Okwu mmalite
2-Acetyl-3-ethylpyrazine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke akụrụngwa, ojiji, ụzọ nkwadebe na ozi nchekwa nke ogige ahụ:
Ngwongwo: 2-acetyl-3-ethylpyrazine bụ kristal na-enweghị ụcha siri ike nke nwere usoro heterocyclic nitrogen pụrụ iche. Ọ nwere nkwụsi ike dị elu na enweghị mgbanwe na ụlọ okpomọkụ. Ọ dị mfe soluble na ụfọdụ ihe mgbaze organic na obere soluble na mmiri.
Na-eji: 2-acetyl-3-ethylpyrazine nwere ọtụtụ ihe eji eme ihe na njikọ organic. Enwere ike iji ya dị ka ihe na-akpali akpali maka ọtụtụ mmeghachi omume organic dị mkpa, dị ka carbonylation, oxidation, na amination.
Usoro nkwadebe: Enwere ọtụtụ ụzọ isi kwadebe 2-acetyl-3-ethylpyrazine, a na-enwetakwa usoro a na-ejikarị eme ihe site na mmeghachi omume acetylformamide na 3-ethylpyrazine. Kpọmkwem, acetoformamide na 3-ethylpyrazine na-ebu ụzọ gwakọta, na-ekpo ọkụ n'okpuru ọnọdụ kwesịrị ekwesị, mgbe ahụ, a na-enweta ihe ezubere iche site na crystallization na ịdị ọcha.
Ọ nwere ike ịkpasu anya, akpụkpọ ahụ, na usoro iku ume, yana akụrụngwa nchebe kwesịrị ekwesị dị ka iko, uwe aka, na ihe mkpuchi kwesịrị iyi mgbe ị na-arụ ọrụ. Ọ bụrụ na kọntaktị na mberede ma ọ bụ iku ume nke ogige a, saa ma ọ bụ kpọtụrụ dọkịta ozugbo.
