Mawu Oyamba
2-Ethyl-3-methylpyrazine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: 2-ethyl-3-methylpyrazine ili mumadzi opanda mtundu kapena mawonekedwe olimba a crystalline.
- Kusungunuka: Kumakhala ndi kusungunuka kochepa m'madzi, koma kumatha kusungunuka mu zosungunulira za organic.
- Kukhazikika: Ndi chinthu chokhazikika, koma kukhudzana ndi ma okosijeni amphamvu ndi ma asidi amphamvu kuyenera kupewedwa.
Gwiritsani ntchito:
- 2-Ethyl-3-methylpyrazine ndi reagent yomwe imagwiritsidwa ntchito kwambiri ndipo imagwiritsidwanso ntchito ngati wapakatikati pakupanga mankhwala.
Njira:
2-Ethyl-3-methylpyrazine ikhoza kukonzedwa ndi njira zotsatirazi:
- Ethyl bromide imayendetsedwa koyamba ndi pyrazine kuti ipange 2-ethylpyrazine pansi pamikhalidwe yamchere.
- Pambuyo pake, 2-ethylpyrazine imayendetsedwa ndi methyl bromide kuti ipereke 2-ethyl-3-methylpyrazine yomaliza.
Zambiri Zachitetezo:
- 2-Ethyl-3-methylpyrazine nthawi zambiri imatengedwa kuti ndi ya poizoni yochepa, koma ndondomeko zoyenera zotetezera ziyenera kutsatiridwa.
- Pewani kutulutsa mpweya, kukhudza khungu ndi maso, komanso kuvala zida zodzitetezera monga magolovesi, magalasi, ndi zishango zakumaso.
- Posunga ndikugwira, sungani kutali ndi komwe mungayatseko ndi zinthu zoziziritsa kukhosi kuti mupewe ngozi ya moto ndi kuphulika.
- Onaninso zolemba zotetezedwa ndi mapepala otetezedwa operekedwa ndi ogulitsa kuti mudziwe zambiri komanso zolondola zachitetezo.
