Intshayelelo

I-Sudan B yidayi ye-synthetic ye-organic enegama lekhemikhali i-Sauermann Red G. Yeqela le-azo ledayi kwaye ine-orenji-red crystalline powdery substance.

ISudan B iphantse yanganyibiliki emanzini, kodwa inonyibiliko olulungileyo kwizinyibilikisi zendalo. Inokukhanya okulungileyo kunye nokuxhathisa amathumba kwaye ingasetyenziselwa ukudaya izinto ezifana nempahla, iphepha, ufele kunye neeplastiki.

Indlela yokulungiselela iSudan B ilula, kwaye indlela eqhelekileyo kukusabela i-dinitronaphthalene kunye ne-2-aminobenzaldehyde, kwaye ufumane iimveliso ezicocekileyo ngokusebenzisa amanyathelo enkqubo njengokunciphisa kunye nokuhlaziya.

Nangona iSudan B isetyenziswa kakhulu kushishino lokudaya, iyityhefu kwaye ine-carcinogenic. Ukungeniswa okuphezulu kweSudan B kunokubangela umonakalo kumzimba womntu, njengeziphumo eziyityhefu esibindini nasezintso.
