Isingeniso

I-1,1′-[(phenylmethylene) bis[(2-methoxy-4,1-phenyl)azo]]di-2-naphthol, eyaziwa nangokuthi i-AO60, iwudayi wokwenziwa wemvelo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Izakhiwo: I-AO60 iyimpushana yekristalu ephuzi kuya kokubomvu, engancibiliki emanzini, encibilika kuzincibilikisi zemvelo ezifana ne-methanol, i-ethanol ne-chloroform. Izinzile ezimweni ezine-acidic, hlangothi kanye ne-alkaline.

 

Ukusetshenziswa: I-AO60 isetshenziswa kakhulu njengodayi kanye nenkomba. Ingasetshenziswa njenge-ejenti yokudaya yezindwangu, ikakhulukazi umphumela wokudaya wemicu yemvelo efana nekotini nelineni. Ingasetshenziselwa ukufaka imibala kumapulasitiki kanye nerabha. Ibuye isetshenziswe ngokujwayelekile njengenkomba ye-acid-base kanye nokunqunywa kwe-pH.

 

Indlela yokulungiselela: Ukulungiswa kwe-AO60 ngokuvamile kutholakala ngokuhlanganisa ukusabela kwe-nitrous acid ne-styrene, bese kusabela nge-2-naphthol ukwenza umkhiqizo okuhlosiwe.
