Nhanganyaya
4-Methyl-2-nitroaniline, inozivikanwawo semethyl yellow, inhengo yeorganic. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
-Kuonekwa: Methyl yero ndeyero makristasi kana crystalline poda.
-Solubility: Methyl yero inenge isinganyungudika mumvura, asi inonyungudika mune zvakawanda organic zvinonyungudutsa zvakaita sedoro, ethers, uye benzene.
Shandisa:
-Kemikari yepakati: Methyl yero inowanzoshandiswa seyakakosha yepakati mukugadzirwa kwedhayi, pigment, fluorescents uye organic optoelectronic zvinhu.
- Biomarkers: Methyl yero inogona kushandiswa seye fluorescent labeler yemasero uye biomolecules, iyo inoshandiswa muzvidzidzo zvebiology uye minda yekurapa.
- Enamel uye ceramic pigment: Methyl yero inogona zvakare kushandiswa semuvara weenamel uye ceramics.
Nzira:
- Methyl yero inogadzirwa nenzira dzakasiyana-siyana, uye imwe yenzira dzakajairika ndeyekuisanganisa nemethylation ye nitroaniline. Izvi zvinogona kuwanikwa nekuita kwe methanol uye thionyl chloride pamberi peiyo acid catalyst.
Zvekuchengetedza
- Methyl yero muchetura musanganiswa unogumbura uye unogona kukuvadza vanhu nenharaunda.
- Midziyo yekudzivirira yega senge magurovhosi ekudzivirira, magirazi uye gown zvinodiwa kana uchishanda.
- Dzivisa inhalation, kubata neganda nemaziso, kudzivirira kupinza, uye shandisa mhepo yakakodzera kana zvichidikanwa.
- Paunenge uchichengeta uye uchibata methyl yero, tevera yakakodzera kuchengetedza maitiro uye mirau.
