Nhanganyaya
2-ethoxy-3-methylpyrazine isanganiswa yeorganic. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
- Kuonekwa: 2-ethoxy-3-methylpyrazine imvura isina ruvara.
- Solubility: Inonyungudika mumvura, ethanol uye yakawanda organic solvents.
Shandisa:
- Inogona kushandiswa mukugadzirwa kwemamwe mishonga inorwisa mabhakitiriya (yakadai se polyhydroxysulfamic acid), pamwe chete nemamwe biologically active compounds.
Nzira:
- 2-Ethoxy-3-methylpyrazine kazhinji inogona kugadzirirwa ne transesterification ye2-methylpyrazine ine ethanol. Iyo chaiyo nzira inosanganisira: kutanga kupisa uye kubvongodza 2-methylpyrazine ine chiyero chakakodzera che ethanol mu reactor, wobva wawedzera imwe alkyd catalyst (yakadai seFengyun acid), ichienderera mberi nekudziya kwekuita, uye pakupedzisira distilling kuti uwane chigadzirwa.
Zvekuchengetedza
- Pfeka midziyo yekudzivirira yakakodzera senge magurovhosi erabhoritari, magirazi uye zvipfeko zvekudzivirira panguva yekuita.
