Taw qhia
M-nitroaniline yog ib qho organic compound. Nws yog daj crystalline hmoov nrog ib tug peculiar foul tsw.
Kev siv tseem ceeb ntawm m-nitroaniline yog cov xim nruab nrab thiab ua cov khoom siv rau cov khoom tawg. Nws tuaj yeem npaj lwm cov tebchaw los ntawm kev ua haujlwm nrog qee cov tebchaw, xws li cov tshuaj nitrate tuaj yeem npaj los ntawm kev ua haujlwm nrog nitric acid, lossis dinitrobenzoxazole tuaj yeem npaj los ntawm kev ua haujlwm nrog thionyl chloride.
Txoj kev npaj ntawm m-nitroaniline tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm m-aminophenol nrog nitric acid. Cov kauj ruam tshwj xeeb yog kom yaj m-aminophenol nyob rau hauv sulfuric acid uas muaj nitric acid thiab do cov tshuaj tiv thaiv, ces txias thiab crystallize thaum kawg tau txais cov khoom ntawm m-nitroaniline.
Cov ntaub ntawv kev nyab xeeb: M-nitroaniline yog cov tshuaj lom neeg uas muaj kev cuam tshuam rau lub qhov muag, tawv nqaij, thiab ua pa. Kev sib cuag nrog daim tawv nqaij tuaj yeem ua rau mob thiab liab, thiab nqus tau pa ntau ntawm vapor lossis plua plav tuaj yeem ua rau lom. Hnav cov tsom iav tiv thaiv, hnab looj tes, khaub ncaws tiv thaiv, thiab lub tshuab ua pa thaum ua haujlwm, thiab xyuas kom meej tias kev ua haujlwm tau ua tiav nyob rau hauv qhov cua zoo. Txhua qhov kev sib cuag yuav tsum tau muab yaug nrog dej kom txaus thiab kho tam sim nrog kev kho mob. Ntxiv mus, m-nitroaniline yog tawg thiab yuav tsum tau ceev kom deb ntawm qhov qhib nplaim taws thiab kub kub.
