3-Cyano-4-methylpyridine (CAS#5444-01-9)
3-Cyano-4-methylpyriridine ke motsoako oa manyolo o nang le motsoako oa lik'hemik'hale C7H6N2. E latelang ke tlhaloso e qaqileng ea sebopeho sa eona, tšebeliso, tokiso le tlhahisoleseling ea polokeho:
Tlhaho:
-Ponahalo: 3-Cyano-4-methylpyriridine ke kristale e tšoeu ho ea mosehla.
- Sebaka sa ho qhibiliha: Sebaka sa eona se qhibilihisang ke likhato tse 66-69 tsa Celsius.
-Solubility: E na le ho qhibiliha ho fokolang ka metsing 'me e qhibiliha ka har'a metsoako e mengata ea tlhaho, e kang ethanol, ether le chloroform.
Sebelisa:
-E le organic synthesis reagent: 3-Cyano-4-methylpyriridine e ka sebelisoa e le reagent bakeng sa motsoako oa metsoako e meng ea lintho tse phelang, tse kang chefo e bolaeang likokoanyana, meriana le dae.
-E le ts'usumetso: E ka boela ea sebelisoa e le tšubuhlellano liketsong tse ling tsa catalytic.
Mokhoa oa ho itokisa:
3-Cyano-4-methylpyriridine e ka lokisoa ka mekhoa e latelang:
1. pyridine le acetonitrile li kena ka lebaka la cyanation ho hlahisa 3-cyanopyridine, ebe li kena ka methylation reaction ho hlahisa 3-Cyano-4-methylpyriridine.
2. Methyl pyridine e sebetsana le hydrogen cyanide ho hlahisa 3-Cyano-4-methylpyriridine tlas'a catalysis ea alkali.
Lintlha tsa Tšireletseho:
Thepa ea lik'hemik'hale tsa3-Cyano-4-methylpyridineha li so ithutoe ka botlalo, ka hona hoa hlokahala ho latela mekhoa e akaretsang ea laboratori ea lik'hemik'hale. Apara lisebelisoa tse loketseng tsa ho itšireletsa tse kang liatlana tse sireletsang, likhalase le lijase tsa laboratori nakong ea ts'ebeliso. E lokela ho bolokoa le ho tšoaroa ka nepo ho qoba ho kopana le lintho tse kang li-oxidants tse matla. Nakong ea ts'ebetso, tlhokomelo e lokela ho lefshoa ho thibela ho inhalation, ho kopana le letlalo kapa ho kenngoa. Haeba kotsi e amanang le eona e etsahala ka mokhoa o sa tsotelleng, mehato ea phekolo ea tšohanyetso e lokela ho nkoa ka nako. Tsebo ea k'hemistri le boiphihlelo ba laboratori mabapi le ho sebetsana le komporo ho netefatsa ts'ebetso e bolokehileng. E le ho utloisisa haholoanyane polokeho ea eona, ka kopo sheba lintlha tse amehang tsa ts'ireletso ea tekheniki kapa ikopanye le setsebi.
