Intshayelelo
I-6-CHLORO-4-METHYLPYRIDIN-3-CARBOXALDEHYDE (2-CHLORO-5-FORMYL-4-PICOLINE) YI-ORGANIC COMPOUND. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 6-Chloro-4-methylpyridine-3-carboxaldehyde ngulwelo olungenambala ukuya kumthubi.
- Ukunyibilika: Inokunyibilika kwizinyibilikisi ezininzi eziphilayo, njenge-ethanol, i-ether, kunye nekloroform.
- Uzinzo: Le khompawundi izinzile kubushushu begumbi, kodwa inokubola phantsi kobushushu, ilangatye, okanye iimeko ezineasidi kakhulu.
Sebenzisa:
- I-6-chloro-4-methylpyridine-3-carboxaldehyde yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye isetyenziswa rhoqo ekulungiseleleni ezinye izinto eziphilayo.
Indlela:
I-6-Chloro-4-methylpyridine-3-carboxaldehyde idla ngokulungiswa ngokusabela kwe-synthesis efana nala manyathelo alandelayo:
1. I-4-methylpyridine iphathwa nge-alkali ukufumana i-ion engalunganga ehambelana nayo.
2. Ii-ion ezingalunganga ziphendulwa nge-cuprous chloride ukwenza i-alkyl copper intermediates.
3. I-Alkyl copper intermediates isabela nge-formaldehyde ukwenza i-6-chloro-4-methylpyridine-3-carboxaldehyde.
Ulwazi ngoKhuseleko:
- I-6-Chloro-4-methylpyridine-3-carboxaldehyde inokuba yingozi kumzimba womntu, kwaye amanyathelo okhuseleko ayimfuneko kufuneka athathwe xa uyisebenzisa, njengokugqoka izixhobo ezifanelekileyo zokukhusela (ezifana neeglavu, izibuko, kunye nempahla yokukhusela).
- Kufuneka igcinwe kwindawo epholileyo, eyomileyo kwaye engenamoya, kude nomlilo kunye ne-oxidants.
- Gwema ukuphefumla, ukudibana kwesikhumba kunye nokungeniswa ngexesha lokuphatha kunye nokusetyenziswa.
- Ngokukhawuleza emva koqhagamshelwano, hlambulula indawo yesikhumba engcolileyo ngamanzi amaninzi kwaye ufune unyango.
