Gabatarwa
4-Methyl-2-nitroaniline, wanda kuma aka sani da methyl yellow, wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin sa, amfaninsa, hanyoyin masana'anta da bayanan aminci:
inganci:
- Bayyanar: Methyl rawaya shine lu'ulu'u na rawaya ko foda crystalline.
- Solubility: Methyl yellow kusan ba zai iya narkewa a cikin ruwa, amma mai narkewa a cikin wasu kaushi da yawa kamar su alcohols, ethers, da benzene.
Amfani:
- Matsakaicin sinadarai: Methyl yellow sau da yawa ana amfani da shi azaman matsakaici mai mahimmanci a cikin haɗin dyes, pigments, fluorescents da kayan aikin optoelectronic.
- Alamar halitta: Methyl yellow za a iya amfani da shi azaman alamar mai kyalli ga sel da biomolecules, waɗanda ake amfani da su a cikin gwaje-gwajen halittu da filayen likitanci.
- Enamel da yumbu pigments: Methyl yellow kuma za a iya amfani da matsayin colorant ga enamels da tukwane.
Hanya:
- Methyl yellow an shirya ta hanyoyi daban-daban, kuma ɗayan hanyoyin gama gari shine haɗa shi ta hanyar methylation na nitroaniline. Ana iya samun wannan ta hanyar amsawar methanol da thionyl chloride a gaban mai haɓaka acid.
Bayanin Tsaro:
- Methyl yellow sinadari ne mai guba wanda ke da ban haushi kuma yana iya cutar da mutane da muhalli.
- Ana buƙatar kayan kariya na sirri kamar safar hannu na kariya, tabarau da riguna yayin aiki.
-A guji shakar numfashi, tuntuɓar fata da idanu, guje wa sha, da amfani da iskar da ta dace idan ya cancanta.
- Lokacin adanawa da sarrafa methyl yellow, bi hanyoyin aminci da ƙa'idodi masu dacewa.
