I-3-Cyano-4-methylpyridine (CAS#5444-01-9)
I-3-Cyano-4-methylpyriridine iyinhlanganisela ye-organic ene-chemical formula C7H6N2. Okulandelayo incazelo eningiliziwe yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-3-Cyano-4-methylpyriridine iyi-crystalline eqinile emhlophe kuya kokuphuzi.
-Indawo yokuncibilika: Iphuzu layo lokuncibilika lingama-66-69 degrees Celsius.
-Ukunyibilika: Inokuncibilika okuphansi emanzini futhi incibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-ether ne-chloroform.
Sebenzisa:
-Njenge-organic synthesis reagent: I-3-Cyano-4-methylpyriridine ingasetshenziswa njenge-reagent yokuhlanganiswa kwamanye ama-organic compounds, njengezibulala-zinambuzane, imithi kanye namadayi.
-Njenge-catalyst: Ingasetshenziswa futhi njenge-catalyst kokunye ukusabela kwe-catalytic.
Indlela Yokulungiselela:
I-3-Cyano-4-methylpyriridine ingalungiswa ngezindlela ezilandelayo:
1. I-pyridine ne-acetonitrile zithola ukusabela kwe-cynation ukuze zikhiqize i-3-cyanopyridine, bese zibhekana nokusabela kwe-methylation ukukhiqiza i-3-Cyano-4-methylpyriridine.
2. I-Methyl pyridine ihlangana ne-hydrogen cyanide ukuze ikhiqize i-3-Cyano-4-methylpyriridine ngaphansi kwe-catalysis ye-alkali.
Ulwazi Lokuphepha:
Izici zamakhemikhali ze3-Cyano-4-methylpyridineazizange zifundwe ngokugcwele, ngakho-ke kuyadingeka ukulandela izinqubo zaselabhorethri yamakhemikhali jikelele. Gqoka izinto zokuzivikela ezifanele ezifana namagilavu okuzivikela, izibuko kanye namajazi aselabhorethri ngesikhathi sokusebenzisa. Kufanele igcinwe futhi iphathwe ngendlela efanele ukugwema ukuthintana nezinto ezifana nama-oxidants aqinile. Ngesikhathi sokusebenza, ukunakwa kufanele kukhokhwe ukuvimbela ukuhogela, ukuthintana kwesikhumba noma ukungenwa. Uma ingozi ehlobene yenzeka ngokunganaki, izinyathelo zokwelapha eziphuthumayo kufanele zithathwe ngesikhathi. Ulwazi lwamakhemikhali kanye nesipiliyoni saselabhorethri ekuphatheni i-compound ukuqinisekisa ukuphathwa okuphephile. Ukuze uqonde kabanzi ukuphepha kwayo, sicela uhlole imininingwane yobuchwepheshe yokuphepha efanele noma uxhumane nochwepheshe.
