Intshayelelo
I-2-Chloro-4-methylpyridine i-organic compound. Nalu ulwazi malunga neepropati zayo, ukusetyenziswa, iindlela zokuvelisa, kunye nokhuseleko:
Umgangatho:
- Ukubonakala: I-2-Chloro-4-methylpyridine i-crystalline eqinile emhlophe.
- Ukunyibilika: Inonyibiliko oluphantsi emanzini kodwa iyanyibilika kwizinyibilikisi zendalo ezifana neealkoholi kunye ne-ethers.
Sebenzisa:
- I-Chemical synthesis: I-2-chloro-4-methylpyridine idla ngokusetyenziswa njenge-reagent kunye ne-intermediate in organic synthesis. Ingasetyenziselwa njenge-reagent ye-chlorinated kwi-chemical reactions. Ngokomzekelo, inokusabela ngee-alcohol ukwenza i-ethers, kunye ne-aldehydes kunye ne-ketones ukwenza i-imine compounds, njl.
Indlela:
Kukho iindlela ezimbini eziqhelekileyo zokulungiselela:
- Indlela ye-1: I-2-chloro-4-methylpyridine ifunyenwe ngokuphendula i-2-methylpyridine nge-hydrogen chloride.
- Indlela ye-2: I-2-chloro-4-methylpyridine ifunyenwe ngokuphendula i-2-methylpyridine ngegesi ye-chlorine.
Ulwazi ngoKhuseleko:
- I-2-Chloro-4-methylpyridine inetyhefu kwaye inokucaphukisa amehlo, inkqubo yokuphefumula kunye nolusu. Izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, izixhobo zokuphefumla, kunye nezibuko kufuneka zinxitywe ngexesha lokusetyenziswa.
- Kufuneka igcinwe kwindawo eyomileyo, nengena umoya kakuhle, kude nemithombo yomlilo kunye ne-oxidants.
- Landela iinkqubo zokusebenza ezikhuselekileyo xa usebenzisa kwaye uphephe ukuxubana neminye imichiza. Kwimeko yokungenwa ngengozi, okanye ukudibana ngengozi nolusu, funa unyango ngokukhawuleza.
