Isingeniso

I-Sudan B ingudayi wokwenziwa wemvelo onegama lekhemikhali i-Sauermann Red G. Iyingxenye yeqembu le-azo lodayi futhi inomphumela oyimpushana oyikristale owolintshi.

I-Sudan B cishe ayincibiliki emanzini, kodwa inokuncibilika okuhle kuzincibilikisi zemvelo. Inokukhanya okuhle futhi imelana namathumba futhi ingasetshenziselwa ukudaya izinto ezifana nezindwangu, iphepha, isikhumba namapulasitiki.

Indlela yokulungiselela ye-Sudan B ilula uma kuqhathaniswa, futhi indlela evamile iwukusabela i-dinitronaphthalene nge-2-aminobenzaldehyde, nokuthola imikhiqizo ehlanzekile ngezinyathelo zenqubo ezifana nokunciphisa kanye nokwenza kabusha ikristalu.

Nakuba iSudan B isetshenziswa kakhulu embonini yokudaya, inobuthi futhi inomdlavuza. Ukungena okuphezulu kwe-Sudan B kungase kubangele umonakalo emzimbeni womuntu, njengemiphumela enobuthi esibindini nasezinso.

Okwedlule: I-P-Yellow 147 CAS 4118-16-5
