Indlela yokukhiqiza:
1. Yenziwe nge-naphthalene ngokusebenzisa i-sulfonation kanye ne-alkali fusion.Indlela yokuhlanganisa i-alkali e-sulfonated iyindlela yokukhiqiza esetshenziswa kakhulu ekhaya naphesheya, kodwa inokugqwala okukhulu, izindleko eziphezulu, kanye nokusetshenziswa okuphezulu komoyampilo webhayoloji emanzini angcolile.Indlela ye-2-isopropylnaphthalene eyakhiwe yiNkampani yaseMelika ye-Cyanamide isebenzisa i-naphthalene ne-propylene njengezinto ezingavuthiwe ukukhiqiza i-2-naphthol njengomkhiqizo we-acetone.Le ndlela ifana nokukhiqizwa kwe-phenol ngendlela ye-cumene.Isilinganiso sokusetshenziswa kwempahla eluhlaza: i-naphthalene ecwengiwe 1170kg/t, i-sulfuric acid 1080kg/t, isoda eqinile ye-caustic 700kg/t.

2.1) Indlela yokuncibilikisa i-alkali ene-sulfonated.Faka i-naphthalene ecwengiwe ebhodweni le-sulfonation bese ushisa (ncibilikisa) ku-140 ° C.Engeza izikhathi ezingu-1.085 (isilinganiso se-molar) i-sulfuric acid egxilile ngaphakathi kwemizuzu engu-20, wandise izinga lokushisa, futhi ugcine ku-160-164 ° C amahora angu-2.5.Ukusabela kugcina lapho okuqukethwe kwe-2-naphthalenesulfonic acid kufinyelela ku-66% noma ngaphezulu futhi i-acidity ephelele ingu-25% -27%.I-sulfonate i-hydrolyzed ebhodweni le-hydrolysis ku-140-150 ℃ ihora elingu-1.Bese ebhodweni lokungathathi hlangothi, nciphisa ngesisombululo se-sodium hydrogen nitrite ku-80-90°C kuze kube yilapho iphepha lokuhlola elibomvu lase-Congo lingaphenduki libe luhlaza okwesibhakabhaka.Sebenzisa isitimu nomoya ukuxosha igesi ye-SO2, uphole ufike ku-30-40°C bese ususa isihlungi, ugeze ngamanzi anosawoti angu-10%, bese ukuhlunga ukuze uthole i-sodium 2-naphthalenesulfonate.Faka i-sodium hydroxide ebhodweni elincibilikisa i-alkali, shisa (ncibilikisa) kuye ku-290°C, bese wengeza i-sodium 2-naphthalenesulfonate cishe emahoreni angu-3 kuze kube yilapho okuqukethwe kwe-alkali yamahhala kungu-5% -6%.Ngemuva kwalokho, igcinwa ku-320-330 ° C ihora elingu-1.Ukuncibilika kwe-alkali kuhlanjululwa emanzini futhi kudlule i-SO2 ku-70-80°C kuze kube yilapho i-phenolphthalein ingenambala.Engeza amanzi ukuze ubilise futhi ugeze, susa i-sodium sulfite, bese ukhipha amanzi bese uphonsa ngaphansi kwengcindezi encishisiwe ukuze uthole umkhiqizo ophelile.Isamba sesivuno singama-73% -74%.
2) 2-isopropylnaphthalene indlela.I-Chemicalbook, esebenzisa i-naphthalene ne-propylene njengezinto zokusetshenziswa, ikhiqiza kabusha i-2-naphthol ngesikhathi esifanayo njengomkhiqizo we-acetone.

3. Indlela yokulungisa iwukwengeza i-sulfuric acid ku-naphthalene encibilikisiwe ku-140°C, yenza i-sulfonation ku-162～164°C, i-hydrolyze i-sulfonate, ikhiphe i-naphthalene yamahhala, bese isabela nge-sodium sulfite ukukhiqiza usawoti we-sodium o-2-naphthalenesulfonic acid. .Usawoti oqinile we-sodium kanye ne-sodium hydroxide ku-alkali-encibilika ku-285-320 ° C, bese igcinwa ku-320-330 ° C ihora elingu-1.Ukuncibilika kwe-alkali kuyahlanjululwa bese kudluliswa ku-sulphur dioxide ukuze kufakwe i-asidi ukuze kutholwe umkhiqizo ongahluziwe, ogezwayo futhi uphelelwe amanzi bese ugaywa ukuze uthole umkhiqizo.

4. Indlela yokuncibilika kwe-alkali ye-sulfonation Faka i-naphthalene ecolisisiwe ebhodweni le-sulfonation bese ushisa (ncibilikisa) kuye ku-140°C.Engeza izikhathi ezingu-1.085 (isilinganiso se-molar) i-sulfuric acid egxilile phakathi kuka-20min, khulisa izinga lokushisa, futhi uyigcine ku-160～164℃ amahora angu-2.5.Ukusabela kugcina lapho okuqukethwe kwe-2-naphthalenesulfonic acid kufinyelela ku-66% noma ngaphezulu futhi i-acidity ephelele ingu-25% -27%.I-sulfonate i-hydrolyzed ebhodweni le-hydrolysis ku-140～150℃ ihora elingu-1.Bese-ke ebhodweni lokungathathi hlangothi, nciphisa ngesisombululo se-sodium bisulfite ku-80~90℃ kuze kube yilapho iphepha lokuhlola elibomvu lase-Congo lingaphenduki libe luhlaza okwesibhakabhaka.Sebenzisa isitimu nomoya ukuxosha igesi ye-SO2, uphole ufike ku-30-40°C bese ususa isihlungi, ugeze ngamanzi anosawoti angu-10%, bese ukuhlunga ukuze uthole i-sodium 2-naphthalenesulfonate.Faka i-sodium hydroxide ebhodweni elincibilikayo eline-alkali, shisa (ncibilikisa) kuye ku-290°C, bese wengeza i-sodium 2-naphthalenesulfonate cishe emahoreni angu-3 kuze kube yilapho okuqukethwe kwe-alkali yamahhala kungu-5% kuya ku-6%.Ngemuva kwalokho, igcinwe ku-320-330 ° C ihora elingu-1.Ukuncibilika kwe-alkali kuhlanjululwa emanzini futhi kudlule i-SO2 ku-70~80℃ kuze kube i-phenolphthalein ingenambala.Engeza amanzi ukuze ubilise futhi ugeze, susa i-sodium sulfite, bese ukhipha amanzi bese ulahla ngaphansi kwengcindezi encishisiwe ukuze uthole umkhiqizo ophelile.Isamba sesivuno singama-73% kuya ku-74%.Indlela ye-2-isopropylnaphthalene isebenzisa i-naphthalene ne-propylene njengezinto zokusetshenziswa ukukhiqiza i-2-naphthol ngenkathi ngomkhiqizo we-acetone.
