Intshayelelo
I-2-Methoxy-3-isopropylpyrazine, eyaziwa ngokuba yi-MIBP (i-Methoxyisobutylpyrazine), i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala
- Ivumba: Inevumba elifana nepepile eluhlaza
Sebenzisa:
Indlela:
I-2-Methoxy-3-isopropylpyrazine inokwenziwa ngala manyathelo alandelayo:
I-sodium sulfate kunye ne-sodium bicarbonate zisetyenziselwa ukulungisa ixabiso le-pH.
I-Pyrazine, isopropyl magnesium bromide, kunye ne-methanol isabela kwiqondo lokushisa elifanelekileyo.
Emva kokuba impendulo igqityiwe, i-compound ecocekileyo i-distilled kwaye i-crystallized.
Ulwazi ngoKhuseleko:
- I-2-Methoxy-3-isopropylpyrazine ine-toxicity ephantsi kodwa isafuna ukuphathwa ngokukhuselekileyo kweekhemikhali ukuba ilandelwe.
- Kulumkele ukudibana nolusu, amehlo kunye nenwebu. Kwimeko yoqhagamshelwano, hlambulula ngokukhawuleza ngamanzi amaninzi.
- Musa ukuphefumlela umphunga okanye uthuli olusuka kwikhompawundi.
- Xa isetyenziswa okanye igcinwe, yigcine kude nemithombo yomlilo kunye nezinto ezinokutsha.
- Kufuneka igcinwe kwindawo epholileyo, eyomileyo kwaye engenamoya kakuhle, kude neeasidi kunye nee-oxidants.
