2.1) Metotia o le fa'amalūlūina o le sulfonate alkali. Tu'u le naphthalene ua fa'amamāina i totonu o le ulo sulfonation ma fa'avevela (fa'amalūlūina) i le 140°C. Fa'aopopo le 1.085 taimi (molar ratio) o le sulfuric acid fa'aputu i totonu o le 20 minute, fa'ateleina le vevela, ma taofi i le 160-164°C mo le 2.5 itula. E muta le tali atu pe a o'o atu le aofa'i o le 2-naphthalenesulfonic acid i le 66% pe sili atu ma o le aofa'i o le acidity e 25%-27%. E fa'amalūlūina le sulfonate i totonu o se ulo hydrolysis i le 140-150℃ mo le 1 itula. Ona fa'amalūlūina lea i totonu o se ulo neutralization i le sodium hydrogen nitrite solution i le 80-90°C se'ia o'o ina le liua le pepa su'ega mumu o Congo i le lanumoana. Fa'aaoga le ausa ma le ea e tuli ese ai le kesi SO2, fa'amālūlū i le 30-40°C ona fa'amamā lea, fufulu i le 10% vai masima, ona fa'amamā lea e maua ai le sodium 2-naphthalenesulfonate. Tuu le sodium hydroxide i totonu o se ulo fa'afefiloi alkali, fa'avevela (fa'afefiloi) i le 290°C, ma fa'aopopo le sodium 2-naphthalenesulfonate i le tusa ma le 3 itula se'ia o'o ina 5%-6% le aofa'i o le alkali saoloto. A mae'a lea, ona taofia lea i le 320-330°C mo le 1 itula. O le alkali fa'afefiloi e fa'afefiloi i le vai ma fa'asolo le SO2 i le 70-80°C se'ia leai se lanu o le phenolphthalein. Fa'aopopo le vai e fa'apuna ma fufulu, aveese le sodium sulfite, ona fa'amago lea ma fa'amamago i lalo o le mamafa fa'aitiitia e maua ai le oloa mae'a. O le aofa'i atoa e maua mai ai e 73%-74%.
2) Metotia 2-isopropylnaphthalene. O le Chemicalbook, lea e faʻaaogaina ai le naphthalene ma le propylene o ni mea mata, e toe gaosia ai le 2-naphthol i le taimi lava e tasi e pei o se oloa e maua mai le acetone.

3. O le auala e saunia ai o le fa'aopoopoina lea o le sulfuric acid i le naphthalene ua liusuavai i le 140°C, fa'atino le sulfonation i le 162～164°C, fa'a-hydrolyze le sulfonate, fa'apuna ese le naphthalene saoloto, ma fa'afetaui ma le sodium sulfite e maua ai le 2-naphthalenesulfonic acid sodium salt. O le sodium salt malō ma le sodium hydroxide e fa'a-alkali i le 285-320°C, ona teuina lea i le 320-330°C mo le 1 itula. O le alkali melt e fa'a-dissolve ma tu'u i totonu o le sulfur dioxide mo le fa'a-acidification e maua ai se oloa mata, lea e fufuluina ma fa'amago ona fa'amamāina lea e maua ai le oloa.

4. Metotia o le fa'amalūlūina o le sulfonation alkali Tuu le naphthalene ua fa'amamaina i totonu o se ulo sulfonation ma fa'avevela (fa'amalūlūina) i le 140°C. Fa'aopopo le 1.085 taimi (molar ratio) o le sulfuric acid fa'aputu i totonu o le 20 minute, fa'ateleina le vevela, ma taofi i le 160～164℃ mo le 2.5 itula. E muta le tali atu pe a o'o atu le aofa'i o le 2-naphthalenesulfonic acid i le 66% pe sili atu ma o le aofa'i o le acidity e 25%-27%. E fa'amalūlūina le sulfonate i totonu o se ulo hydrolysis i le 140～150℃ mo le 1 itula. Ona fa'amalūlūina lea i totonu o se ulo neutralization i le sodium bisulfite solution i le 80~90℃ se'ia o'o ina le liua le pepa su'ega mumu Congo i le lanumoana. Fa'aaoga le ausa ma le ea e fa'ate'a ese ai le kesi SO2, fa'amālūlū i le 30-40°C ona fa'amamā lea, fufulu i le 10% vai masima, ona fa'amamā lea e maua ai le sodium 2-naphthalenesulfonate. Tuu le sodium hydroxide i totonu o se ulo fa'afefiloi alkali, fa'avevela (fa'afefiloi) i le 290°C, ma fa'aopopo le sodium 2-naphthalenesulfonate i le tusa ma le 3 itula se'ia o'o ina 5% i le 6% le aofa'i o le alkali saoloto. A mae'a lena, ona taofia lea i le 320-330°C mo le 1 itula. O le alkali fa'afefiloi e fa'afefiloi i le vai ma fa'asolo le SO2 i le 70~80℃ se'ia leai se lanu o le phenolphthalein. Fa'aopopo le vai e fa'apuna ma fufulu, aveese le sodium sulfite, ona fa'amago lea ma fa'amamago i lalo o le mamafa fa'aitiitia e maua ai le oloa mae'a. O le aofa'i atoa e 73% i le 74%. O le metotia 2-isopropylnaphthalene e fa'aogaina le naphthalene ma le propylene o ni mea mata e gaosia ai le 2-naphthol a'o le acetone e maua mai ai.
