3-Amino-6-fluoro-2-methylpyridine (CAS# 28489-47-6)
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. R41 – Ingozi yokulimala okubi emehlweni |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S39 – Gqoka ukuvikela iso / ubuso. |
| I-Hazard Class | I-IRRITANT |
Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C6H7FN2. Okulandelayo yisingeniso kwezinye zezakhiwo zayo, ukusetshenziswa, izindlela kanye nolwazi lokuphepha:
Imvelo:
1. Ukubukeka: Okuqinile kwekristalu engenambala ukuya kokuphuzi ngokuphaphathekile.
2. Iphuzu Elincibilikayo: cishe ku-82-85 ℃.
3. Iphuzu elibilayo: Cishe ku-219-221 ℃.
4. Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-ether ne-dichloromethane.
Sebenzisa:
Isetshenziswa kakhulu njengengxenye ephakathi ku-organic synthesis. Ingasetshenziselwa ukulungiselela izinhlobonhlobo zezinhlanganisela eziphilayo, njengezidakamizwa, izibulala-zinambuzane, odayi nama-ligands. Iphinde ibe nenani lesicelo elingase libe khona emkhakheni wezokwelapha.
Indlela:
ngokuvamile itholakala ngokusabela kwe-pyridine nge-reagent fluorinating kanye ne-amino reagent yokusabela kwe-methylation. Indlela ethile yokuhlanganisa ingalungiswa futhi ithuthukiswe ngokwezidingo zangempela.
Ulwazi Lokuphepha:
1. Ingase icasule amehlo, isikhumba kanye nesistimu yokuphefumula. Sebenzisa kufanele uqaphele ukugwema ukuthintana.
2. Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko zokuphepha namamaski okuzivikela phakathi nokusebenza.
3. Gwema ukuhogela uthuli, intuthu namagesi. Indawo yokusebenza kufanele ibe nomoya omuhle.
4. Uma ukuthintana ngephutha noma ukusetshenziswa kabi, kufanele ukugeza ngokushesha noma ukwelashwa.
