Mawu Oyamba
2-Methoxypyrimidine ndi organic compound. Ndi woyera crystalline wolimba ndi fungo lachilendo. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-methoxypyrazine:
Ubwino:
- Maonekedwe: Makristalo oyera olimba
- Kusungunuka: Kusungunuka mu mowa, ethers ndi ester solvents, kusungunuka pang'ono m'madzi
Gwiritsani ntchito:
- 2-Methoxypyrazine itha kugwiritsidwanso ntchito pamakampani opanga utoto kuti apange utoto wachilengedwe.
Njira:
- 2-Methoxypyrazine nthawi zambiri imapezeka ndi zomwe 2-hydroxypyrazine ndi methanol. 2-Hydroxypyrazine imachitidwa ndi sodium formate kapena sodium carbonate kuti ipange mchere wofananira wa sodium, ndiyeno methanol owonjezera amawonjezedwa kuti achite zomwe zimachitika pa kutentha koyenera komanso nthawi yochitira. 2-methoxypyrazine mankhwala anapezedwa ndi acidic mankhwala, crystallization, kuyanika ndi njira zina.
Zambiri Zachitetezo:
- 2-Methoxypyrazine imakwiyitsa ndipo iyenera kupewedwa kuti isakhudze khungu ndi maso.
- Samalani mukamagwiritsa ntchito, monga kuvala zoteteza maso ndi kupuma.
- Pewani kutulutsa mpweya, kumeza, kapena kukhudzana ndi fumbi, mpweya, kapena njira zapawiri.
- Onetsetsani kuti mpweya wabwino ukugwira ntchito.
- Sungani 2-methoxypyrazine pamalo owuma, ozizira, opanda mpweya wabwino kutali ndi moto ndi ma oxidants.
