Taw qhia
Sudan IV. yog ib tug hluavtaws organic dye nrog cov tshuaj npe ntawm 1-(4-nitrophenyl)-2-oxo-3-methoxy-4-nitrogenous heterobutane.
Sudan IV. yog ib tug liab crystalline hmoov uas yog soluble nyob rau hauv organic solvents xws li ethanol, dimethyl ether thiab acetone, thiab insoluble nyob rau hauv dej.
Txoj kev npaj ntawm Sudan dyes IV. Feem ntau yog tau los ntawm cov tshuaj tiv thaiv ntawm nitrobenzene nrog nitrogenous heterobutane. Cov kauj ruam tshwj xeeb yog thawj zaug ua rau nitrobenzene nrog nitrogenous heterobutane nyob rau hauv acidic tej yam kev mob los tsim ib tug precursor compound ntawm Sudan IV. Tom qab ntawd, nyob rau hauv qhov kev txiav txim ntawm ib tug oxidizing tus neeg sawv cev, lub precursor compounds yog oxidized mus rau lub kawg Sudan IV. khoom.
Nws tuaj yeem ua rau khaus khaus ntawm daim tawv nqaij, qhov muag, thiab ua pa, thiab yuav tsum tau siv nrog cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg. Sudan dyes IV. muaj qee yam toxicity thiab yuav tsum tau zam nyob rau hauv kev sib cuag ncaj qha los yog noj. Thaum siv thiab khaws cia, yuav tsum tau saib xyuas kom tsis txhob muaj oxidants lossis combustibles.
