Hana hana:
1. Hana ʻia ia mai ka naphthalene ma o ka sulfonation a me ka hui alkali.ʻO ke ʻano o ka sulfonated alkali fusion he ʻano hana hoʻohana nui ʻia ma ka home a ma waho, akā he koʻikoʻi koʻikoʻi, ke kumu kūʻai kiʻekiʻe, a me ka hoʻohana ʻana i ka oxygen biological kiʻekiʻe i ka wai ʻino.ʻO ke ʻano 2-isopropylnaphthalene i hoʻomohala ʻia e ka American Cyanamide Company e hoʻohana ana i ka naphthalene a me propylene ma ke ʻano he kumu waiwai e hana ai i ka 2-naphthol ma ke ʻano he huahana o ka acetone.Ua like kēia ʻano me ka hana ʻana o ka phenol ma ke ʻano cumene.Ka helu ʻai meaʻai maka: naphthalene i hoʻomaʻemaʻe ʻia 1170kg/t, ʻakika sulfuric 1080kg/t, paʻakai paʻakai 700kg/t.

2.1) ʻano hoʻoheheʻe alkali sulfonated.E hoʻokomo i ka naphthalene i hoʻomaʻemaʻe ʻia i loko o ka ipu sulfonation a me ka wela (hoʻoheheʻe) i 140 ° C.Hoʻohui i 1.085 manawa (molar ratio) concentrated sulfuric acid i loko o 20 mau minuke, e hoʻonui i ka mahana, a mālama iā ia ma 160-164 ° C no 2.5 mau hola.Hoʻopau ka hopena i ka hiki ʻana o ka 2-naphthalenesulfonic acid i ka 66% a ʻoi aku paha a ʻo ka nui o ka acidity he 25%-27%.Hoʻopili ʻia ka sulfonate i loko o kahi ipu wai hydrolysis ma 140-150 ℃ no 1h.A laila, i loko o ka ipu hao, e hoʻokaʻawale me ka sodium hydrogen nitrite solution ma 80-90°C a hiki i ka ʻulaʻula ʻole o ka pepa hōʻike Congo.E hoʻohana i ka mahu a me ka ea e hoʻokuke aku i ke kinoea SO2, maʻalili a hiki i 30-40°C a laila kānana hoʻoheheʻe, holoi me 10% wai paʻakai, a laila kānana hoʻoheheʻe e loaʻa ka sodium 2-naphthalenesulfonate.E kau i ka sodium hydroxide i loko o kahi ipu hoʻoheheʻe alkali, wela (melt) i 290 ° C, a hoʻohui i ka sodium 2-naphthalenesulfonate ma kahi o 3 mau hola a hiki i ka 5% -6% ka waihona alkali manuahi.Ma hope, mālama ʻia ma 320-330 ° C no 1 hola.Hoʻoheheʻe ʻia ka hoʻoheheʻe alkali i loko o ka wai a hāʻawi ʻia iā SO2 ma 70-80°C a hiki i ka phenolphthalein ke kala ʻole.E hoʻohui i ka wai e hoʻolapalapa a holoi, wehe i ka sodium sulfite, a laila hoʻomaloʻo a hoʻoheheʻe ʻia ma lalo o ke kaomi hoʻemi e loaʻa ai ka huahana i hoʻopau ʻia.ʻO 73%-74% ka nui o ka hua.
2) 2-isopropylnaphthalene ala.ʻO Chemicalbook, e hoʻohana ana i ka naphthalene a me ka propylene ma ke ʻano he mea maka, hoʻopuka hou i ka 2-naphthol i ka manawa like me kahi huahana o ka acetone.

3. ʻO ke ʻano o ka hoʻomākaukau ʻana, ʻo ia ka hoʻohui ʻana i ka ʻakika sulfuric i ka naphthalene hehee ma 140°C, hana i ka sulfonation ma 162～164°C, hydrolyze ka sulfonate, puhi i ka naphthalene manuahi, a hana me ka sodium sulfite e hana i ka 2-naphthalenesulfonic acid sodium paʻakai. .Hoʻoheheʻe ʻia ka paʻakai sodium paʻa a me ka sodium hydroxide ma 285-320 ° C, a laila mālama ʻia ma 320-330 ° C no 1 hola.Hoʻoheheʻe ʻia ka hoʻoheheʻe alkali a hāʻawi ʻia i loko o ka sulfur dioxide no ka acidification e loaʻa ai kahi huahana maʻemaʻe, i holoi ʻia a hoʻomaʻemaʻe ʻia a laila distilled e loaʻa ka huahana.

4. ʻO ke ʻano hoʻoheheʻe alkali Sulfonation E hoʻokomo i ka naphthalene i hoʻomaʻemaʻe ʻia i loko o ka ipu sulfonation a me ka wela (hoʻoheheʻe) i 140°C.Hoʻohui i 1.085 manawa (molar ratio) concentrated sulfuric acid i loko o 20min, hoʻonui i ka mahana, a mālama iā ia ma 160～164℃ no 2.5h.Hoʻopau ka hopena i ka hiki ʻana o ka 2-naphthalenesulfonic acid i ka 66% a ʻoi aku paha a ʻo ka nui o ka acidity he 25%-27%.Hoʻohāhā ʻia ka sulfonate i loko o kahi ipu hao ma 140~150 ℃ no 1h.A laila, i loko o ka ipu hao, e hoʻokaʻawale me ka sodium bisulfite solution ma 80 ~ 90 ℃ a hiki i ka ʻulaʻula ʻole o ka pepa hōʻike ʻulaʻula o Congo.E hoʻohana i ka mahu a me ka ea e hoʻokuke aku i ke kinoea SO2, maʻalili a hiki i 30-40°C a laila kānana hoʻoheheʻe, holoi me 10% wai paʻakai, a laila kānana hoʻoheheʻe e loaʻa ka sodium 2-naphthalenesulfonate.E kau i ka sodium hydroxide i loko o kahi ipu hoʻoheheʻe alkali, wela (melt) i 290 ° C, a hoʻohui i ka sodium 2-naphthalenesulfonate ma kahi o 3 mau hola a hiki i ka 5% a hiki i ka 6%.Ma hope o kēlā, mālama ʻia ma 320-330 ° C no 1 hola.Hoʻoheheʻe ʻia ka hoʻoheheʻe alkali i ka wai a hala i ka SO2 ma 70 ~ 80 ℃ a hiki i ka phenolphthalein ke kala ʻole.E hoʻohui i ka wai e hoʻolapalapa a holoi, wehe i ka sodium sulfite, a laila hoʻomaloʻo a hoʻoheheʻe ʻia ma lalo o ke kaomi hoʻemi e loaʻa ai ka huahana i hoʻopau ʻia.ʻO ka huina o ka hua he 73% a 74%.Hoʻohana ke ʻano 2-isopropylnaphthalene i ka naphthalene a me ka propylene ma ke ʻano he kumu waiwai no ka hana ʻana i ka 2-naphthol aʻo ka acetone huahana.
