Intshayelelo
I-2-ethoxy-3-methylpyrazine yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Ukubonakala: I-2-ethoxy-3-methylpyrazine ngulwelo olungenambala.
- Ukunyibilika: Inyibilika emanzini, i-ethanol kunye nezona zinyibilikisi zininzi.
Sebenzisa:
- Ingasetyenziswa ekudibaneni kwamayeza athile okubulala iintsholongwane (afana ne-polyhydroxysulfamic acid), kunye nezinye iikhompawundi zebhayoloji ezisebenzayo.
Indlela:
- I-2-Ethoxy-3-methylpyrazine ngokubanzi ingalungiswa nge-transesterification ye-2-methylpyrazine nge-ethanol. Inkqubo ethile ibandakanya: ukufudumeza kokuqala kunye nokuvuselela i-2-methylpyrazine kunye nenani elifanelekileyo le-ethanol kwi-reactor, ngoko ukongeza inani elithile le-alkyd catalyst (njenge-Fengyun acid), ukuqhubeka nokufudumala, kwaye ekugqibeleni i-distilling ukufumana imveliso.
Ulwazi ngoKhuseleko:
- Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neglavu zelebhu, iiglasi, kunye nempahla yokukhusela ngexesha lenkqubo.
