Isingeniso
I-4-Methyl-2-nitroaniline, eyaziwa nangokuthi i-methyl yellow, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-methyl ephuzi iyikristalu ephuzi noma i-crystalline powder.
- Ukunyibilika: I-methyl ephuzi icishe ingancibiliki emanzini, kodwa incibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, i-ethers, ne-benzene.
Sebenzisa:
- I-Chemical intermediate: I-Methyl yellow ivame ukusetshenziswa njengento ebalulekile emaphakathi ekuhlanganiseni kodayi, ama-pigments, ama-fluorescents nezinto ze-organic optoelectronic.
- Ama-Biomarkers: I-Methyl yellow ingasetshenziswa njengelebula le-fluorescent lamaseli nama-biomolecules, elisetshenziswa ekuhlolweni kwebhayoloji nasezinkundleni zezokwelapha.
- I-Enamel kanye nezingulube ze-ceramic: I-Methyl yellow ingasetshenziswa futhi njengombala we-koqweqwe lwawo kanye nezitsha zobumba.
Indlela:
- I-Methyl yellow ilungiswa ngezindlela ezihlukahlukene, futhi enye yezindlela ezivamile ukuyihlanganisa nge-methylation ye-nitroaniline. Lokhu kungatholwa ngokusabela kwe-methanol ne-thionyl chloride phambi kwe-catalyst ye-asidi.
Ulwazi Lokuphepha:
- I-Methyl yellow iyinhlanganisela enobuthi ecasulayo futhi engase ibe yingozi kubantu nasemvelweni.
- Izinto zokuzivikela ezinjengamagilavu okuzivikela, izibuko kanye nezingubo ziyadingeka lapho usebenza.
- Gwema ukuhogela, ukuthinta isikhumba namehlo, gwema ukudla, futhi usebenzise umoya ofanele uma kunesidingo.
- Lapho ugcina futhi uphatha i-methyl ephuzi, landela izinqubo ezifanele zokusebenza nemithethonqubo yokuphepha.
