1. Toxicology waxay la mid tahay phenol, waana daxalka ka xoog badan. Si xoog leh u xanaaqa maqaarka. Si fudud ayaa loo nuugo maqaarka. Sun ku ah wareegga dhiigga iyo kelyaha. Intaa waxaa dheer, waxay keeni kartaa dhaawaca lafaha. Inkastoo aan la ogeyn inta ay le'eg tahay tirada dhimashada, waxaa jiray kiisas dhimasho ah oo ka yimid isticmaalka jirka ee 3 ilaa 4g. Qalabka wax-soo-saarka waa in la xidhaa oo aan dareerin, waana in lagu dhaqo wakhti ku habboon haddii maqaarka lagu rusheeyo. Aqoon-is-weydaarsiyada waa in la sii daayaa, qalabkuna waa inuu noqdaa mid hawada ku xiran. Hawl-wadeenadu waa inay xidhaan qalab ilaalin ah.

2. Dabci kara, midabka kaydinta dheer ayaa si tartiib tartiib ah u madoobanaya, hawadu degan tahay, laakiin marka qorraxdu soo baxdo si tartiib tartiib ah ayey u madoobaataa. Sublimation by kululaynta, oo leh ur phenol xanaaqa.

1. Waxa laga sameeyaa naphthalene iyada oo loo marayo sulfonation iyo alkali dhalaalay. dhalaalidda alkali sulfonation waa hab si weyn loo isticmaalo gudaha iyo dibadda, laakiin daxalka waa halis, kharashka waa badan yahay iyo isticmaalka oksijiinta noolaha biyaha wasakh ah waa mid sare. Habka 2-isopropylnaphthalene ee ay soo saartay Shirkadda American Cyanamid waxay qaadataa naphthalene iyo propylene sida alaabta ceeriin, waxayna soo saartaa 2-naphthol iyo acetone isku mar, taas oo la mid ah kiiska phenol ee habka isopropylbenzene. Kootada isticmaalka alaabta ceeriin: 1170kg/t naphthalene ganaax, 1080kg/t sulfuric acid, 700kg/t soodhaha caustic adag.

2. Kuleyli naphthalene-ka dhalaalaysa ilaa 140 ℃, oo leh saamiga naphthalene:sulfuric acid = 1:1.085 (molar ratio), sulfuric acid 98% 20min, iyo sulfuric acid 98% 20min.

Dareen-celinta waxay dhammaan doontaa marka maadada 2-naphthalenesulfonic acid ay gaarto in ka badan 66% iyo wadarta guud ee acidity waa 25% -27%, ka dibna falcelinta hydrolysis waxaa lagu sameyn doonaa 160 ℃ 1h, naphthalenes bilaash ah ayaa lagu afuufin doonaa uumiga biyaha. at 140-150 ℃, ka dibna cufnaanta qaraabo ee 1.14 naphthalenes waxaa lagu dari doonaa si tartiib ah iyo si siman at 80-90 ℃ ka hor. Xalka sodium sulfite waa dhexdhexaad ilaa warqadda tijaabada cas ee Kongo aysan isbeddelin buluug. Falcelinta gaaska sulfur dioxide ee wakhtiga ku habboon la soo saaro uumiga, alaabada dhexdhexaadinta ayaa la qaboojiyey ilaa 35 ~ 40 ℃ qaboojiyaha qaboojiyaha, nuugaya kiristaalo shaandhada leh 10% biyo milix ah, qalalan, oo lagu daray gobolka dhalaalay ee 98% sodium hydroxide at 300 ~ 310 ℃, walaaqaya oo joogteeyo 320 ~ 330 ℃, si ay saldhigga sodium 2-naphthalene sulfonate la isku daray si 2-naphthol sodium, ka dibna isticmaal biyo kulul si ay u milmaan dhalaalka salka, ka dibna u gudubto xagga sare dhexdhexaadiye sulfur dioxide ka dhashay falcelinta, falcelinta acidification at 70 ~ 80 ℃ ilaa phenolphthalein ahaa midab lahayn. Alaabta acidification-ku waxay noqon doonaan lakabyo joogto ah, lakabka sare ee dareeraha kululaynta si karkaraya, taagan, qaybsan lakabka aqueous, alaabta ceeriin ee 2-naphthol marka hore kulaylka fuuqbaxa, ka dibna distillation decompression, noqon kartaa alaabta saafi ah.

3. Habka soo saarista iyo crystallization si looga saaro 1-naphthol ee 2-naphthol. Isku qas 2-naphthol iyo biyo qayb ahaan iyo kulayl ilaa 95 ℃, marka 2-naphthol la dhalaaliyo, walaaq isku dar ah si xoog leh oo hoos u dhig heerkulka ilaa 85℃ ama wax ka badan, qabooji sheyga slurry ee kareemka leh heerkulka qolka oo shaandh. Waxa ku jira 1-naphthol waxaa lagu raad raaci karaa falanqaynta daahirsanaanta. 4.

Waxa laga soo saaray 2-naphthalenesulfonic acid by alkali dhalaalay [2].
