Taw qhia

Sudan daj yog ib qho organic compound nrog cov tshuaj npe Sudan I. Cov hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm Sudan Yellow:

Zoo:

Sudan daj yog txiv kab ntxwv-daj rau reddish-xim av crystalline hmoov nrog ib tug tshwj xeeb strawberry tsw. Nws yog soluble hauv ethanol, methylene chloride thiab phenol thiab insoluble hauv dej. Sudan daj yog ruaj khov rau lub teeb thiab kub, tab sis yog yooj yim decomposed nyob rau hauv alkaline tej yam kev mob.

Kev Siv: Nws kuj tuaj yeem siv rau hauv kev lag luam dyeing thiab xim, nrog rau lub tshuab tsom iav hauv kev sim tshuaj lom neeg.

Txoj kev:

Sudan daj tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm cov tshuaj tsw qab amines xws li aniline thiab benzidine nrog aniline methyl ketone. Nyob rau hauv cov tshuaj tiv thaiv, aromatic amine thiab aniline methyl ketone undergo amine pauv cov tshuaj tiv thaiv nyob rau hauv lub xub ntiag ntawm sodium hydroxide los ua Sudan daj.

Cov Lus Qhia Txog Kev Nyab Xeeb: Ntev ntev lossis ntau dhau ntawm Sudan daj tuaj yeem ua rau muaj kev phom sij rau tib neeg. Kev siv Sudan daj yuav tsum muaj kev tswj hwm nruj ntawm kev siv tshuaj thiab ua raws li cov cai thiab cov qauv. Tsis tas li ntawd, Sudan daj yuav tsum tsis txhob sib cuag nrog daim tawv nqaij lossis nqus tau nws cov plua plav, uas tuaj yeem ua rau muaj kev tsis haum tshuaj lossis ua pa ua pa.

Yav dhau los: Yellow 14 CAS 842-07-9
