Isingeniso
I-2-Methoxypyrimidine iyinhlanganisela yezinto eziphilayo. Iqinile njengekristalu emhlophe enephunga elingavamile. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-methoxypyrazine:
Ikhwalithi:
- Ukubukeka: Okuqinile kwekristalu emhlophe
- Ukunyibilika: Kuncibilika kuma-alcohols, ethers nezincibilikisi ze-ester, kuncibilika kancane emanzini
Sebenzisa:
- I-2-Methoxypyrazine ingasetshenziswa futhi embonini kadayi ukuze kuhlanganiswe odayi bemvelo.
Indlela:
- I-2-Methoxypyrazine ivame ukutholwa ngokusabela kwe-2-hydroxypyrazine ne-methanol. I-2-Hydroxypyrazine isabela nge-sodium formate noma i-sodium carbonate ukuze yakhe usawoti we-sodium ohambisanayo, bese kwengezwa i-methanol eyeqile ukuze yenze ukusabela ngesikhathi esifanele sokushisa nangesikhathi sokusabela. Umkhiqizo we-2-methoxypyrazine watholwa ngokwelashwa kwe-asidi, i-crystallization, ukomiswa nezinye izinyathelo.
Ulwazi Lokuphepha:
- I-2-Methoxypyrazine iyacasula futhi kufanele igwenywe ukuthintana nesikhumba namehlo.
- Thatha izinyathelo zokuphepha lapho uyisebenzisa, njengokugqoka iso nokuvikela ukuphefumula.
- Gwema ukuhogela, ukudonsa, noma ukuthintana nothuli, amagesi, noma izixazululo zenhlanganisela.
- Qinisekisa izimo ezinhle zokungenisa umoya ngesikhathi sokusebenza.
- Gcina i-2-methoxypyrazine endaweni eyomile, epholile, nengena umoya kahle kude nomlilo nama-oxidants.
