Intshayelelo
I-2-Acetyl-3-ethylpyrazine yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwekhompawundi:
Iipropati: I-2-acetyl-3-ethylpyrazine i-crystalline eqinile engenambala kunye nesakhiwo esikhethekileyo se-nitrogen heterocyclic. Inozinzo oluphezulu kunye nokungaguquki kwiqondo lokushisa. Inyibilika ngokulula kwezinye izinyibilikisi zendalo kwaye ayinyibiliki kancinci emanzini.
Ukusetyenziswa: I-2-acetyl-3-ethylpyrazine inoluhlu olubanzi lokusetyenziswa kwi-organic synthesis. Ingasetyenziswa njenge-catalyst esebenzayo kwizinto ezininzi ezibalulekileyo ze-organic reaction, ezifana ne-carbonylation, i-oxidation, kunye ne-amination.
Indlela yokulungiselela: Kukho iindlela ezininzi zokulungiselela i-2-acetyl-3-ethylpyrazine, kwaye indlela esetyenziswa ngokuqhelekileyo ifunyenwe ngokuphendula i-acetylformamide kunye ne-3-ethylpyrazine. Ngokukodwa, i-acetoformamide kunye ne-3-ethylpyrazine kuqala ixutywe, ishushu phantsi kweemeko ezifanelekileyo, kwaye ke imveliso ekujoliswe kuyo ifunyenwe nge-crystallization kunye nokucoca.
Inokucaphukisa amehlo, ulusu, kunye nenkqubo yokuphefumla, kunye nezixhobo ezifanelekileyo zokukhusela ezinjengeeglasi, iiglavu, iimaski zokukhusela kufuneka zinxitywe xa usebenza. Kwimeko yoqhagamshelwano ngengozi okanye ukuphefumla kule khompawundi, hlamba okanye udibane nogqirha ngokukhawuleza.
