Ọna iṣelọpọ:
1. O ṣe lati naphthalene nipasẹ sulfonation ati idapọ alkali. Ọna idapọ alkali sulfonated jẹ ọna iṣelọpọ ti a lo lọpọlọpọ ni ile ati ni okeere, ṣugbọn o ni ipata to ṣe pataki, idiyele giga, ati agbara atẹgun ti ibi giga ninu omi idọti. Ọna 2-isopropylnaphthalene ti o dagbasoke nipasẹ Ile-iṣẹ Cyanamide Amẹrika nlo naphthalene ati propylene bi awọn ohun elo aise lati ṣe 2-naphthol gẹgẹbi ọja nipasẹ-ọja ti acetone. Ọna yii jẹ iru si iṣelọpọ ti phenol nipasẹ ọna cumene. Ipin agbara ohun elo aise: naphthalene ti a ti tunṣe 1170kg/t, sulfuric acid 1080kg/t, soda caustic ti o lagbara 700kg/t.

2.1) Sulfonated alkali yo ọna. Gbe naphthalene ti a ti tunṣe sinu ikoko sulfonation ati ooru (yo) si 140°C. Ṣafikun awọn akoko 1.085 (ipin molar) sulfuric acid ti o ni idojukọ laarin iṣẹju 20, mu iwọn otutu pọ si, ki o jẹ ki o wa ni 160-164°C fun wakati 2.5. Idahun naa dopin nigbati akoonu ti 2-naphthalenesulfonic acid de 66% tabi diẹ sii ati pe apapọ acidity jẹ 25% -27%. Awọn sulfonate ti wa ni hydrolyzed ni a hydrolysis ikoko ni 140-150 ℃ fun 1h. Lẹhinna ninu ikoko didoju, yomi pẹlu iṣuu soda hydrogen nitrite ojutu ni 80-90 ° C titi ti iwe idanwo pupa Congo ko ni tan-bulu. Lo nya si ati afẹfẹ lati wakọ gaasi SO2, tutu si 30-40°C ati lẹhinna àlẹmọ afamora, wẹ pẹlu omi iyọ 10%, lẹhinna àlẹmọ afamora lati gba iṣuu soda 2-naphthalenesulfonate. Fi iṣuu soda hydroxide sinu ikoko alkali kan, ooru (yo) si 290 ° C, ki o si fi iṣuu soda 2-naphthalenesulfonate kun ni bii wakati 3 titi ti akoonu alkali ọfẹ yoo jẹ 5% -6%. Lẹhin eyi, o jẹ 320-330 ° C fun wakati kan. Alkali yo ti wa ni ti fomi po ninu omi ati ki o koja SO2 ni 70-80 ° C titi phenolphthalein ni awọ. Fi omi kun lati sise ati ki o wẹ, yọ iṣuu soda sulfite, lẹhinna gbẹ ati distill labẹ titẹ dinku lati gba ọja ti o pari. Apapọ ikore jẹ 73% -74%.
2) 2-isopropylnaphthalene ọna. Iwe kemikali, eyiti o nlo naphthalene ati propylene bi awọn ohun elo aise, tun ṣe 2-naphthol ni akoko kanna gẹgẹbi ọja-ọja ti acetone.

3. Ọna igbaradi ni lati fi sulfuric acid sinu didà naphthalene ni 140 ° C, ṣe sulfonation ni 162 ~ 164 ° C, hydrolyze sulfonate, fẹ pa naphthalene ọfẹ, ki o si fesi pẹlu sodium sulfite lati ṣe iyọ 2-naphthalenesulfonic acid sodium iyọ. . Iyọ iṣu soda ti o lagbara ati iṣuu soda hydroxide jẹ alkali-yo ni 285-320 ° C, ati lẹhinna tọju ni 320-330 ° C fun wakati kan. Awọn alkali yo ti wa ni ti fomi ati ki o kọja sinu imi-ọjọ oloro fun acidification lati gba a robi ọja, eyi ti o ti fo ati ki o dehydrated ati ki o si distilled lati gba awọn ọja.

4. Sulfonation alkali yo ọna Fi naphthalene refaini sinu kan sulfonation ikoko ati ooru (yo) to 140 ° C. Ṣafikun awọn akoko 1.085 (ipin molar) sulfuric acid ogidi laarin iṣẹju 20, mu iwọn otutu pọ si, ki o jẹ ki o wa ni 160～164℃ fun wakati 2.5. Idahun naa dopin nigbati akoonu ti 2-naphthalenesulfonic acid de 66% tabi diẹ sii ati pe apapọ acidity jẹ 25% -27%. Sulfonate jẹ hydrolyzed ninu ikoko hydrolysis ni 140 ~ 150 ℃ fun wakati kan. Lẹhinna ninu ikoko didoju, yomi pẹlu ojutu bisulfite iṣuu soda ni 80 ~ 90 ℃ titi ti iwe idanwo pupa Congo ko ni tan buluu. Lo nya si ati afẹfẹ lati wakọ gaasi SO2, tutu si 30-40°C ati lẹhinna àlẹmọ afamora, wẹ pẹlu omi iyọ 10%, lẹhinna àlẹmọ afamora lati gba iṣuu soda 2-naphthalenesulfonate. Fi iṣuu soda hydroxide sinu ikoko alkali kan, ooru (yo) si 290 ° C, ki o si fi iṣuu soda 2-naphthalenesulfonate kun ni bii wakati 3 titi ti akoonu alkali ọfẹ yoo jẹ 5% si 6%. Lẹhin eyi, o wa ni 320-330 ° C fun wakati kan. Alkali yo ti wa ni ti fomi po ninu omi ati ki o koja SO2 ni 70 ~ 80 ℃ titi phenolphthalein ni colorless. Fi omi kun lati sise ati ki o wẹ, yọ iṣuu soda sulfite, lẹhinna gbẹ ati distill labẹ titẹ dinku lati gba ọja ti o pari. Apapọ ikore jẹ 73% si 74%. Ọna 2-isopropylnaphthalene nlo naphthalene ati propylene gẹgẹbi awọn ohun elo aise lati ṣe agbejade 2-naphthol lakoko ti ọja-ọja acetone.
