Yellow 44 CAS 2478-20-8
Taw qhia
Solvent Yellow 44 tseem hu ua Sudan Yellow G hauv chemistry, thiab nws cov qauv tshuaj yog chromate ntawm Sudan Yellow G. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: Solvent Yellow 44 yog crystalline hmoov los ntawm txiv kab ntxwv-daj mus rau reddish-daj.
- Solubility: soluble nyob rau hauv dej, methanol, ethanol, insoluble nyob rau hauv ether, benzene thiab lwm yam organic solvents.
Siv:
- Tshuaj dyes: hnyav daj 44 tuaj yeem siv los ua cov xim dyes thiab daim ntawv lo reagents.
Txoj kev:
Cov kuab tshuaj daj 44 feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm sodium chromate nrog Sudan daj G hauv cov tshuaj aqueous.
Cov ntaub ntawv kev nyab xeeb:
- Solvent Yellow 44 yog cov tshuaj zas xim thiab yuav tsum tau ua tib zoo saib xyuas kom tsis txhob nqus cov plua plav lossis kev sib cuag ntawm daim tawv nqaij, qhov muag, thiab lwm yam.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv thaum siv.
- Thaum nqus tau los yog tawv nqaij, yaug tam sim ntawd nrog dej ntau thiab nrhiav kev pab kho mob.
- Thaum lub sij hawm cia, cov kuab tshuaj daj 44 yuav tsum muab tso rau hauv qhov chaw qhuav, txias, zoo-ventilated kom tsis txhob muaj kev sib cuag nrog hluav taws kub, oxidants los yog lwm yam reactive tshuaj.
Feem ntau, kev siv cov kuab tshuaj daj 44 yuav tsum tau ua raws li cov txheej txheem kev ua haujlwm nyab xeeb thiab raws li thaj chaw thov tshwj xeeb thiab cov kev cai tswj hwm.
