2-Cyano-5-methylpyridine (CAS# 1620-77-5) Isingeniso
1. Ukubukeka: uketshezi olungenambala ukuya kokuphuzi.
2. Iphuzu Elincibilikayo:-11 ℃.
3. Iphuzu elibilayo: 207-210 ℃.
4. Ukuncibilika: kuncibilika kancane emanzini, kuncibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether.Sebenzisa:
1. Isetshenziswa kabanzi ku-organic synthesis, ingasetshenziswa njenge-reagent, i-intermediate noma i-catalyst ukuze ibambe iqhaza ekuphenduleni okuhlukahlukene, njengokusabela kokwakheka kwe-C-C, ukusabela kwe-cyanide.
2. Ingabamba iqhaza ekuhlanganisweni kwe-pyridine, i-pyridine ketones nezinye izinhlanganisela eziphilayo.
3. Ingasetshenziswa nasezibulala-zinambuzane, imithi kanye neminye imikhakha.
Indlela:
Ingalungiswa ngomzila wokwenziwa olandelayo:
1. I-Pyridine ihlangana ne-methyl acetic anhydride ukuze ikhiqize i-5-methyl pyridine.
2. Sabela i-5-picoline ne-sodium cyanide ngaphansi kwezimo ze-alkaline ukuze ukhiqize a.
Ulwazi Lokuphepha:
1. Over kungokwakho compounds eziphilayo, kukhona ubuthi ethile, sicela ulandele izinqubo zokuphepha elabhorethri, unake izinyathelo zokuzivikela.
2. Gwema ukuthinta isikhumba, amehlo, njll. Uma kukhona ukuthintana, hlambulula ngokushesha ngamanzi amaningi. Uma kukhona ukungalungi kahle, sicela ufune usizo lwezokwelapha.
3. Lapho ugcina futhi uphatha, sicela ugweme izinga lokushisa eliphezulu, imithombo yomlilo, futhi ugcine indawo yokusebenza enomoya omuhle.
4. Uketshezi oluwudoti kufanele lulahlwe ngokuhambisana nemithetho yendawo ukuze kugwenywe ukungcoliswa kwemvelo.
Sicela uqaphele ukuthi ukusetshenziswa nokuphathwa kwezinto zamakhemikhali kufanele kulandele imithethonqubo efanele kanye nezinqubo zokusebenza eziphephile, futhi kulandele imihlahlandlela efanele yokusebenza kwelabhorethri.
