Hoʻolauna
ʻO 2-Acetyl-3-ethylpyrazine kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka pūhui:
Nā waiwai: 2-acetyl-3-ethylpyrazine he paʻa kala kala ʻole me kahi ʻano heterocyclic nitrogen kūikawā. Loaʻa iā ia ke kūpaʻa kiʻekiʻe a me ka non-volatility i ka lumi wela. He maʻalahi hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe organik a emi ʻole i ka wai.
Hoʻohana: 2-acetyl-3-ethylpyrazine ka nui o ka hoʻohana ʻana i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he catalyst maikaʻi no nā hopena kūlohelohe koʻikoʻi, e like me ka carbonylation, oxidation, a me ka amination.
Kaʻina hoʻomākaukau: Nui nā ala e hoʻomākaukau ai i ka 2-acetyl-3-ethylpyrazine, a loaʻa ke ʻano hana maʻamau ma ka hana ʻana i ka acetylformamide a me 3-ethylpyrazine. ʻO keʻano, ua hui muaʻia ka acetoformamide a me ka 3-ethylpyrazine, hoʻomehanaʻia ma lalo o nā kūlana kūpono, a laila loaʻa ka huahana i hoʻopaʻaʻia e ka crystallization a me ka hoʻomaʻemaʻe.
Hiki ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōnaehana hanu, a pono e hoʻohana ʻia nā mea pale kūpono e like me nā aniani, nā mīkina lima, a me nā pale pale i ka wā e hana ai. Inā loaʻa ka pilikia a i ʻole ka inhalation o kēia pūhui, holoi a nīnau koke i ke kauka.
