Isingeniso
I-2-Chloro-4-methyl-3-nitropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Izakhiwo: I-2-Chloro-4-methyl-3-nitropyridine iqinile engenambala ukuya kokuphuzi ngokukhanyayo nephunga elimnandi. Ayincibiliki emanzini futhi iyancibilika kuzincibilikisi zemvelo njenge-ethanol ne-dimethylformamide. Inobuthi obukhulu.
Ukusetshenziswa: I-2-chloro-4-methyl-3-nitropyridine isetshenziswa kakhulu njengento ebalulekile ephakathi nendawo kanye neyokwenziwa kohlaza ku-organic synthesis. Ingasetshenziswa futhi ekulungiseleleni izakhiwo zensimbi kanye nama-catalysts.
Indlela yokulungiselela: Ukulungiswa kwe-2-chloro-4-methyl-3-nitropyridine kuvame ukuqala nge-2-chloro-4-methylpyridine. Okokuqala, i-2-chloro-4-methylpyridine yasabela nge-nitric acid egxilile, bese umkhiqizo ucwecwe futhi uhlanzwe ukuze uthole i-2-chloro-4-methyl-3-nitropyridine.
Ulwazi Lokuphepha: I-2-Chloro-4-methyl-3-nitropyridine into enobuthi engase ibangele ukulimala kwezempilo uma ichayeka noma ihogelwa kuhwanqa, izimpushana, noma izixazululo. Kuyacasula futhi kuyazwela futhi kufanele kugwenywe ukuthintana nesikhumba, amehlo, kanye nomgudu wokuphefumula. Izinyathelo ezifanele zokuphepha kufanele zithathwe lapho uphatha noma ulondoloza, njengokugqoka izinto zokuzivikela ezifanele (isb., amagilavu, izibuko, namamaski). Uma usebenzisa, qinisekisa indawo enomoya omuhle futhi ugweme ukuthintana nezinto ezivuthayo. Noma iyiphi imfucuza ehlobene ne-2-chloro-4-methyl-3-nitropyridine kufanele ilahlwe ngokuhambisana nemithetho yendawo. Lapho usebenzisa noma uphatha lesi sithako, izinqubo ezifanele zokusebenza zokuphepha nemihlahlandlela kufanele ilandelwe ngokuqinile.
