Isingeniso
I-2-Chloro-4-methylpyridine iyinhlanganisela yezinto eziphilayo. Nalu olunye ulwazi mayelana nezakhiwo zayo, ukusetshenziswa, izindlela zokukhiqiza, nokuphepha:
Ikhwalithi:
- Ukubukeka: I-2-Chloro-4-methylpyridine iyikristale eqinile emhlophe.
- Ukunyibilika: Inokuncibilika okuphansi emanzini kodwa iyancibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether.
Sebenzisa:
- Ukwakhiwa kwamakhemikhali: I-2-chloro-4-methylpyridine ivame ukusetshenziswa njenge-reagent futhi iphakathi ku-organic synthesis. Ingasetshenziswa njenge-reagent ene-chlorine ekuphenduleni kwamakhemikhali. Isibonelo, ingasabela ngama-alcohol ukuze kwakhiwe ama-ether, nama-aldehydes nama-ketones ukuze enze izinhlanganisela ze-imine, njll.
Indlela:
Kunezindlela ezimbili ezijwayelekile zokulungiselela:
- Indlela yoku-1: I-2-chloro-4-methylpyridine itholakala ngokuphendula i-2-methylpyridine nge-hydrogen chloride.
- Indlela yesi-2: I-2-chloro-4-methylpyridine itholakala ngokuphendula i-2-methylpyridine ngegesi ye-chlorine.
Ulwazi Lokuphepha:
- I-2-Chloro-4-methylpyridine inobuthi futhi ingacasula amehlo, uhlelo lokuphefumula, nesikhumba. Izimpahla zokuzivikela ezifanele njengamagilavu, ama-respirators, nezibuko kufanele zigqokwe ngesikhathi sokusetshenziswa.
- Kufanele igcinwe endaweni eyomile, enomoya omuhle, kude nemithombo yomlilo kanye nama-oxidants.
- Landela izinqubo zokusebenza eziphephile lapho usebenzisa futhi ugweme ukuxubana namanye amakhemikhali. Uma ungenwa ngephutha, noma ukuthinta isikhumba ngephutha, funa usizo lwezempilo ngokushesha.
