Mawu Oyamba

Sudan yellow ndi mankhwala okhala ndi dzina lachi Sudan I. Zotsatirazi ndizofotokozera za chilengedwe, kagwiritsidwe ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha Sudan Yellow:

 

Ubwino:

Sudan yellow ndi ufa wonyezimira-wachikasu mpaka kufiira-bulauni wokhala ndi kukoma kwapadera kwa sitiroberi. Imasungunuka mu ethanol, methylene chloride ndi phenol ndipo imasungunuka m'madzi. Yellow ya Sudan imakhala yokhazikika pakuwala komanso kutentha, koma imawola mosavuta pansi pamikhalidwe yamchere.

 

Ntchito: Itha kugwiritsidwanso ntchito pamakampani opanga utoto ndi utoto, komanso banga la maikulosikopu pakuyesa kwachilengedwe.

 

Njira:

Sudan yellow itha kukonzedwa ndi zomwe amines onunkhira monga aniline ndi benzidine ndi aniline methyl ketone. Pochita izi, amine onunkhira ndi aniline methyl ketone amakumana ndi kusintha kwa amine pamaso pa sodium hydroxide kupanga Sudan chikasu.

 

Chidziwitso cha Chitetezo: Kudya kwanthawi yayitali kapena mopitilira muyeso wachikasu ku Sudan kumatha kubweretsa ngozi zina kwa anthu. Kugwiritsa ntchito chikasu cha Sudan kumafuna kuwongolera mosamalitsa mlingo ndikutsata malamulo ndi miyezo yoyenera. Komanso, Sudan yellow ayenera kupewa kukhudzana ndi khungu kapena inhalation wa fumbi lake, zomwe zingachititse thupi lawo siligwirizana kapena kupuma kuyabwa.
