Intshayelelo

ISudan emthubi yikhompawundi ephilayo enegama lekhemikhali iSudan I. Oku kulandelayo yintshayelelo yendalo, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lweSudan Yellow:

 

Umgangatho:

ISudan emthubi ngumgubo o-orenji-tyheli ukuya kubomvu-mdaka wekristale yomgubo kunye nencasa ekhethekileyo yequnube. I-soluble kwi-ethanol, i-methylene chloride kunye ne-phenol kwaye ayinyibiliki emanzini. I-Sudan etyheli izinzile ekukhanyeni kunye nobushushu, kodwa ibola lula phantsi kweemeko zealkaline.

 

Usetyenziso: Isenokusetyenziswa kwishishini ledayi nepeyinti, kunye nebala lemakroskopu kuvavanyo lwebhayoloji.

 

Indlela:

Umthubi waseSudan unokulungiswa kukusabela kwe-amines enevumba elimnandi njenge-aniline kunye ne-benzidine ene-aniline methyl ketone. Ekuphenduleni, i-amine enevumba elimnandi kunye ne-aniline methyl ketone ifumana ukutshintshiselana kwe-amine kubukho besodium hydroxide ukwenza iSudan emthubi.

 

Ulwazi ngoKhuseleko: Ukutya ixesha elide okanye okugqithisileyo kweSudan emthubi kunokubeka imingcipheko ethile yempilo ebantwini. Ukusetyenziswa kweSudan yellow kufuna ulawulo olungqongqo lwedosi kunye nokuthotyelwa kwemimiselo kunye nemigangatho efanelekileyo. Ukongeza, umthubi waseSudan kufuneka kwakhona uthintele ukunxibelelana nolusu okanye ukuphefumla uthuli lwayo, nto leyo enokubangela ukuchasana okanye ukucaphuka kokuphefumla.
