Intshayelelo
I-2-Methoxypyrimidine i-organic compound. Yikristale eqinileyo emhlophe kunye nevumba elikhethekileyo. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-methoxypyrazine:
Umgangatho:
- Imbonakalo: Ikristale emhlophe eqinileyo
- Ukunyibilika: Inyibilika kwiialkoholi, ii-ethers kunye nezinyibilikisi ze-ester, zinyibilika kancinane emanzini
Sebenzisa:
- I-2-Methoxypyrazine ingasetyenziselwa kwishishini ledayi ukudibanisa idayi yezinto eziphilayo.
Indlela:
- I-2-Methoxypyrazine idla ngokufunyanwa ngokusabela kwe-2-hydroxypyrazine kunye ne-methanol. I-2-Hydroxypyrazine iphendulwa kunye nefomati yesodium okanye i-sodium carbonate ukwenza ityuwa yesodium ehambelanayo, kwaye emva koko i-methanol engaphezulu yongezwa ukuphumeza ukusabela kwiqondo lokushisa elifanelekileyo kunye nexesha lokuphendula. Imveliso ye-2-methoxypyrazine yafunyanwa ngonyango lwe-acidic, i-crystallization, ukomisa kunye namanye amanyathelo.
Ulwazi ngoKhuseleko:
- I-2-Methoxypyrazine iyacaphukisa kwaye kufuneka igwenywe ekudibaneni nolusu kunye namehlo.
-Thatha amanyathelo okhuseleko xa uyisebenzisa, njengokunxiba ukhuseleko lwamehlo kunye nesiphefumlo.
-Kuphephe ukuphefumla, ukungeniswa, okanye ukudibana nothuli, iigesi, okanye izicombululo zekhompawundi.
- Qinisekisa iimeko ezifanelekileyo zokungenisa umoya ngexesha lokusebenza.
- Gcina i-2-methoxypyrazine kwindawo eyomileyo, epholileyo, nengenamoya kakuhle kude nomlilo kunye ne-oxidants.
