Hoʻohana ʻia ma ke ʻano he kala waena, a hoʻohana ʻia hoʻi i ka hoʻomākaukau ʻana i nā mea hoʻonaninani fluorescent whitening dye intermediates, a hoʻohana ʻia i ka hana ʻana o ka fluorescent whitening agent DT.

Ke hoʻohana nei i ka p-chlorophenol ma ke ʻano he mea maka, hiki ke hana ʻia ka 2-nitro-p-chlorophenol ma o ka nitration, a laila hoʻemi ʻia e hana i ka p-chloro-o-aminophenol.
(1) Ka hana ʻana o 2-nitro-p-chlorophenol: Ke hoʻohana nei i ka p-chlorophenol ma ke ʻano he maka, ka nitrification me ka waikawa nitric.E hoʻohui mālie i ka p-chlorophenol i hoʻoheheʻe ʻia i loko o ka pahu i hoʻoulu ʻia me 30% nitric acid, mālama i ka mahana ma 25-30.℃, e hoʻoulu no kahi o 2 mau hola, e hoʻohui i ka hau e hoʻomaʻalili ma lalo o 20℃, precipitate, kānana, a holoi i ka kānana keke i Congo Red, loaʻa ka huahana 2-nitrop-chlorophenol.
(2) ʻElua mau ala no ka hōʻemi ʻana i ka 2-nitro-p-chlorophenol.ʻO kekahi e hoʻemi me ka sodium disulfide.ʻO ka mea mua, hoʻohana ʻia ka 30% sodium hydroxide solution a me ka pauka sulfur e hana i ka solution sodium disulfide, a ua hoʻohui ʻia ka 2-nitro-p-phenol e like me ka hana ʻana ma 95-100.°C, a ua pau ka pane.Ma hope o ka kānana wela, hoʻokaʻawale ʻia ka filtrate me ka wai soda baking, hoʻomaha ʻia i 20°C, kānana ʻia, a holoi ʻia ka keke kānana i ka neutrality e loaʻa ai ka huahana 2-nitro-p-chlorophenol.
ʻO ka lua, ʻo ia ke ʻano hoʻemi hydrogenation.Ma ke alo o ka nickel catalyst, ua hoʻoponopono ʻia ka wai hoʻokuʻu o 2-nitro-p-chlorophenol i ka pH=7 me ka sodium dihydrogen phosphate hydrate a me ka sodium hydroxide aqueous solution ma ke kaomi hydrogen o 4.05Mpa a me ka hoʻemi ʻana o ka Hydrogenation ma 60.°C. Ma hope o ka pau ʻana o ka hopena, hoʻokuʻu i ke kaomi, hoʻololi me ka nitrogen, wela i ka 95°C, hoʻololi i ka pH=10.7 me ka sodium hydroxide, hoʻohui i ke kalapona hoʻōla a me ka honua diatomaceous, hoʻoulu ikaika, a kānana.Hoʻoponopono ʻia ka kānana i ka pH=5.2 (20°C) me ka waika hydrochloric concentrated, hoʻoluʻu i 0°C, kānana, maloʻo, a mālama ʻia me ka sodium bisulfite.E hana hou i ka hana ʻehā manawa, a laila distill ma 2.67kpa, e hōʻiliʻili i nā hakina ma kahi o 80°C, a maloʻo iā lākou no ka loaʻa ʻana o ka huahana me ka hua o 97.7%.
ʻO ka noi nui
ʻO ka hoʻohana nui o ka p-chloro-o-aminophenol ma ke ʻano he dye intermediate, no ka hoʻomākaukau ʻana i ka mordant acid RH, acid complex violet 5RN a me nā dyes reactive, etc., a no ka hoʻomākaukau ʻana i ka chlorzoxazone maka.
Puke, Waihona a me ka lawe ʻana
He kemika weliweli ia, a ua hoʻopaʻa ʻia i loko o nā pahu hao 25kg, a ua hoʻokuʻu ʻia ka hale kūʻai, haʻahaʻa a maloʻo, a pale ʻia mai ka lā pololei.E hoʻokaʻawale i nā kumu wela o ke ahi, a mālama a lawe kaʻawale mai nā waikawa, nā mea ʻokiʻoki, nā mea hoʻohui meaʻai, a me nā mea ʻokiʻoki.
