Isingeniso
I-2-ethoxy-3-methylpyrazine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-2-ethoxy-3-methylpyrazine iwuketshezi olungenambala.
- I-Solubility: Incibilika emanzini, i-ethanol kanye nezincibilikisi eziningi eziphilayo.
Sebenzisa:
- Ingasetshenziswa ekuhlanganisweni kwemithi ethile elwa namagciwane (njenge-polyhydroxysulfamic acid), kanye nezinye izinhlanganisela eziphilayo ezisebenzayo.
Indlela:
- I-2-Ethoxy-3-methylpyrazine ngokuvamile ingalungiswa nge-transesterification ye-2-methylpyrazine nge-ethanol. Inqubo ethize ihlanganisa: ukushisa kokuqala nokushukumisa i-2-methylpyrazine ngenani elifanele le-ethanol ku-reactor, bese wengeza inani elithile le-alkyd catalyst (njenge-Fengyun acid), ukuqhubeka nokusabela kokushisa, futhi ekugcineni i-distilling ukuze uthole umkhiqizo.
Ulwazi Lokuphepha:
- Gqoka izinto zokuzivikela ezifanele njengamagilavu zelabhu, izibuko, nezingubo zokuzivikela phakathi nenqubo.
