Txoj kev tsim khoom:
1. Nws yog ua los ntawm naphthalene los ntawm sulfonation thiab alkali fusion. Txoj kev sulfonated alkali fusion yog ib txoj kev tsim khoom siv dav hauv tsev thiab txawv teb chaws, tab sis nws muaj kev xeb loj heev, tus nqi siab, thiab kev siv oxygen ntau hauv cov dej khib nyiab. Txoj kev 2-isopropylnaphthalene tsim los ntawm American Cyanamide Company siv naphthalene thiab propylene ua cov khoom siv raw los tsim 2-naphthol ua cov khoom seem ntawm acetone. Txoj kev no zoo ib yam li kev tsim cov phenol los ntawm txoj kev cumene. Cov khoom siv raw siv quota: refined naphthalene 1170kg / t, sulfuric acid 1080kg / t, khoom caustic soda 700kg / t.

2.1) Txoj kev yaj sulfonated alkali. Muab cov naphthalene uas tau ua kom huv si tso rau hauv lub lauj kaub sulfonation thiab ua kom sov (yaj) txog 140°C. Ntxiv 1.085 npaug (molar ratio) concentrated sulfuric acid hauv 20 feeb, nce qhov kub, thiab khaws cia rau ntawm 160-164°C rau 2.5 teev. Qhov kev ua haujlwm xaus thaum cov ntsiab lus ntawm 2-naphthalenesulfonic acid ncav cuag 66% lossis ntau dua thiab tag nrho cov acidity yog 25%-27%. Cov sulfonate raug hydrolyzed hauv lub lauj kaub hydrolysis ntawm 140-150 ℃ rau 1 teev. Tom qab ntawd hauv lub lauj kaub neutralization, neutralize nrog sodium hydrogen nitrite kua ntawm 80-90°C kom txog thaum daim ntawv xeem liab Congo tsis tig xiav. Siv cov pa thiab cua kom tsav cov pa SO2 tawm, txias rau 30-40°C thiab tom qab ntawd lim dej nqus, ntxuav nrog 10% dej ntsev, thiab tom qab ntawd lim dej nqus kom tau sodium 2-naphthalenesulfonate. Muab cov sodium hydroxide tso rau hauv lub lauj kaub alkali melting, cua sov (yaj) rau 290 ° C, thiab ntxiv sodium 2-naphthalenesulfonate li 3 teev kom txog thaum cov alkali dawb yog 5% -6%. Tom qab ntawd, nws tau khaws cia ntawm 320-330 ° C rau 1 teev. Alkali yaj yog diluted hauv dej thiab dhau SO2 ntawm 70-80 ° C kom txog thaum phenolphthalein tsis muaj xim. Ntxiv dej kom npau thiab ntxuav, tshem tawm sodium sulfite, thiab tom qab ntawd dehydrate thiab distill nyob rau hauv txo qhov siab kom tau txais cov khoom tiav. Tag nrho cov txiaj ntsig yog 73% -74%.
2) 2-isopropylnaphthalene txoj kev. Chemicalbook, uas siv naphthalene thiab propylene ua cov khoom siv raw, rov tsim 2-naphthol tib lub sijhawm ua cov khoom seem ntawm acetone.

3. Txoj kev npaj yog ntxiv sulfuric acid rau hauv naphthalene uas yaj ntawm 140°C, ua sulfonation ntawm 162 ～ 164°C, hydrolyze cov sulfonate, tshuab cov naphthalene dawb tawm, thiab teb nrog sodium sulfite los tsim 2-naphthalenesulfonic acid sodium ntsev. Cov ntsev sodium khov thiab sodium hydroxide yog alkali-yaj ntawm 285-320°C, thiab tom qab ntawd khaws cia ntawm 320-330°C rau 1 teev. Cov alkali yaj yog diluted thiab dhau mus rau hauv sulfur dioxide rau acidification kom tau txais cov khoom nyoos, uas yog ntxuav thiab qhuav thiab tom qab ntawd distilled kom tau txais cov khoom.

4. Txoj kev yaj sulfonation alkali Muab cov naphthalene uas tau ua kom zoo rau hauv lub lauj kaub sulfonation thiab ua kom sov (yaj) txog 140°C. Ntxiv 1.085 npaug (molar ratio) concentrated sulfuric acid hauv 20 feeb, nce qhov kub, thiab khaws cia ntawm 160 ~ 164 ℃ rau 2.5 teev. Qhov kev ua haujlwm xaus thaum cov ntsiab lus ntawm 2-naphthalenesulfonic acid ncav cuag 66% lossis ntau dua thiab tag nrho cov acidity yog 25% -27%. Cov sulfonate raug hydrolyzed hauv lub lauj kaub hydrolysis ntawm 140 ~ 150 ℃ rau 1 teev. Tom qab ntawd hauv lub lauj kaub neutralization, neutralize nrog sodium bisulfite kua ntawm 80 ~ 90 ℃ kom txog thaum daim ntawv xeem liab Congo tsis tig xiav. Siv cov pa thiab cua kom tsav cov roj SO2, txias rau 30-40°C thiab tom qab ntawd lim dej nqus, ntxuav nrog 10% dej ntsev, thiab tom qab ntawd lim dej nqus kom tau txais sodium 2-naphthalenesulfonate. Muab cov sodium hydroxide tso rau hauv lub lauj kaub alkali melting, cua sov (yaj) rau 290 ° C, thiab ntxiv sodium 2-naphthalenesulfonate li 3 teev kom txog thaum cov alkali dawb yog 5% txog 6%. Tom qab ntawd, nws tau khaws cia ntawm 320-330 ° C rau 1 teev. Alkali yaj yog diluted hauv dej thiab dhau SO2 ntawm 70 ~ 80 ℃ kom txog thaum phenolphthalein tsis muaj xim. Ntxiv dej kom npau thiab ntxuav, tshem tawm sodium sulfite, thiab tom qab ntawd dehydrate thiab distill nyob rau hauv txo qhov siab kom tau txais cov khoom tiav. Tag nrho cov txiaj ntsig yog 73% txog 74%. Txoj kev 2-isopropylnaphthalene siv naphthalene thiab propylene ua cov khoom siv raw los tsim 2-naphthol thaum by-product acetone.
