Diphenol ma aha hydrocarbon caraf udgoon sababtoo ah waxa ku jira atamka oksijiinta waana soosaar caraf udgoon.
Warshadaha 2-naphthol waa la safeeyey naphthol sida walxo ceeriin ah, oo leh 96-98% sulfuric acid sulfonation of 2-naphthol sulfonic acid, ka dibna la dhexdhexaadinta sodium sulfite si ay u abuurto milixdeeda sodium, ka dibna leh sodium hydroxide alkali fusion of 2-naphthol sodium , ka dibna leh acidification sulfuric acid of 2-naphthol alaabta ceeriin, ka dib markii karkaraya, dhaqidda, qalajinta, depressive Distillation of 2-naphthol alaabta.
Wasakhaynta habkani waa mid halis ah, dhibaatada ilaalinta deegaanka ayaa aad u muuqata.
Horumarinta cyanamine American ee 2-isopropylnaphthalene isku darka wax soo saarka acetone 2-naphthol, sababtoo ah kharashka ilaalinta deegaanka iyo sababo kale oo joojiyay wax soo saarka.
Waqtigan xaadirka ah, wadamada ugu badan ee wax soo saarka 2-naphthol ee adduunka waa Shiinaha, Hindiya, Japan, Talyaaniga iyo qaar ka mid ah wadamada ku yaal Bariga Yurub.
Shiinuhu waxa uu bilaabay in uu soo saaro 2-naphthol sannadkii 1957. Laga soo bilaabo 1980-meeyadii, markii waddamadii hore u maray ay joojiyeen wax soo saarka midba midka kale, Shiinuhu waxa uu noqday dalka ugu badan ee soo saara 2-naphthol.
Ilaa 1990kii, suuqa 2-naphthol waxa uu la kulmay kor u kac iyo hoos u dhac weyn. Sannadihii u dambeeyay, wax-soo-saarka sannadlaha ah ee 8-100 kun oo tan ayaa la joogteeyey, dhoofintu sidoo kale waxay ilaalisay koboc ballaaran, iyadoo la dhoofiyay 8,227 tan 2005, 15,924 tan 2006, iyo 15,307 tan bishii Janaayo ilaa Oktoobar 2007.
Isticmaalka 2-naphthol ee Shiinaha waxay ku saabsan tahay 60% dhexdhexaadiyeyaasha dheeha, 20% wax lagu daro caag, 10% midabada iyo midabada, iyo 10% kuwa kale.
Marka baahida loo qabo midabaynta iyo midabaynta ayaa kordheysa, sidaas oo kale baahida 2-naphthol.
Hagaajinta habka wax soo saarka, badbaadinta tamarta iyo yaraynta isticmaalka, yaraynta saddex qashinka ama horumarinta habka nadiifinta cusub waxay noqotay jihada muhiimka ah ee horumarinta joogtada ah iyo horumarka caafimaadka leh ee warshadaha wax soo saarka 2-naphthol.
Marka labaad, codsiga ee warshadaha dheeha iyo midabka
Dhexdhexaadiyeyaasha dheeha iyo midabka ayaa ah meelaha ugu badan ee laga isticmaalo 2-naphthol gudaha Shiinaha. Sababta ugu weyn ayaa ah in soo saarista dhexdhexaadiyeyaasha dheeha ay ku socotay wareejinta adduunka oo dhan. Tusaale ahaan, 2, 3 acids, J acid, γ acid, R acid iyo chromophenol AS dhamaantood waa dhoofinta dhexe ee muhiimka ah ee Shiinaha, taas oo ka dhigan in ka badan kala badh wax soo saarka gudaha.
Marka lagu daro isku-darka midabaynta iyo dhexdhexaadiyeyaasha midabka, 2-naphthol ayaa sidoo kale loo isticmaali karaa qayb azo ah, iyo xeryahooda diazo si ay u soo saaraan dheeha 1,2, 3 acids.
2, 3 aashitada magaca sayniska: 2-hydroxy-3-naphthic acid, habka uu u samaysan yahay waa [1]: 2-naphthol iyo sodium hydroxide reaction, decompressed fuuqbax, helaan 2-naphthol sodium, ka dibna ka falcelin CO2 si aad u hesho 2- naphthol iyo 2, 3 cusbo sodium, ka saar 2-naphthol, acidification, hel 2, 3 acid.
Waqtigan xaadirka ah, hababka ugu muhiimsan ee isku dhafan waa habka wejiga adag iyo habka dareeraha, iyo habka xalinta waa isbeddelka guud ee horumarka.
Midabka harada oo leh 2,3 asiidh sida qaybaha isku xidhka ayaa la isku daraa iyada oo marka hore qaybaha diazoo laga sameeyo cusbada diazo, oo ay weheliso 2,3 acids, ka dibna la isticmaalo birta alkali iyo alkali birta cusbada waxa loo rogi karaa midabyo haro ah oo aan la milmi karin.
chromatogramka ugu weyn ee 2,3 midabka harada aashitada waa iftiin cas.
Tusaale ahaan: CI Pigment Red 57:1, CI Pigment Cas 48:1, iwm.
2, 3 asiidh ayaa si weyn loogu isticmaalaa isku dhafka chromophenol ee midabaynta barafka. Tusmada Midabka ee 1992, 28 koromophenols ayaa lagu sameeyay 2, 3 acids.
Midabka phenol AS taxanaha qaybaha isku xidhka ee midabka azo, hababka synthetic ee noocan oo kale ah rinjiga waxaa laga sameeyaa qaybta diazo diazonium milix marka hore, iyo midabka phenol isku dhafka AS taxane ah derivatives, sida AS qaybaha diazo kaliya ka kooban yahay giraanta udgoon alkyl. halogen, nitrocellulose, kooxaha alkoksy, sida AS midabka caadiga ah ee ka dhashay falcelinta phenol AS taxane ah dheeha azo ee qaybaha isku dhafan,
Tusaale ahaan, giraanta udgoonka ee qaybaha diazo waxa kale oo ku jira kooxaha sulfonic acid, iyo chromophenol AS derivatives taxane ah, ka dibna cusbada alkali iyo alkali biraha dhulka waxaa loo rogi karaa midabada harooyinka aan la milmi karin.
MIT-Ivy INDUSTRY waxay u heellan tahay dheeha iyo dawooyinka dhex dhexaadinta muddo ku dhow 20 sano, oo leh nadiif sare iyo qiimo cadaalad ah, taas oo ay si weyn u amaaneen isticmaaleyaasha midabka gudaha iyo dibedda. Si loogu mahadceliyo tirada badan ee isticmaalayaasha jacaylka, muunadyada shirkadeena waxaa la siin karaa isticmaaleyaasha tijaabo bilaash ah, ku soo dhawoow isticmaaleyaasha dhammaan qeybaha bulshada si ay u yimaadaan si ay uga wada hadlaan iskaashiga!
