Mawu Oyamba
2-ethoxy-3-methylpyrazine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: 2-ethoxy-3-methylpyrazine ndi madzi opanda mtundu.
- Kusungunuka: Kusungunuka m'madzi, ethanol ndi zosungunulira zambiri za organic.
Gwiritsani ntchito:
- Itha kugwiritsidwa ntchito popanga maantibayotiki ena (monga polyhydroxysulfamic acid), komanso mankhwala ena achilengedwe.
Njira:
- 2-Ethoxy-3-methylpyrazine nthawi zambiri imatha kukonzedwa ndi transesterification ya 2-methylpyrazine ndi ethanol. Njira yeniyeni imaphatikizapo: Kutentha koyamba ndi kusonkhezera 2-methylpyrazine ndi mlingo woyenera wa ethanol mu riyakitala, ndiyeno kuwonjezera kuchuluka kwa alkyd chothandizira (monga Fengyun acid), kupitiriza kutentha, ndipo potsiriza distilling kupeza mankhwala.
Zambiri Zachitetezo:
- Valani zida zodzitetezera zoyenera monga magolovesi a labu, magalasi, ndi zovala zodzitchinjiriza panthawi yomwe mukukonza.
