Isingeniso
I-2-Chloro-3-methoxypyridine(2-Chloro-3-methoxypyridine) iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C6H6ClNO. Iwuketshezi olungenambala olunephunga elimnandi. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: uketshezi olungenambala
Isisindo samangqamuzana: 159.57g/mol
I-Melting Point: Akwaziwa
Iphuzu elibilayo: 203-205 ℃
-Ukuminyana: 1.233g/cm3
-Ukunyibilika: Kuncibilika ku-ethanol, ether kanye nama-hydrocarbon ane-chlorine
Sebenzisa:
- I-2-Chloro-3-methoxypyridine ivamise ukusetshenziswa njengendawo ephakathi kokusabela kwe-organic synthesis.
-Emkhakheni wezokwelapha, ingasetshenziswa ukwenza ama-intermediate emithi kanye nezidakamizwa ezisebenzayo.
Indlela Yokulungiselela:
Indlela yokulungiselela ye-2-Chloro-3-methoxypyridine itholakala ikakhulukazi ngokusabela kwe-protonation kanye ne-chlorination ye-pyridine. Izindlela ezithile zokwenziwa zingaba:
1. i-pyridine esabelayo nge-hydrogen chloride ukuze ithole i-chloropyridine;
2. I-methanol ne-sodium hydroxide yengezwa kusixazululo se-chloropyridine ukuze kukhiqizwe umkhiqizo, ohlanjululwayo ukuze uthole i-2-Chloro-3-methoxypyridine.
Ulwazi Lokuphepha:
- I-2-Chloro-3-methoxypyridine iyinhlanganisela yezinto eziphilayo futhi iyacasula. Ukuthintana ngqo nesikhumba namehlo kufanele kugwenywe.
-Ngesikhathi sokuphatha noma ukugcinwa, kufanele kuthathwe izinyathelo zokuzivikela ezifanele futhi kugqokwe izinto zokuzivikela ezifana namagilavu nezibuko.
-Gwema ukuhogela umhwamuko noma isisombululo ngesikhathi sokuwusebenzisa futhi uwugcine unomoya omuhle.
-Gwema ukuthintana nama-oxidants aqinile, ama-asidi aqinile nezinye izinto ukuze uvimbele ukusabela okuyingozi.
-Ngemva kokusetshenziswa noma ukulahlwa, amakhemikhali asele kufanele alahlwe ngokuphepha nangokuhambisana nemithetho efanele yokuphepha kwemvelo.
