Intshayelelo
I-2-Ethyl-3-methylpyrazine yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-2-ethyl-3-methylpyrazine ikwi-liquid engenambala okanye i-crystalline form eqinileyo.
- Ukunyibilika: Inonyibiliko oluphantsi emanzini, kodwa inokunyibilika kwizinyibilikisi zendalo.
- Ukuzinza: Yikhompawundi ezinzile, kodwa ukudibanisa kunye ne-oxidants eqinile kunye ne-acids eqinile kufuneka kugwenywe.
Sebenzisa:
- I-2-Ethyl-3-methylpyrazine i-reagent esetyenziswa ngokuqhelekileyo kwaye iphinda isetyenziswe njengendawo ephakathi kwi-chemical synthesis.
Indlela:
I-2-Ethyl-3-methylpyrazine inokulungiswa ngezi ndlela zilandelayo:
- I-Ethyl bromide iqala ukusabela ngepyrazine ukuvelisa i-2-ethylpyrazine phantsi kweemeko ze-alkaline.
- Emva koko, i-2-ethylpyrazine iphendulwa nge-methyl bromide ukunika i-2-ethyl-3-methylpyrazine yokugqibela.
Ulwazi ngoKhuseleko:
- I-2-Ethyl-3-methylpyrazine ngokuqhelekileyo ithathwa njengetyhefu ephantsi, kodwa i-protocols efanelekileyo yokhuseleko kufuneka ilandelwe.
- Kuphephe ukuphefumla, ukudibana nolusu kunye namehlo, kwaye unxibe izixhobo zokuzikhusela ezifana neeglavu, iiglavu, kunye nezikhuselo zobuso.
- Xa ugcina kwaye uphatha, yigcine kude nemithombo yokutshisa kunye ne-oxidizing agents ukuphepha ingozi yomlilo kunye nokudubula.
- Jonga kuncwadi olufanelekileyo lokhuseleko kunye namaxwebhu edatha yokhuseleko anikezelwe ngumthengisi ngolwazi oluthe vetshe kunye noluchanekileyo ngokhuseleko.
