Mawu Oyamba

2-Methyl-4-nitroaniline ndi organic pawiri. Ndi kristalo wachikasu mpaka lalanje wokhala ndi kukhazikika kwabwino. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-methyl-4-nitroaniline:

 

Ubwino:

- Maonekedwe: Yellow to orange crystalline solidline

- Kusungunuka: Kusungunuka mu zosungunulira zina monga ethanol, chloroform ndi dimethyl sulfoxide.

 

Gwiritsani ntchito:

- Makampani opanga mankhwala: 2-methyl-4-nitroaniline angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic kuti synthesis wa mankhwala monga utoto, mankhwala ophera tizilombo ndi mabomba.

 

Njira:

Pali njira zingapo zokonzekera 2-methyl-4-nitroaniline:

- Direct nitrification: 2-methyl-4-aminoaniline imayendetsedwa ndi nitric acid yokhazikika kuti ipange 2-methyl-4-nitroaniline.

- Oxidation-nitrification: 2-methyl-4-bromoaniline imachitidwa ndi aniline peroxide yochulukirapo kenako ndi nitric acid yokhazikika kuti ipange 2-methyl-4-nitroaniline.

 

Zambiri Zachitetezo:

- 2-Methyl-4-nitroaniline ndi chophulika chomwe chingayambitse kuphulika chikayatsidwa kapena kutentha kwambiri.

- Pogwira 2-methyl-4-nitroaniline, valani zida zodzitetezera monga magolovesi, magalasi, ndi mikanjo, ndikuwonetsetsa kuti zikugwiritsidwa ntchito pamalo abwino mpweya wabwino.

- Pewani kukhudza khungu, maso, ndi kupuma.

- Pewani kukhudzana ndi zinthu zoyaka moto, zotulutsa okosijeni, ma asidi ndi zinthu zina panthawi yosungira komanso yoyendetsa.
