Indlela yokukhiqiza:
1. Yenziwe nge-naphthalene ngokusebenzisa i-sulfonation kanye ne-alkali fusion. Indlela ye-sulfonated alkali fusion iyindlela yokukhiqiza esetshenziswa kabanzi ekhaya nakwamanye amazwe, kodwa inokugqwala okukhulu, izindleko eziphezulu, kanye nokusetshenziswa okuphezulu kwe-oxygen emanzini angcolile. Indlela ye-2-isopropylnaphthalene eyathuthukiswa yi-American Cyanamide Company isebenzisa i-naphthalene kanye ne-propylene njengezinto zokusetshenziswa ukukhiqiza i-2-naphthol njengomkhiqizo we-acetone. Le ndlela ifana nokukhiqizwa kwe-phenol ngendlela ye-cumene. Isilinganiso sokusetshenziswa kwezinto zokusetshenziswa: i-naphthalene ehlanjululwe engu-1170kg/t, i-sulfuric acid engu-1080kg/t, i-solid caustic soda engu-700kg/t.

2.1) Indlela yokuncibilikisa i-alkali e-sulfonated. Beka i-naphthalene ecolisisiwe ebhodweni le-sulfonation bese uyishisa (incibilike) ibe ngu-140°C. Engeza i-sulfuric acid egxilile izikhathi ezingu-1.085 (isilinganiso se-molar) zingakapheli imizuzu engama-20, wandise izinga lokushisa, bese uyigcina ku-160-164°C amahora angu-2.5. Ukusabela kuphela lapho okuqukethwe yi-2-naphthalenesulfonic acid kufinyelela ku-66% noma ngaphezulu kanti i-acidity iyonke ingu-25%-27%. I-sulfonate i-hydrolyzed ebhodweni le-hydrolysis ku-140-150℃ ihora eli-1. Bese ebhodweni le-neutralization, nciphisa ngesisombululo se-sodium hydrogen nitrite ku-80-90°C kuze kube yilapho iphepha lokuhlola elibomvu laseCongo lingaphenduki libe luhlaza okwesibhakabhaka. Sebenzisa umusi nomoya ukuze uxoshe igesi le-SO2, uphole ku-30-40°C bese ususa isihlungi, ugeze ngamanzi anosawoti angu-10%, bese ususa isihlungi ukuze uthole i-sodium 2-naphthalenesulfonate. Faka i-sodium hydroxide ebhodweni lokuncibilikisa i-alkali, ufudumale (uncibilike) ku-290°C, bese ufaka i-sodium 2-naphthalenesulfonate emahoreni angaba ma-3 kuze kube yilapho okuqukethwe kwe-alkali yamahhala kungama-5%-6%. Ngemva kwalokho, kwagcinwa ku-320-330°C ihora eli-1. Ukuncibilika kwe-alkali kuxutshwe emanzini bese kudluliswa i-SO2 ku-70-80°C kuze kube yilapho i-phenolphthalein ingenambala. Faka amanzi ukuze ubilise bese ugeza, susa i-sodium sulfite, bese ukhipha amanzi bese uhlanza ngaphansi kwengcindezi encishisiwe ukuze uthole umkhiqizo oqediwe. Isivuno esiphelele singama-73%-74%.
2) Indlela ye-2-isopropylnaphthalene. I-Chemicalbook, esebenzisa i-naphthalene ne-propylene njengezinto zokusetshenziswa, ikhiqiza i-2-naphthol ngesikhathi esifanayo nomkhiqizo ongezansi we-acetone.

3. Indlela yokulungiselela ukufaka i-sulfuric acid ku-naphthalene encibilikisiwe ku-140°C, ukwenza i-sulfonation ku-162~164°C, i-hydrolyze i-sulfonate, ikhiphe i-naphthalene yamahhala, bese isabela ne-sodium sulfite ukukhiqiza usawoti we-sodium we-2-naphthalenesulfonic acid. Usawoti we-sodium oqinile kanye ne-sodium hydroxide kuncibilikiswa ku-285-320°C, bese kugcinwa ku-320-330°C ihora eli-1. Ukuncibilika kwe-alkali kuyancibilikiswa bese kudluliselwa ku-sulfur dioxide ukuze kutholakale i-acid ukuze kutholakale umkhiqizo ongahluziwe, ogezwayo bese ukhishwa amanzi bese uncibilikiswa ukuze kutholakale umkhiqizo.

4. Indlela yokuncibilikisa i-alkali ye-sulfonation Faka i-naphthalene ecolisisiwe ebhodweni le-sulfonation bese uyishisa (incibilike) ibe ngu-140°C. Engeza i-sulfuric acid egxilile izikhathi ezingu-1.085 (isilinganiso se-molar) zingakapheli imizuzu engama-20, wandise izinga lokushisa, bese uyigcina ku-160～164℃ amahora angu-2.5. Ukusabela kuphela lapho okuqukethwe yi-2-naphthalenesulfonic acid kufinyelela ku-66% noma ngaphezulu kanti i-acidity iyonke ingu-25%-27%. I-sulfonate i-hydrolyzed ebhodweni le-hydrolysis ku-140～150℃ ihora eli-1. Bese ebhodweni le-neutralization, nciphisa ngesisombululo se-sodium bisulfite ku-80~90℃ kuze kube yilapho iphepha lokuhlola elibomvu laseCongo lingaphenduki libe luhlaza okwesibhakabhaka. Sebenzisa umusi nomoya ukuze uxoshe igesi ye-SO2, uphole ku-30-40°C bese uhlanza isihlungi sokudonsa, ugeze ngamanzi anosawoti angu-10%, bese uhlanza isihlungi sokudonsa ukuze uthole i-sodium 2-naphthalenesulfonate. Faka i-sodium hydroxide ebhodweni lokuncibilikisa i-alkali, ufudumale (uncibilike) ku-290°C, bese ufaka i-sodium 2-naphthalenesulfonate cishe emahoreni ama-3 kuze kube yilapho okuqukethwe kwe-alkali yamahhala kungama-5% kuya ku-6%. Ngemva kwalokho, kwagcinwa ku-320-330°C ihora eli-1. Ukuncibilika kwe-alkali kuxutshwe emanzini bese kudluliswa i-SO2 ku-70~80℃ kuze kube yilapho i-phenolphthalein ingenambala. Faka amanzi ukuze ubilise bese ugeza, ususe i-sodium sulfite, bese ukhipha amanzi bese uhlanza ngaphansi kwengcindezi encishisiwe ukuze uthole umkhiqizo oqediwe. Isivuno esiphelele singama-73% kuya ku-74%. Indlela ye-2-isopropylnaphthalene isebenzisa i-naphthalene ne-propylene njengezinto zokusetshenziswa ukukhiqiza i-2-naphthol ngenkathi umkhiqizo olandelanayo ukhipha i-acetone.
