Diphenol ma aha hydrocarbon udgoon sababtoo ah waxa ku jira atamka oksijiinta waana wax laga soo saaro udgoon.
2-naphthol warshadeed waa naphthol la safeeyey oo ah walxo cayriin ah, oo leh 96-98% sulfonation sulfonation oo ah 2-naphthol sulfonic acid, ka dibna leh dhexdhexaadinta sodium sulfite si loo soo saaro cusbada sodium, ka dibna leh isku-darka sodium hydroxide alkali ee 2-naphthol sodium, ka dibna leh aashitada sulfuric acid ee alaabada cayriin ee 2-naphthol, ka dib marka la karkariyo, la dhaqo, la qalajiyo, la kala furfuro oo la sifeeyo alaabada 2-naphthol.
Wasakhowga habkan waa mid aad u daran dhibaatada ilaalinta deegaankana waa mid aad u muuqata.
Horumarinta cyanamine-ka Mareykanka ee 2-isopropylnaphthalene oo isku-darka ah ee habka acetone 2-naphthol, sababtoo ah kharashka ilaalinta deegaanka iyo sababo kale iyo joojinta wax soo saarka.
Waqtigan xaadirka ah, wadamada ugu muhiimsan ee wax soo saarka 2-naphthol ee adduunka waa Shiinaha, Hindiya, Japan, Talyaaniga iyo qaar ka mid ah wadamada Bariga Yurub.
Shiinaha wuxuu bilaabay inuu soo saaro 2-naphthol sanadkii 1957. Tan iyo 1980-meeyadii, markii wadamada horumaray ay midba midka kale joojiyeen wax soo saarka, Shiinuhu wuxuu noqday iibiyaha ugu weyn ee 2-naphthol.
Tan iyo 1990, suuqa 2-naphthol wuxuu la kulmay kor u kac iyo hoos u dhac weyn. Sannadihii ugu dambeeyay, wax soo saarka sanadlaha ah ee 8-100 kun oo tan ayaa la ilaaliyay, dhoofinta ayaa sidoo kale sii waday koboc weyn, iyadoo dhoofinta ay ahayd 8,227 tan sannadkii 2005, 15,924 tan sannadkii 2006, iyo 15,307 tan laga bilaabo Janaayo ilaa Oktoobar 2007.
Isticmaalka 2-naphthol ee Shiinaha waa qiyaastii 60% dhexdhexaadiyeyaasha rinjiga, 20% waxyaabaha lagu daro ee caagga ah, 10% midabada iyo midabada, iyo 10% kuwa kale.
Marka baahida loo qabo midabada iyo midabyada ay sii kordheyso, waxaa sidoo kale sii kordhaya baahida loo qabo 2-naphthol.
Hagaajinta habka wax soo saarka, keydinta tamarta iyo yaraynta isticmaalka, yaraynta saddex qashin ama horumarinta habka nadiifinta cusub ayaa noqotay jihada muhiimka ah ee horumarinta joogtada ah ee caafimaadka leh ee warshadaha wax soo saarka 2-naphthol.
Marka labaad, codsiga warshadaha rinjiga iyo midabka
Midabada iyo midabyada dhexdhexaadka ah ayaa ah meelaha ugu badan ee laga isticmaalo 2-naphthol ee Shiinaha. Sababta ugu weyn ayaa ah in soo saarista midabyada dhexdhexaadka ah ay ku socotay wareejinta adduunka oo dhan. Tusaale ahaan, 2, 3 asiidh, J acid, γ acid, R acid iyo chromophenol AS dhammaantood waa dhoofinta dhexdhexaadka ah ee muhiimka ah ee Shiinaha, taasoo ka dhigan in ka badan kala bar wadarta wax soo saarka gudaha.
Marka laga soo tago isku-darka midabaynta iyo dhexdhexaadinta midabka, 2-naphthol waxaa sidoo kale loo isticmaali karaa qayb azo ah, iyo isku-darka diazo si loo soo saaro midabaynta 1, 2, 3 asiidh.
2, 3 Magaca cilmiyeed ee aashitada: 2-hydroxy-3-naphthic acid, habka isku-darka waa [1]: 2-naphthol iyo falgalka sodium hydroxide, fuuq-baxa la cadaadiyay, hel 2-naphthol sodium, ka dibna falgal leh CO2 si aad u hesho 2-naphthol iyo 2, 3 sodium milix, ka saar 2-naphthol, aashitada, hel 2, 3 acid.
Waqtigan xaadirka ah, hababka ugu muhiimsan ee isku-darka waa habka marxaladda adag iyo habka dareeraha, habka dareeraha ahna waa isbeddelka guud ee horumarka.
Midabada harada oo leh 2,3 asiidh oo ah qaybaha isku xidhka ayaa marka hore la sameeyaa iyadoo qaybaha diazo laga dhigo cusbo diazo ah, oo lagu daro 2,3 asiidh, ka dibna iyadoo la isticmaalayo birta alkali iyo cusbada birta alkali dhulka waxaa loo rogi karaa midabyo harada aan milmi karin.
Koromogaraamka ugu weyn ee 2,3 midab oo harada aashitada ah waa iftiin cas.
Tusaale ahaan: CI Pigment Red 57:1, CI Pigment Red 48:1, iwm.
2, 3 asiidh ayaa si weyn loogu isticmaalaa isku-darka taxanaha chromophenol ee midabaynta barafka. Tusmada Midabaynta ee 1992, 28 chromophenols ayaa lagu sameeyay 2, 3 asiidh.
Midabka phenol AS taxane ah oo ka kooban qaybaha isku xidhka ee midabka azo, hababka macmal ah ee noocan rinjiga ah waxaa laga sameeyay cusbada diazonium ee diazonium marka hore, iyo midabka isku xidhka phenol AS taxane ah oo ka kooban waxyaabo ka soo jeeda, sida qaybaha diazo waxay ka kooban yihiin oo keliya giraanta udgoonka alkyl, halogen, nitrocellulose, kooxaha alkoxy, sida AS midabka caadiga ah ee ka dhasha falcelinta phenol AS taxane ah oo ah rinji azo ah oo loogu talagalay qaybaha isku xidhka,
Tusaale ahaan, giraanta udgoonka leh ee qaybaha diazo waxay sidoo kale ka kooban tahay kooxaha aashitada sulfonic, iyo noocyada taxanaha chromophenol AS, ka dibna milixda biraha dhulka alkali iyo alkali waxaa loo rogi karaa midabyo harada aan milmi karin.
MIT-Ivy INDUSTRY waxay ka go'nayd midabaynta iyo daawooyinka dhexdhexaadka ah muddo ku dhow 20 sano, iyadoo leh nadiifnimo sare iyo qiimo macquul ah, taas oo ay si weyn u ammaaneen dadka isticmaala midabka gudaha iyo dibadda. Si loogu mahadceliyo tirada badan ee isticmaalayaasha jacaylkooda, muunado shirkaddeenna ah ayaa loo fidin karaa isticmaalayaasha si ay u helaan tijaabo bilaash ah, soo dhawoow isticmaalayaasha ka kala socda dhammaan qaybaha bulshada si ay uga wada hadlaan iskaashiga!
