Gabatarwa

Nitrobenzene) wani fili ne na kwayoyin halitta wanda zai iya zama farin kristal mai ƙarfi ko ruwan rawaya mai ƙamshi na musamman. Mai zuwa gabatarwa ne ga wasu kaddarorin, amfani, hanyoyin shiri da bayanan aminci na nitrobenzene:

 

inganci:

Nitrobenzene ba ya narkewa a cikin ruwa amma yana narkewa a cikin kaushi na halitta kamar alcohols da ethers.

Ana iya samun shi ta hanyar nitrating benzene, wanda aka samar ta hanyar amsa benzene tare da maida hankali na nitric acid.

Nitrobenzene wani abu ne mai tsayayye, amma kuma yana da fashewa kuma yana da babban wuta.

 

Amfani:

Nitrobenzene abu ne mai mahimmancin sinadari mai mahimmanci kuma ana amfani dashi ko'ina a cikin haɗin kwayoyin halitta.

Nitrobenzene kuma ana iya amfani dashi azaman ƙari a cikin kaushi, fenti da sutura.

 

Hanya:

Hanyar shiri na nitrobenzene galibi ana samun ta ta hanyar nitrification na benzene. A cikin dakin gwaje-gwaje, ana iya haxa benzene da nitric acid da aka tattara da kuma sulfuric acid mai mai da hankali, a jujjuya shi a ƙananan zafin jiki, sa'an nan kuma kurkure da ruwan sanyi don samun nitrobenzene.

 

Bayanin Tsaro:

Nitrobenzene wani fili ne mai guba, kuma bayyanarwa ko shakar tururinsa na iya haifar da lahani ga jiki.

Abu ne mai ƙonewa kuma mai fashewa kuma yakamata a guji hulɗa da tushen kunnawa.

Ya kamata a sanya kayan kariya na sirri kamar safar hannu na kariya da tabarau yayin sarrafa nitrobenzene, kuma ya kamata a kiyaye yanayin aiki mai cike da iska.

A yayin da ruwa ko hadari ya faru, ya kamata a dauki matakan da suka dace don tsaftacewa da zubar da shi. Bi dokokin da suka dace don zubar da sharar da aka samar yadda ya kamata.
