Intshayelelo
I-2-Chloro-4-methyl-3-nitropyridine i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Iipropati: I-2-Chloro-4-methyl-3-nitropyridine yinto eqinileyo engenambala ukuya kumthubi ekhanyayo kunye nevumba elimnandi. Ayinyibiliki emanzini kwaye inyibilika kwii-solvents eziphilayo ezifana ne-ethanol kunye ne-dimethylformamide. Inetyhefu kakhulu.
Ukusetyenziswa: I-2-chloro-4-methyl-3-nitropyridine isetyenziswa ikakhulu njengento ebalulekileyo ephakathi kunye neyokwenziwa kwezinto eziluhlaza kwi-organic synthesis. Inokusetyenziswa kwakhona ekulungiseleleni izakhiwo zetsimbi kunye ne-catalysts.
Indlela yokulungiselela: Ukulungiswa kwe-2-chloro-4-methyl-3-nitropyridine ngokuqhelekileyo kuqala nge-2-chloro-4-methylpyridine. Okokuqala, i-2-chloro-4-methylpyridine yaphendulwa nge-nitric acid egxininisiweyo, kwaye emva koko imveliso yaxutywa kwaye yahlanjululwa ukuze ifumane i-2-chloro-4-methyl-3-nitropyridine.
Ulwazi loKhuseleko: I-2-Chloro-4-methyl-3-nitropyridine yinto enetyhefu enokubangela ingozi kwimpilo ukuba ibonakaliswe okanye ifakwe kwimiphunga yayo, i-powders, okanye izisombululo. Iyacaphukisa kwaye iyakhathaza kwaye kufuneka igwenywe ekudibaneni nolusu, amehlo kunye nomgudu wokuphefumla. Amanyathelo afanelekileyo okhuseleko kufuneka athatyathwe xa uphatha okanye ugcina, njengokunxiba izixhobo ezifanelekileyo zokukhusela (umz., iiglavu, iiglasi, kunye nemaski). Xa usetyenziswa, qinisekisa indawo enomoya omhle kwaye ugweme ukudibanisa nezinto ezinokutsha. Nayiphi na inkunkuma enxulumene ne-2-chloro-4-methyl-3-nitropyridine kufuneka ilahlwe ngokuhambelana nemimiselo yendawo. Xa usebenzisa okanye uphatha le khompawundi, iinkqubo zokusebenza ezifanelekileyo zokhuseleko kunye nezikhokelo kufuneka zilandelwe ngokungqongqo.
