3-Methoxy-2-nitropyridine (CAS# 20265-37-6) isingeniso
imvelo:
I-2-Nitro-3-methoxypyridine iqinile ngokubukeka kwekristalu okumhlophe kuya kokuphuzi okukhanyayo. Inephunga elinamandla futhi iyavutha.
Ukusetshenziswa: Ingasetshenziswa futhi njengezinto zokwenziwa zamadayi nezingulube.
Indlela yokukhiqiza:
I-2-Nitro-3-methoxypyridine ingalungiswa ngokusabela i-p-methoxyaniline nge-nitric acid. Indlela ethize yokuhlanganisa ingaba ukusabela kwe-nitrate ye-methoxyaniline, kulandelwa ukusabela kwe-2-nitro-3-methoxyaniline etholwe nge-acetone, futhi ekugcineni ukusabela kokuphelelwa amanzi emzimbeni.
Ulwazi lokuphepha:
I-2-Nitro-3-methoxypyridine ingaba yingozi emzimbeni womuntu njengoba ingabangela ukucasuka esikhumbeni, emehlweni, nasohlelweni lokuphefumula. Izinyathelo zokuphepha ezifanele kufanele zithathwe ngesikhathi sokusetshenziswa nokuphathwa, njengokugqoka izibuko zokuzivikela, amagilavu, namamaski. Qiniseka ukuthi ugwema ukuthintana nezinto ezivuthayo futhi ugweme ukuhogela uthuli lwazo, igesi, noma umhwamuko. Kufanele kuqashelwe ukuba kude nemithombo yomlilo nezinga lokushisa eliphezulu lapho usebenzisa futhi ugcina.
