Tikanga whakaputa:
1. He mea hanga mai i te naphthalene na roto i te sulfonation me te whakakotahitanga alkali.Ko te tikanga whakangao alkali sulfonated he tikanga whakaputa i te kainga me nga whenua o waho, engari he nui te waikura, te utu nui, me te nui o te kohi 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-a-acetone.He rite tenei tikanga ki te hanga phenol ma te tikanga cumene.Te motunga kai maata: naphthalene parakore 1170kg/t, waikawa pungatara 1080kg/t, houra toka 700kg/t.

2.1) Tikanga whakakorewa kawakore whakawhaariki.Whakanohoia te naphthalene kua oti te para ki roto i te kohua sulfonation ka whakamahana (whakarewa) ki te 140°C.Tāpirihia kia 1.085 nga wa (molar ōwehenga) waikawa pungatara i roto i te 20 meneti, whakanuia te pāmahana, ka pupuri i te 160-164°C mo te 2.5 haora.Ka mutu te tauhohenga ina tae te ihirangi o te waikawa 2-naphthalenesulfonic ki te 66% neke atu ranei, ka 25%-27% te katoa o te waikawa.Ka whakamaua te sulfonate i roto i te kohua hauwai i te 140-150 ℃ mo te 1h.Na i roto i te kohua whakakore, whakakorehia ki te wairewa konutai hauwai nitrite i te 80-90°C kia kore ra ano te pepa whakamatautau whero o Congo e huri kikorangi.Whakamahia te mamaoa me te hau ki te pana atu i te hau SO2, whakamatao ki te 30-40°C katahi ka tātari momi, horoi ki te 10% wai tote, katahi ka tātari momi kia whiwhi konutai 2-naphthalenesulfonate.Whakanohoia te konutai waiwai ki roto i te kohua whakarewa kawakore, whakamahana (whakarewa) ki te 290°C, ka tapirihia te konutai 2-naphthalenesulfonate i roto i te 3 haora tae noa ki te 5%-6%.Muri iho, ka noho ki te 320-330°C mo te 1 haora.Ka waimeha te whakarewa alkali ki te wai ka tukuna te SO2 i te 70-80°C kia kore te tae o te phenolphthalein.Tāpirihia he wai ki te whewhe ka horoi, ka tango i te konutai sulfite, ka whakamakuku ka whakamakuku i raro i te pehanga iti kia whiwhi ai i te hua kua oti.Ko te hua katoa ko te 73%-74%.
2) tikanga 2-isopropylnaphthalene.Pukapuka matū, e whakamahi ana i te naphthalene me te propylene hei rauemi mata, ka whakaputa ano i te 2-naphthol i te wa ano hei hua-a-acetone.

3. Ko te tikanga whakarite ko te whakauru i te waikawa pungatara ki te naphthalene whakarewa i te 140°C, ka mahia te whakangao i te 162~164°C, te whakamaarama i te sulfonate, te pupuhi i te naphthalene kore utu, me te tauhohe ki te konutai sulfite ki te whakaputa 2-naphthalenesulfonic acid konutai tote .Ko te tote konutai totoka me te konutai konutai he kawakore-whakarewa i te 285-320°C, ka mau ki te 320-330°C mo te 1 haora.Ka waimeha te rewa kawakawa ka tukuna ki roto i te whanariki hauhā mo te waikawa kia puta mai he hua maru, ka horoia, ka whakamakukuhia, katahi ka maturu kia whiwhi ai te hua.

4. Te tikanga whakakorewatanga kawakawa whakangao sulfonation Kuhua te naphthalene parakore ki roto i te kohua sulfonation ka whakamahana (whakarewa) ki te 140°C.Tāpirihia kia 1.085 wa (te ōwehenga molar) te waikawa pungatara i roto i te 20 meneti, whakanuia te pāmahana, ka pupuri i te 160~164℃ mo te 2.5h.Ka mutu te tauhohenga ina tae te ihirangi o te waikawa 2-naphthalenesulfonic ki te 66% neke atu ranei, ka 25%-27% te katoa o te waikawa.Ka whakamarohia te sulfonate ki roto i te kohua hauwai i te 140~150 ℃ mo te 1 haora.Na i roto i te kohua whakakore, whakakorehia ki te otinga konutai bisulfite i te 80 ~ 90 ℃ kia kore ra ano te pepa whakamatautau whero o Congo e huri kikorangi.Whakamahia te mamaoa me te hau ki te pana atu i te hau SO2, whakamatao ki te 30-40°C katahi ka tātari momi, horoi ki te 10% wai tote, katahi ka tātari momi kia whiwhi konutai 2-naphthalenesulfonate.Whakanohoia te konutai waiwai ki roto i te kohua whakarewa kawakore, whakamahana (whakarewa) ki te 290°C, ka tapirihia te konutai 2-naphthalenesulfonate i roto i te 3 haora tae noa ki te 5% ki te 6%.I muri i tera, ka mau ki te 320-330°C mo te 1 haora.Ka waimeha te rewa kawa ki te wai ka paahitia te SO2 i te 70~80 ℃ kia kore te tae o te phenolphthalein.Tāpirihia he wai ki te whewhe ka horoi, ka tango i te konutai sulfite, ka whakamakuku ka whakamakuku i raro i te pehanga iti kia whiwhi ai i te hua kua oti.Ko te katoa o nga hua ko te 73% ki te 74%.Ko te tikanga 2-isopropylnaphthalene e whakamahi ana i te naphthalene me te propylene hei rauemi mata hei whakaputa i te 2-naphthol me te acetone-hua.
