Okwu mmalite
4-Methyl-2-nitroaniline, nke a makwaara dị ka methyl yellow, bụ ngwakọta organic. Ndị a bụ mmalite nke akụrụngwa ya, ojiji ya, ụzọ nrụpụta ya na ozi nchekwa:
Ogo:
- Ọdịdị: Methyl odo bụ kristal edo edo ma ọ bụ ntụ ntụ kristal.
- Solubility: Methyl odo fọrọ nke nta ka ọ ghara ịsacha na mmiri, mana soluble n'ọtụtụ ihe mgbaze organic dị ka alcohols, ethers, na benzene.
Jiri:
- Chemical intermediates: Methyl odo na-ejikarị dị ka ihe dị mkpa etiti na njikọ nke e ji esiji, pigments, fluorescents na organic optoelectronic ihe.
- Biomarkers: Methyl odo nwere ike iji dị ka fluorescent labeler maka cell na biomolecules, nke a na-eji na ndu nnwale na ọgwụ ubi.
- Enamel na seramiiki pigmenti: Methyl odo nwekwara ike iji dị ka agba maka enamels na seramiki.
Usoro:
- A na-akwadebe methyl yellow n'ụzọ dịgasị iche iche, na otu n'ime ụzọ ndị a na-emekarị bụ iji mejupụta ya site na methylation nke nitroaniline. Enwere ike nweta nke a site na mmeghachi omume nke methanol na thionyl chloride n'ihu onye na-emepụta acid.
Ozi nchekwa:
- Methyl yellow bụ ihe na-egbu egbu nke na-akpasu iwe ma nwee ike imerụ mmadụ na gburugburu ebe obibi.
- Ngwa nchedo onwe onye dị ka uwe mkpuchi, ugogbe anya na uwe mwụda ka achọrọ mgbe ị na-arụ ọrụ.
- Zere iku ume, ịkpọtụrụ akpụkpọ ahụ na anya, zere iri nri, ma jiri ikuku ikuku kwesịrị ekwesị ma ọ bụrụ na ọ dị mkpa.
- Mgbe ị na-echekwa ma na-ejikwa methyl yellow, soro usoro na ụkpụrụ nchekwa dị mkpa.
