ʻAno hana:
1. Hana ʻia ia mai ka naphthalene ma o ka sulfonation a me ka alkali fusion. ʻO ke ʻano hana sulfonated alkali fusion kahi ʻano hana i hoʻohana nui ʻia ma ka home a ma waho, akā he palaho koʻikoʻi, kumukūʻai kiʻekiʻe, a me ka hoʻohana ʻana i ka oxygen olaola kiʻekiʻe i loko o ka wai hoʻoneoneo. Hoʻohana ke ʻano 2-isopropylnaphthalene i hoʻomohala ʻia e ka American Cyanamide Company i ka naphthalene a me ka propylene ma ke ʻano he mea maka e hana ai i ka 2-naphthol ma ke ʻano he huahana ʻaoʻao o ka acetone. Ua like kēia ʻano hana me ka hana ʻana o ka phenol e ke ʻano cumene. Ka nui o ka hoʻohana ʻana i nā mea maka: naphthalene i hoʻomaʻemaʻe ʻia 1170kg/t, sulfuric acid 1080kg/t, solid caustic soda 700kg/t.

2.1) Ke ʻano hoʻoheheʻe alkali sulfonate. E kau i ka naphthalene i hoʻomaʻemaʻe ʻia i loko o ka ipu sulfonation a hoʻomehana (hoʻoheheʻe) i 140°C. E hoʻohui i 1.085 mau manawa (molar ratio) i ka waikawa sulfuric i hoʻopaʻa ʻia i loko o 20 mau minuke, e hoʻonui i ka mahana, a mālama iā ia ma 160-164°C no 2.5 mau hola. Pau ka hopena ke hiki ka nui o ka 2-naphthalenesulfonic acid i 66% a ʻoi aku paha a ʻo ka huina acidity he 25%-27%. Hoʻoheheʻe ʻia ka sulfonate i loko o kahi ipu hydrolysis ma 140-150℃ no 1h. A laila i loko o kahi ipu neutralization, neutralize me ka sodium hydrogen nitrite solution ma 80-90°C a hiki i ka wā e ʻole ai e polū ka pepa hoʻāʻo ʻulaʻula Congo. E hoʻohana i ka mahu a me ka ea e hoʻokuke aku i ke kinoea SO2, e hoʻomaʻalili i 30-40°C a laila kānana omo, holoi me 10% wai paʻakai, a laila kānana omo e loaʻa ai ka sodium 2-naphthalenesulfonate. E kau i ka sodium hydroxide i loko o kahi ipu hoʻoheheʻe alkali, e hoʻomehana (hoʻoheheʻe) i 290°C, a hoʻohui i ka sodium 2-naphthalenesulfonate ma kahi o 3 mau hola a hiki i ka nui o ka alkali manuahi he 5%-6%. Ma hope iho, ua mālama ʻia ma 320-330°C no 1 hola. Hoʻoheheʻe ʻia ka alkali i hoʻoheheʻe ʻia i loko o ka wai a hoʻokuʻu ʻia ka SO2 ma 70-80°C a hiki i ka wā ʻaʻohe kala o ka phenolphthalein. E hoʻohui i ka wai e hoʻolapalapa a holoi, e wehe i ka sodium sulfite, a laila e hoʻomaloʻo a hoʻoheheʻe ma lalo o ke kaomi i hoʻemi ʻia e loaʻa ai ka huahana i hoʻopau ʻia. ʻO ka huina o ka hua he 73%-74%.
2) Ke ʻano hana 2-isopropylnaphthalene. ʻO Chemicalbook, kahi e hoʻohana ai i ka naphthalene a me ka propylene ma ke ʻano he mea maka, hana hou i ka 2-naphthol i ka manawa like me ka huahana ʻaoʻao o ka acetone.

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

4. Ke ʻano hoʻoheheʻe alkali sulfonation E hoʻokomo i ka naphthalene i hoʻomaʻemaʻe ʻia i loko o kahi ipu sulfonation a hoʻomehana (hoʻoheheʻe) i 140°C. E hoʻohui i 1.085 mau manawa (lakio molar) i hoʻopaʻa ʻia ka waikawa sulfuric i loko o 20min, e hoʻonui i ka mahana, a mālama iā ia ma 160～164℃ no 2.5h. Pau ka hopena ke hiki ka nui o ka 2-naphthalenesulfonic acid i 66% a ʻoi aku paha a ʻo ka huina acidity he 25%-27%. Hoʻoheheʻe ʻia ka sulfonate i loko o kahi ipu hydrolysis ma 140～150℃ no 1h. A laila i loko o kahi ipu neutralization, neutralize me ka sodium bisulfite solution ma 80~90℃ a hiki i ka wā e ʻole ai e polū ka pepa hoʻāʻo ʻulaʻula Congo. E hoʻohana i ka mahu a me ka ea e hoʻokuke aku i ke kinoea SO2, e hoʻomaʻalili i 30-40°C a laila kānana omo, holoi me 10% wai paʻakai, a laila kānana omo e loaʻa ai ka sodium 2-naphthalenesulfonate. E kau i ka sodium hydroxide i loko o kahi ipu hoʻoheheʻe alkali, e hoʻomehana (hoʻoheheʻe) i 290°C, a hoʻohui i ka sodium 2-naphthalenesulfonate ma kahi o 3 mau hola a hiki i ka nui o ka alkali manuahi he 5% a 6%. Ma hope o kēlā, ua mālama ʻia ma 320-330°C no 1 hola. Hoʻoheheʻe ʻia ka alkali hoʻoheheʻe i loko o ka wai a hoʻokuʻu ʻia ʻo SO2 ma 70~80℃ a hiki i ka wā ʻaʻohe kala o ka phenolphthalein. E hoʻohui i ka wai e hoʻolapalapa a holoi, e wehe i ka sodium sulfite, a laila e hoʻomaloʻo a hoʻoheheʻe ma lalo o ke kaomi i hoʻemi ʻia e loaʻa ai ka huahana i hoʻopau ʻia. ʻO ka huina hua he 73% a 74%. Hoʻohana ke ʻano 2-isopropylnaphthalene i ka naphthalene a me ka propylene ma ke ʻano he mea maka e hana ai i ka 2-naphthol ʻoiai ʻo ka huahana acetone.
