Nhanganyaya
2-Methoxypyrimidine is an organic compound. Iro jena rekristaro rakasimba rine kunhuhwirira kwakasiyana. Izvi zvinotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2-methoxypyrazine:
Hunhu:
-Kuonekwa: White crystalline yakasimba
- Solubility: Soluble mudoro, ethers uye ester solvents, zvishoma soluble mumvura
Shandisa:
- 2-Methoxypyrazine inogona zvakare kushandiswa muindasitiri yedhayi kugadzira organic dhayi.
Nzira:
- 2-Methoxypyrazine inowanzowanikwa nekuita kwe2-hydroxypyrazine uye methanol. 2-Hydroxypyrazine inobatwa nesodium formate kana sodium carbonate kuti igadzire inowirirana sodium munyu, uyezve yakawandisa methanol inowedzerwa kuti iite maitiro panguva yakakodzera tembiricha uye nguva yekuita. Iyo 2-methoxypyrazine chigadzirwa chakawanikwa neacidic kurapwa, crystallization, kuomesa uye mamwe matanho.
Zvekuchengetedza
- 2-Methoxypyrazine inogumbura uye inofanira kudzivirirwa kubva pakusangana neganda nemaziso.
- Tora chenjedzo paunenge uchiishandisa, sekupfeka maziso uye kudzivirira kwekufema.
- Dzivisa kufema, kupinza, kana kubata neguruva, magasi, kana mhinduro dzemukomboni.
- Ita shuwa mamiriro akanaka emhepo panguva yekushanda.
- Chengeta 2-methoxypyrazine munzvimbo yakaoma, inotonhorera, ine mhepo yakanaka kure nemoto uye oxidants.
