Mawu Oyamba

2-Acetyl-3-methylpyrazine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera, ndi chidziwitso cha chitetezo cha mankhwalawa:

 

Ubwino:

- Maonekedwe: 2-Acetyl-3-methylpyrazine ndi yolimba yachikasu yotuwa.

- Kusungunuka: Kumakhala ndi kusungunuka kochepa m'madzi koma kumatha kusungunuka mu zosungunulira za organic.

 

Gwiritsani ntchito:

- 2-acetyl-3-methylpyrazine nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati pakupanga mankhwala. Ikhoza kugwiritsidwa ntchito ngati reagent madzi m'thupi, cyclization reagent, kuchepetsa wothandizira, etc. mu kaphatikizidwe organic.

 

Njira:

- 2-acetyl-3-methylpyrazine ikhoza kukonzedwa pochita 2-acetylpyridine ndi methylhydrazine.

- Njira yeniyeni yokonzekera ingapezeke m'mabuku a organic chemical synthesis.

 

Zambiri Zachitetezo:

- 2-Acetyl-3-methylpyrazine ikhoza kukwiyitsa khungu ndi maso ndipo iyenera kutsukidwa ndi madzi ambiri mukangokhudzana.

- Mukamagwiritsa ntchito kapena kugwira, pewani kutulutsa fumbi kapena mpweya. Iyenera kugwiritsiridwa ntchito pamalo olowera mpweya wabwino.

- Posunga, ziyenera kusungidwa m'chidebe chopanda mpweya, kutali ndi magwero a kutentha ndi zinthu zoyaka moto.
