Intshayelelo
I-2,5-dimethylpyrazine yi-organic compound. Oku kulandelayo kukwaziswa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2,5-dimethylpyrazine.
Umgangatho:
I-2,5-Dimethylpyrazine yikristale engenambala ukuya kwi-yellow yellow kunye ne-smoky ekhethekileyo, i-nutty, kunye nephunga lekhofi.
Sebenzisa:
Indlela:
Ukulungiswa kwe-2,5-dimethylpyrazine kunokwenziwa ngeendlela ezahlukeneyo. Indlela eqhelekileyo kukufumana imveliso ekujoliswe kuyo nge-ammonolysis ye-thioacetylacetone elandelwa yi-cyclization. Ukongezelela, kukho ezinye iindlela zokudibanisa, ezifana ne-nitroation ye-carbon compounds, ukunciphisa i-acyl oxime, njl.
Ulwazi ngoKhuseleko:
I-2,5-Dimethylpyrazine ikhuselekile ngokufanelekileyo kubantu kunye nokusingqongileyo phantsi kweemeko eziqhelekileyo zokusetyenziswa
- Xa udibana nolusu kunye namehlo, kunokubangela ukucaphuka kunye nokuvuvukala, kwaye kufuneka kuthathwe amanyathelo okhuseleko xa uyisebenzisa, njengokugqoka iiglavu zokukhusela kunye nezibuko.
- Kuphephe ukuphefumla iigesi okanye uthuli ngexesha lokuphatha, njengoko ukuphefumla ixesha elide kunokubangela ukucaphuka kokuphefumula.
- Ukuqhagamshelana ne-oxidants kunye ne-acids eqinile kufuneka kugwenywe xa ugcina ukuphepha ukuphendula okuyingozi.
- Xa ulahla, lahla ngokuhambelana nemimiselo efanelekileyo kwaye ugweme ukukhutshwa ngokuthe ngqo kwindawo.
