Mawu Oyamba
4-Ethylpyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha 4-ethylpyridine:
Ubwino:
- Maonekedwe: Madzi opanda mtundu kapena olimba a crystalline.
- Kusungunuka: Kusungunuka m'madzi ambiri osungunulira, osasungunuka m'madzi.
Gwiritsani ntchito:
- Monga zosungunulira: 4-ethylpyridine imakhala ndi solubility yabwino ndipo imagwiritsidwa ntchito ngati zosungunulira kapena sing'anga, makamaka mu kaphatikizidwe ka organic, zomwe zimatha kulimbikitsa kupita patsogolo kwa zomwe zimachitika.
- Catalyst: 4-ethylpyridine itha kugwiritsidwanso ntchito ngati chothandizira pazinthu zina za organic, monga Grignard reagent reactions ndi hydrogenation reaction.
Njira:
- 4-Ethylpyridine ikhoza kukonzedwa ndi zomwe 2-ethylpyridine ndi ethyl acetate, kawirikawiri pansi pa zinthu zamchere.
Zambiri Zachitetezo:
- 4-Ethylpyridine imakwiyitsa ndipo imatha kuyambitsa kuyabwa m'maso, pakhungu, komanso pakhungu. Valani zida zodzitetezera zoyenera mukamagwira ntchito ndipo pewani kukhudzana mwachindunji ndi khungu, maso, kapena mpweya wopumira.
- Mukamagwiritsa ntchito kapena kusunga, sungani 4-ethylpyridine kutali ndi kutentha kwambiri komanso malawi otseguka.
- Potaya zinyalala, ndikofunikira kuzitaya motsatira malamulo ndi malamulo amderalo kuti apewe kuwononga chilengedwe.
