Nhanganyaya
2-Acetyl-3-ethylpyrazine inhengo yemuviri. Inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomboni:
Properties: 2-acetyl-3-ethylpyrazine is a colorless crystalline solid ine yakakosha nitrogen heterocyclic structure. Iine kugadzikana kwepamusoro uye kusina-volatility pakupisa kwekamuri. Inonyungudika nyore mune mamwe organic solvents uye isinganyanyi kunyungudika mumvura.
Zvishandiso: 2-acetyl-3-ethylpyrazine ine huwandu hwakawanda hwekushandisa mune organic synthesis. Inogona kushandiswa sechinhu chinobatsira chezvakawanda zvakakosha organic reactions, senge carbonylation, oxidation, uye amination.
Kugadzirira nzira: Kune nzira dzakawanda dzekugadzirira 2-acetyl-3-ethylpyrazine, uye nzira inowanzoshandiswa inowanikwa nekuita acetylformamide uye 3-ethylpyrazine. Kunyanya, acetoformamide uye 3-ethylpyrazine inotanga kusanganiswa, inopisa pasi pemamiriro akakodzera, uye ipapo chinangwa chekugadzirwa chinowanikwa nekristalllization uye kucheneswa.
Zvinogona kutsamwisa maziso, ganda, uye hurongwa hwekufema, uye midziyo yekudzivirira yakakodzera semagirazi, magirovhosi, uye masks ekudzivirira inofanira kupfekwa kana uchishanda. Kana wasangana netsaona kana kufemerwa nekomboni iyi, geza kana kubvunza chiremba nekukasika.
