1.Hydrolysis ala: o-nitrochlorobenzene ua hydrolyzed a acidified e ka sodium hydroxide solution.E hoʻohui i 1850-1950 l o 76-80 g / L sodium hydroxide solution i loko o ka ipu hao, a laila hoʻohui i 250 kg o ka o-nitrochlorobenzene i hoʻohui ʻia.Ke wela ia i 140-150 ℃ a ʻo ke kaomi ma kahi o 0.45MPa, e mālama iā ia no 2.5h, a laila e hoʻokiʻekiʻe i 153-155 ℃ a ʻo ke kaomi ma kahi o 0.53mpa, a mālama iā ia no 3h.Ma hope o ka pane ʻana, ua hoʻomaha ʻia i 60 ℃.E hoʻohui i ka wai 1000L a me 60L sulfuric acid concentrated i loko o ka crystallizer ma mua, a laila kaomi i ka hydrolyzate i ʻōlelo ʻia ma luna, a hoʻohui mālie i ka sulfuric acid a hiki i ka ʻulaʻula ʻo Kongo pepa hoʻāʻo i poni, a laila hoʻohui i ka hau e hoʻomaʻalili i 30 ℃, hoʻoulu, kānana, a lulu. mai ka waiʻona makuahine me ka centrifuge e loaʻa ai ka 210kg o-nitrophenol me ka ʻike ma kahi o 90%.ʻO ka hua ma kahi o 90%.ʻO kahi ʻano hoʻomākaukau ʻē aʻe ʻo ka nitratation o ka phenol i loko o kahi hui o ka o-nitrophenol a me ka p-nitrophenol, a laila distillation o ka o-nitrophenol me ka wai.Hana ʻia ka nitrification ma 15-23 ℃ a ʻaʻole pono ka mahana wela ma mua o 25 ℃.
2.Phenol nitration.Hoʻopili ʻia ʻo Phenol e ka waikawa nitric e hana i ka hui ʻana o ka o-nitrophenol a me ka p-nitrophenol, a laila hoʻokaʻawale ʻia e ka distillation mahu.

Hiki ke hoʻohana ʻia ma ke ʻano he waena o ka synthesis organik e like me ka lāʻau lapaʻau, dyestuff, kōkua kaila a me nā mea photosensitive.Hiki ke hoʻohana ʻia e like me kahi hōʻailona pH monochromatic.
Ke ala mālama
ʻO ka hale kūʻai i hoʻopaʻa ʻia i loko o kahi hale kūʻai anuanu a me ka ea.E mālama i ke ahi a me ke kumu wela.Pono e mālama ʻokoʻa ʻia mai ka oxidant, reductant, alkali a me nā kemika edible, a pono e pale ʻia ka waiho ʻana.Hoʻohana ʻia nā kukui pahū a me nā pono ea.ʻAʻole ʻae ʻia ka hoʻohana ʻana i nā mea hana mechanical a me nā mea hana maʻalahi e hana i nā huna huna.Pono e hoʻolako ʻia ka wahi mālama me nā mea kūpono e loaʻa ai ka leakage, ma kahi mamao aku i ke kumu wela, ka ʻā a me ka lapalapa ahi a me nā wahi pahū.
Nānā
Paʻa ka hana no ka hāʻawi ʻana i ka ʻūhā kūloko kūpono.Pono nā mea hana e hoʻomaʻamaʻa kūikawā a mālama pono i nā kaʻina hana.Manaʻo ʻia e ʻaʻahu nā mea hoʻohana ponoʻī i ka huna huna huna huna huna lepo, nā aniani palekana kemika, nā lole hana anti poison penetration a me nā mīkina lima lima.E mālama i ke ahi a me ke kumu wela.ʻAʻole puhi paka ma kahi hana.E hoʻohana i ka ʻōnaehana hoʻoheheʻe pahū a me nā mea hana.E pale i ka lepo.Hōʻalo i ka hoʻopili ʻana me ka oxidant, reducing agent a me ka alkali.I ka lawe ʻana, pono e hoʻouka ʻia a wehe māmā i mea e pale ai i ka pōʻino o ka pūʻolo a me ka pahu.Pono e hoʻolako ʻia nā lako pale ahi o nā ʻano like ʻole a me ka nui a me ka leakage lāʻau lapaʻau pilikia.Loaʻa paha nā mea ʻino i loko o nā pahu hakahaka.
