Gabatarwa

M-nitroaniline wani fili ne na kwayoyin halitta. Lura ce mai launin rawaya mai ƙamshi na musamman.

 

Babban amfani da m-nitroaniline shine a matsayin tsaka-tsakin rini kuma azaman ɗanyen abu don fashewa. Yana iya shirya wasu mahadi ta hanyar amsawa tare da wasu mahadi, irin su nitrate mahadi za a iya shirya ta hanyar amsawa tare da nitric acid, ko dinitrobenzoxazole za a iya shirya ta hanyar amsawa tare da thionyl chloride.

 

Hanyar shiri na m-nitroaniline za a iya samu ta hanyar amsawar m-aminophenol tare da nitric acid. Mataki na musamman shine a narkar da m-aminophenol a cikin sulfuric acid mai dauke da nitric acid da motsa halayen, sa'an nan kuma sanyi da crystallize don samun samfurin m-nitroaniline.

 

Bayanan tsaro: M-nitroaniline abu ne mai guba wanda ke da tasiri mai ban tsoro akan idanu, fata, da kuma numfashi. Haɗuwa da fata na iya haifar da kumburi da ja, kuma shakar tururi mai yawa ko ƙura na iya haifar da guba. Saka gilashin kariya, safar hannu, tufafi masu kariya, da na'urorin numfashi lokacin aiki, kuma tabbatar da cewa an gudanar da aikin a cikin yanayi mai kyau. Duk wani hulɗa da za a iya yi ya kamata a wanke shi da ruwa mai yawa kuma nan da nan a bi da shi tare da kulawar likita. Haka kuma, m-nitroaniline abu ne mai fashewa kuma yakamata a kiyaye shi daga buɗewar wuta da yanayin zafi.
