotsa ka sodium disulfide.Taba ea pele, 30% ea tharollo ea sodium hydroxide le phofo ea sebabole e sebelisoa ho etsa tharollo ea sodium disulfide, 'me 2-nitro-p-phenol e eketsoa ka tekanyo ea ho itšoara ka 95-100.°C, 'me karabelo e felile.Kamora ho hloekisoa ho chesang, filtrate ha e na letho ka metsi a ho baka, a pholile ho isa ho 20°C, e tlhotliloeng, 'me kuku ea sefa e hlatsuoa ho se nke lehlakore ho fumana sehlahisoa se felileng sa 2-nitro-p-chlorophenol.
Ea bobeli ke mokhoa oa ho fokotsa hydrogenation.Boteng ba nickel catalyst, ho emisoa ka metsi ha 2-nitro-p-chlorophenol ho fetoloa ho pH = 7 ka sodium dihydrogen phosphate hydrate le sodium hydroxide aqueous solution ka khatello ea hydrogen ea 4.05Mpa le phokotso ea Hydrogenation ho 60.°C. Ka mor'a hore karabelo e phethoe, lokolla khatello, nkela sebaka ka nitrogen, mocheso ho 95°C, fetola pH = 10.7 ka sodium hydroxide, eketsa k'habone e kentsoeng le lefats'e la diatomaceous, tsosa ka matla, 'me u sefa.Filtrate e fetotsoe ho pH=5.2 (20°C) ka concentrated hydrochloric acid, e pholileng ho 0°C, e tlhotliloeng, e omisitsoe, 'me e phekoloe ka sodium bisulfite.Pheta ts'ebetso ka makhetlo a mane, ebe u lahla ho 2.67kpa, bokella likaroloana tse ka bang 80.°C, 'me u li omise ho fumana sehlahisoa ka lihlahisoa tsa 97.7%.
Kopo e ka Sehloohong
Tšebeliso e ka sehloohong ea p-chloro-o-aminophenol ke e le dae e bohareng, bakeng sa ho lokisoa ha acid mordant RH, acid complex violet 5RN le lidae tse sebetsang, joalo-joalo, hammoho le ho lokisa chlorzoxazone e tala.
