Tikanga whakaputa:
1. He mea hanga mai i te naphthalene mā te sulfonation me te alkali fusion. Ko te tikanga sulfonated alkali fusion he tikanga whakaputa e whakamahia whānuitia ana i te kāinga me tāwāhi, engari he nui te waikura, he nui te utu, ā, he nui te whakamahinga hāora koiora i roto i te wai para. Ko te tikanga 2-isopropylnaphthalene i whakawhanakehia e te American Cyanamide Company e whakamahi ana i te naphthalene me te propylene hei rauemi mata hei whakaputa i te 2-naphthol hei hua taha o te acetone. He rite tēnei tikanga ki te whakaputanga o te phenol mā te tikanga cumene. Te rahinga kai rauemi mata: naphthalene kua parakore 1170kg/t, waikawa whanariki 1080kg/t, houra caustic totoka 700kg/t.

2.1) Tikanga rewa kawakawa kua whakapūkarahia. Whakanohoia te naphthalene kua whakapaia ki roto i te kohua whakapūkara, ka whakamahana (rewa) ki te 140°C. Tāpirihia he 1.085 ngā wā (ōwehenga molar) o te waikawa whanariki kukū i roto i te 20 meneti, whakanuia te pāmahana, ka pupuri i te 160-164°C mō te 2.5 hāora. Ka mutu te tauhohenga ina tae te ihirangi o te waikawa 2-naphthalenesulfonic ki te 66% neke atu rānei, ā, ko te waikawa katoa he 25%-27%. Ka whakapūkarahia te sulfonate i roto i te kohua whakapūkara i te 140-150℃ mō te 1 hāora. Kātahi ka whakapūkarahia ki roto i te kohua whakakorekore ki te otinga hauwai konutai nitrite i te 80-90°C kia kore ra ano e kikorangi te pepa whakamātautau whero o Congo. Whakamahia te mamaoa me te hau hei peia atu te hau SO2, whakamatao ki te 30-40°C, kātahi ka tātarihia, horoia ki te 10% wai tote, kātahi ka tātarihia kia whiwhi ai i te konutai 2-naphthalenesulfonate. Whakatakotoria te hauwai konutai ki roto i te kohua rewa kawakore, whakamahanatia (rewa) ki te 290°C, ka tāpirihia te konutai 2-naphthalenesulfonate i roto i te 3 hāora tae noa ki te 5%-6% te nui o te kawakore kore utu. Muri iho, ka puritia ki te 320-330°C mō te 1 hāora. Ka whakaranua te rewa kawakore ki te wai, ka tukuna te SO2 ki te 70-80°C tae noa ki te kore tae o te phenolphthalein. Tāpirihia te wai ki te kohua, ka horoia, tangohia te konutai sulfite, kātahi ka whakamaroke, ka whakatōtō i raro i te pēhanga iti kia puta ai te hua kua oti. Ko te hua katoa he 73%-74%.
2) Tikanga 2-isopropylnaphthalene. Ko Chemicalbook, e whakamahi ana i te naphthalene me te propylene hei rauemi mata, ka whakaputa anō i te 2-naphthol i te wā kotahi me te hua taha o te acetone.

3. Ko te tikanga whakarite ko te tāpiri i te waikawa whanariki ki te naphthalene rewa i te 140°C, te mahi i te sulfonation i te 162～164°C, te hydrolyze i te sulfonate, te pupuhi i te naphthalene kore utu, ka tauhohe ki te konutai sulfite hei whakaputa i te tote konutai waikawa 2-naphthalenesulfonic. Ka rewahia te tote konutai totoka me te konutai hauwai ki te kawakawa i te 285-320°C, kātahi ka puritia ki te 320-330°C mō te 1 hāora. Ka waimeha te rewa kawakawa ka tukuna ki roto i te hauhā whanariki hei whakakawa kia puta he hua mata, ka horoia, ka whakamaroketia, kātahi ka whakapūkara kia puta ai te hua.

4. Tikanga rewa kawakawa whakapūkara Tāpirihia te naphthalene kua whakapaia ki roto i te kohua whakapūkara ka whakamahana (rewa) ki te 140°C. Tāpirihia he 1.085 ngā wā (ōwehenga molar) o te waikawa whanariki kukū i roto i te 20 meneti, whakanuia te pāmahana, ka pupuri i te 160～164℃ mō te 2.5 hāora. Ka mutu te tauhohenga ina tae te ihirangi o te waikawa 2-naphthalenesulfonic ki te 66% neke atu rānei, ā, ko te waikawa katoa he 25%-27%. Ka whakapūkarahia te sulfonate i roto i te kohua whakapūkara i te 140～150℃ mō te 1 hāora. Kātahi ka whakapūkarahia ki roto i te kohua whakakorekore ki te otinga konutai bisulfite i te 80~90℃ kia kore ra ano e kikorangi te pepa whakamātautau whero o Congo. Whakamahia te mamaoa me te hau hei peia atu te hau SO2, whakamatao ki te 30-40°C, kātahi ka tātarihia, horoia ki te 10% wai tote, kātahi ka tātarihia kia whiwhi ai i te konutai 2-naphthalenesulfonate. Whakanohoia te hauwai konutai ki roto i te kohua rewa kawakore, whakamahanahia (rewa) ki te 290°C, ka tāpirihia te konutai 2-naphthalenesulfonate i roto i te 3 hāora tae noa ki te 5% ki te 6% te nui o te kawakore kore utu. Whai muri i tēnā, ka puritia ki te 320-330°C mō te 1 hāora. Ka whakaranua te rewa kawakore ki te wai ka tukuna te SO2 ki te 70~80℃ tae noa ki te kore tae o te phenolphthalein. Tāpirihia te wai ki te koropupū ka horoia, tangohia te konutai sulfite, kātahi ka whakamaroke ka whakahoro i raro i te pēhanga iti kia whiwhi ai i te hua kua oti. Ko te hua katoa he 73% ki te 74%. Ka whakamahia e te tikanga 2-isopropylnaphthalene te naphthalene me te propylene hei rauemi mata hei whakaputa i te 2-naphthol me te acetone hei hua taha.
