I-3-Methoxy-2-nitropyridine (CAS # 20265-37-6) intshayelelo
indalo:
I-2-Nitro-3-methoxypyridine iqinile kunye nembonakalo yekristale emhlophe ukuya kokukhanya emthubi. Inevumba elinamandla kwaye iyatsha.
Ukusetyenziswa: Isenokusetyenziswa njengemathiriyeli yokwenziwa kwedayi kunye neepigments.
Indlela yokuvelisa:
I-2-Nitro-3-methoxypyridine inokulungiswa ngokuphendula i-p-methoxyaniline nge-nitric acid. Indlela ethile yokudibanisa inokuba yi-nitration reaction ye-methoxyaniline, ilandelwa yi-reaction ye-2-nitro-3-methoxyaniline efunyenweyo kunye ne-acetone, kwaye ekugqibeleni i-dehydration reaction.
Ulwazi lokhuseleko:
I-2-Nitro-3-methoxypyridine inokuba yityhefu emzimbeni womntu njengoko inokubangela ukucaphuka kwesikhumba, amehlo kunye nenkqubo yokuphefumla. Amanyathelo afanelekileyo okhuseleko kufuneka athathwe ngexesha lokusetyenziswa kunye nokuphathwa, njengokunxiba iiglavu zokukhusela, iiglavu, kunye nemaski. Qiniseka ukuba uyakuphepha ukudibana nezinto ezinokutsha kwaye uphephe ukuphefumlela uthuli, igesi, okanye umphunga. Ingqalelo kufuneka ihlawulwe ekugcineni kude nemithombo yomlilo kunye neendawo ezingqongileyo zobushushu obuphezulu xa usebenzisa kwaye ugcina.
