2-Cyano-5-methylpyridine (CAS# 1620-77-5) Intshayelelo
1. Imbonakalo: ayinambala ukuya kulwelo olutyheli.
2. Indawo enyibilikayo:-11 ℃.
3. Indawo yokubilisa: 207-210 ℃.
4. Ukunyibilika: kunyibilika kancinane emanzini, kunyibilika kwizinyibilikisi eziphilayo ezifana neealkoholi kunye neeethers.Sebenzisa:
1. Isetyenziswa ngokubanzi kwi-organic synthesis, ingasetyenziselwa njenge-reagent, i-intermediate okanye i-catalyst yokuthatha inxaxheba kwiindlela ezahlukeneyo zokuphendula, ezifana ne-C-C bond formation reaction reaction, i-cyanide reaction.
2. Inokuthatha inxaxheba kwi-synthesis ye-pyridine, i-pyridine ketones kunye nezinye izinto eziphilayo.
3. Inokusetyenziswa nakwizitshabalalisi, amayeza kunye nezinye iindawo.
Indlela:
Inokulungiswa ngale ndlela ilandelayo yokwenziwa:
1. I-Pyridine iphendula kunye ne-methyl acetic anhydride ukuvelisa i-5-methyl pyridine.
2. Yenza i-5-picoline kunye ne-sodium cyanide phantsi kweemeko ze-alkali ukuvelisa a.
Ulwazi ngoKhuseleko:
1. I-Over iyingxenye ye-organic compounds, kukho ubuthi obuthile, nceda ulandele iinkqubo zokhuseleko lwebhubhoratri, ubeke ingqalelo kumanyathelo okukhusela.
2. Gwema ukudibanisa nesikhumba, amehlo, njl. Ukuba kukho ukudibanisa, hlambulula ngokukhawuleza ngamanzi amaninzi. Ukuba kukho nayiphi na impazamo, nceda ufune unyango.
3. Ekugcinweni nasekuphatheni, nceda ugweme ukushisa okuphezulu, imithombo yomlilo, kunye nokugcina indawo yokusebenza enomoya.
4. Ulwelo oluyinkunkuma kufuneka ilahlwe ngokuhambelana nemigaqo yendawo ukuthintela ukungcoliseka kwendalo.
Nceda uqaphele ukuba ukusetyenziswa kunye nokuphathwa kwezinto zeekhemikhali kufuneka kulandele imimiselo efanelekileyo kunye neenkqubo zokusebenza ezikhuselekileyo, kwaye ulandele izikhokelo zokusebenza ezifanelekileyo zelabhoratri.
