Njira yopangira:
1. Amapangidwa kuchokera ku naphthalene kupyolera mu sulfonani ndi alkali fusion.Njira ya sulfonated alkali fusion ndi njira yomwe imagwiritsidwa ntchito kwambiri kunyumba ndi kunja, koma imakhala ndi dzimbiri, kukwera mtengo, komanso kugwiritsa ntchito mpweya wambiri wachilengedwe m'madzi oyipa.Njira ya 2-isopropylnaphthalene yopangidwa ndi American Cyanamide Company imagwiritsa ntchito naphthalene ndi propylene ngati zipangizo zopangira 2-naphthol monga mankhwala a acetone.Njirayi ndi yofanana ndi kupanga phenol ndi njira ya cumene.Zopangira zopangira zopangira: naphthalene woyengedwa 1170kg/t, asidi sulfuric 1080kg/t, koloko olimba 700kg/t.

2.1) Njira yosungunuka ya alkali ya sulfonated.Ikani naphthalene yoyengedwa mumphika wa sulfonani ndikutenthetsa (sungunulani) mpaka 140 ° C.Onjezerani nthawi za 1.085 (chiŵerengero cha molar) chokhazikika cha sulfuric acid mkati mwa mphindi 20, onjezerani kutentha, ndikusunga pa 160-164 ° C kwa maola 2.5.Zimene umatha pamene zili 2-naphthalenesulfonic asidi ukufika 66% kapena kuposa ndipo okwana acidity ndi 25% -27%.The sulfonate ndi hydrolyzed mu hydrolysis mphika pa 140-150 ℃ kwa 1h.Kenako mumphika wosalowererapo, chepetsani ndi sodium hydrogen nitrite solution pa 80-90 ° C mpaka pepala lofiira la Congo lisatembenuke buluu.Ntchito nthunzi ndi mpweya kuthamangitsa mpweya SO2, ozizira 30-40 ° C ndiyeno suction fyuluta, kusamba ndi 10% madzi amchere, ndiyeno suction fyuluta kupeza sodium 2-naphthalenesulfonate.Ikani sodium hydroxide mumphika wosungunuka wa alkali, kutentha (kusungunula) mpaka 290 ° C, ndipo onjezerani sodium 2-naphthalenesulfonate pafupifupi maola atatu mpaka mchere waulere uli 5% -6%.Pambuyo pake, imasungidwa pa 320-330 ° C kwa ola limodzi.Kusungunuka kwa alkali kumachepetsedwa m'madzi ndikudutsa SO2 pa 70-80 ° C mpaka phenolphthalein ilibe mtundu.Onjezani madzi kuwira ndi kusamba, chotsani sodium sulfite, ndiyeno tsitsani madzi ndi distill pansi pa kupanikizika kochepa kuti mupeze mankhwala omalizidwa.Zokolola zonse ndi 73% -74%.
2) 2-isopropylnaphthalene njira.Chemicalbook, yomwe imagwiritsa ntchito naphthalene ndi propylene ngati zopangira, imatulutsa 2-naphthol nthawi yomweyo ngati yopangidwa ndi acetone.

3. Njira yokonzekera ndikuwonjezera sulfuric acid ku naphthalene yosungunuka pa 140 ° C, kuchita sulfonation pa 162 ~ 164 ° C, hydrolyze sulfonate, kuwombera naphthalene yaulere, ndikuchitapo ndi sodium sulfite kupanga 2-naphthalenesulfonic acid sodium mchere. .Mchere wolimba wa sodium ndi sodium hydroxide zimasungunuka pa 285-320 ° C, kenako zimasungidwa pa 320-330 ° C kwa ola limodzi.Kusungunuka kwa alkali kumachepetsedwa ndikuperekedwa mu sulfure dioxide kuti acidity ipeze zinthu zopanda pake, zomwe zimatsukidwa ndi kuchotsedwa madzi m'thupi ndikusungunulidwa kuti mupeze mankhwalawo.

4. Njira yosungunula sulfonani alkali Ikani naphthalene woyengedwa mumphika wa sulfoni ndi kutentha (sungunulani) mpaka 140°C.Onjezani nthawi 1.085 (chiwerengero cha molar) chokhazikika cha sulfuric acid mkati mwa 20min, onjezerani kutentha, ndikusunga pa 160～164℃ kwa 2.5h.Zimene umatha pamene zili 2-naphthalenesulfonic asidi ukufika 66% kapena kuposa ndipo okwana acidity ndi 25% -27%.Sulfonate imapangidwa ndi hydrolyzed mumphika wa hydrolysis pa 140 ~ 150 ℃ kwa 1h.Kenako mumphika wosalowererapo, chepetsani ndi sodium bisulfite solution pa 80 ~ 90 ℃ mpaka pepala lofiira la Congo lisatembenuke buluu.Ntchito nthunzi ndi mpweya kuthamangitsa mpweya SO2, ozizira 30-40 ° C ndiyeno kuyamwa fyuluta, kusamba ndi 10% madzi amchere, ndiyeno suction fyuluta kupeza sodium 2-naphthalenesulfonate.Ikani sodium hydroxide mumphika wosungunuka wa alkali, kutentha (kusungunuka) mpaka 290 ° C, ndi kuwonjezera sodium 2-naphthalenesulfonate pafupifupi maola atatu mpaka mchere waulere utakhala 5% mpaka 6%.Pambuyo pake, imasungidwa pa 320-330 ° C kwa ola limodzi.Kusungunuka kwa alkali kumachepetsedwa m'madzi ndikudutsa SO2 pa 70 ~ 80 ℃ mpaka phenolphthalein ndi yopanda mtundu.Onjezani madzi kuwira ndi kutsuka, chotsani sodium sulfite, ndiyeno tsitsani madzi ndi distill pansi pa kupanikizika kochepa kuti mupeze mankhwala omalizidwa.Zokolola zonse ndi 73% mpaka 74%.Njira ya 2-isopropylnaphthalene imagwiritsa ntchito naphthalene ndi propylene ngati zipangizo zopangira 2-naphthol pamene ndi mankhwala acetone.
