2-naphthol tshuaj muaj zog thiab ruaj khov:
Cov tshuaj toxicology zoo ib yam li phenol, thiab nws muaj zog corrosive. Nws yog heev irritating rau ntawm daim tawv nqaij. Nws yog yooj yim absorbed los ntawm daim tawv nqaij. Toxic rau cov ntshav ncig thiab lub raum. Tsis tas li ntawd, nws tuaj yeem ua rau pob txha puas. Txawm hais tias qhov koob tshuaj tuag tsis meej, muaj cov neeg tuag los ntawm kev siv sab nraud ntawm 3-4g. Cov cuab yeej tsim khoom yuav tsum tau muab khi thiab cov pov thawj pov thawj, thiab cov txaws ntawm daim tawv nqaij yuav tsum tau ntxuav kom huv si. Lub rooj cob qhia yuav tsum tau ua kom cua thiab cov khoom siv yuav tsum raug kaw. Cov neeg ua haujlwm yuav tsum hnav cov khoom tiv thaiv.
Nws yog combustible, thiab xim yuav darker tom qab ntev - lub sij hawm cia. Nws ruaj khov nyob rau hauv huab cua, tab sis xim yuav tsaus dua thaum raug tshav ntuj. Thaum tshav kub kub sublimation, nrog pungent phenol tsw
Muaj nyob rau hauv flue gas.
Cov tshuaj tiv thaiv ntawm aqueous tov thiab ferric chloride yog ntsuab.
Synthesis ntawm2-Napthol hmoov:
1. Nws yog npaj los ntawm naphthalene los ntawm sulfonation thiab alkali melting. Sulfonated alkali melting yog ib txoj kev siv ntau lawm hauv tsev thiab txawv teb chaws, tab sis nws muaj kev xeb loj, tus nqi siab thiab kev siv cov pa oxygen siab hauv cov dej khib nyiab. Cov txheej txheem 2-isopropyl naphthalene tsim los ntawm lub tuam txhab cyanamide ntawm Tebchaws Meskas siv naphthalene thiab propylene ua raw khoom los tsim 2-naphthol thiab acetone los ntawm cov khoom. Cov txheej txheem no zoo ib yam li cov txheej txheem tsim cov phenol nrog isopropyl benzene.
2. Thaum tshav kub kub thiab yaj refined naphthalene, ntxiv sulfuric acid, thiab tom qab ntawd kub rau sulfonation tshuaj tiv thaiv. Thaum cov ntsiab lus ntawm 2-naphthalenesulfonic acid ntau tshaj 66% thiab tag nrho cov acidity yog 25% mus rau 27%, cov tshuaj tiv thaiv ua tiav, hydrolyzed, thiab dawb naphthalene yog tshuab nrog chav. Sodium sulfate tov yog maj mam thiab sib npaug ntxiv rau cov tshuaj tiv thaiv nruab nrab kom txog thaum Congo liab daim ntawv xeem tsis tshwm xiav.
3. Cov roj sulfur dioxide tsim tawm hauv cov tshuaj tiv thaiv raug tshem tawm raws sijhawm los ntawm chav, thiab cov khoom nruab nrab yog txias thiab crystallized. Cov muaju uas tau los ntawm kev nqus pom yog ntxuav nrog 10% saline daws, qhuav, thiab tom qab ntawd ntxiv nrog molten 98% sodium hydroxide ntawm qhov kub ntawm 300-310 ° C. Cov sib tov yog nplawm thiab tuav ntawm 320-330 ° C kom alkalize sodium 2-naphthalenesulfonate rau sodium 2-naphthalenesulfonate.
4. Tom qab ntawd dilute cov alkali yaj nrog dej kub thiab qhia cov sulfur dioxide uas ua los ntawm cov tshuaj tiv thaiv neutralization. Cov tshuaj tiv thaiv acidification yog nqa tawm ntawm 70-80℃C kom txog thaum phenolphthalein tsis muaj xim.
5. Cov khoom siv acidified yog muab tso rau txheej txheej thiab tom qab ntawd rhuab mus rau boiling sab sauv kua. Tom qab sawv, txheej txheej dej raug tshem tawm. Cov crude 2-naphthol tau txais yog thawj zaug rhuab thiab lub cev qhuav dej, thiab tom qab ntawd distilled nyob rau hauv qis qis kom tau cov khoom ntshiab.
6. Tshem tawm 1-naphthol los ntawm 2-naphthol los ntawm extraction crystallization. Sib tov 2-naphthol nrog dej hauv ib qho kev faib ua feem thiab ua kom sov rau 95 ° C. Tom qab 2-naphthol yog yaj, do cov sib tov kom huv si thiab ceev kom txias kom txog li 85 ° C, txias cov khoom siv crystalline slurry rau chav tsev kub thiab lim nws. Los ntawm kev tsom xam purity, cov ntsiab lus ntawm 1-naphthol yog kab.
7. Npaj los ntawm 2-naphthalene sulfonic acid los ntawm alkali melting.
2-Naphthol (tshuaj formula C10H8O), tseem hu ua ethylnaphthol, - naphthol, 2-hydroxynaphthalene, thiab lwm yam, yog ib tug dawb mus rau liab phaj zoo li siv lead ua uas darkens nyob rau hauv cov xim thaum khaws cia nyob rau hauv huab cua ntev, sublimates thaum cua sov, thiab muaj ib tug pungent phenol. Nws cov tshuaj aqueous reacts ntsuab nrog ferric chloride thiab muaj ntau yam tseem ceeb siv, ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw.
