Mawu Oyamba
4-Methyl-2-nitroaniline, yemwenso amadziwika kuti methyl yellow, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: Methyl yellow ndi makhiristo achikasu kapena ufa wa crystalline.
- Kusungunuka: Methyl yellow imakhala pafupifupi yosasungunuka m'madzi, koma imasungunuka mu zosungunulira zambiri monga ma alcohols, ethers, ndi benzene.
Gwiritsani ntchito:
- Mankhwala apakati: Methyl yellow nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati pakupanga utoto, utoto, ma fluorescents ndi zida za organic optoelectronic.
- Biomarkers: Methyl yellow angagwiritsidwe ntchito ngati fulorosenti labeler kwa maselo ndi biomolecules, amene amagwiritsidwa ntchito mu kuyesera kwachilengedwenso ndi madera azachipatala.
- Enamel ndi ma ceramic pigment: Methyl yellow itha kugwiritsidwanso ntchito ngati utoto wa enamel ndi zoumba.
Njira:
- Methyl yellow imakonzedwa m'njira zosiyanasiyana, ndipo imodzi mwa njira zodziwika bwino ndikuyipanga ndi methylation ya nitroaniline. Izi zitha kupezedwa ndi zomwe methanol ndi thionyl chloride pamaso pa chothandizira asidi.
Zambiri Zachitetezo:
- Methyl yellow ndi mankhwala oopsa omwe amakwiyitsa komanso owopsa kwa anthu komanso chilengedwe.
- Zida zodzitetezera monga magolovesi, magalasi ndi mikanjo zimafunikira mukamagwira ntchito.
- Pewani kutulutsa mpweya, kukhudzana ndi khungu ndi maso, kupewa kudya, komanso kugwiritsa ntchito mpweya wabwino ngati kuli kofunikira.
- Mukasunga ndikugwira methyl yellow, tsatirani njira zoyendetsera chitetezo ndi malamulo oyenera.
