Okwu mmalite
4-Ethylpyridine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke 4-ethylpyridine:
Ogo:
- Ọdịdị: mmiri mmiri na-enweghị agba ma ọ bụ kristal siri ike.
- Solubility: Soluble n'ọtụtụ ihe mgbaze organic, enweghị ike ime na mmiri.
Jiri:
- Dị ka ihe mgbaze: 4-ethylpyridine nwere ezigbo solubility ma na-ejikarị eme ihe dị ka ihe mgbaze ma ọ bụ mmeghachi omume mmeghachi omume, karịsịa na njikọ organic, nke nwere ike ịkwalite ọganihu nke mmeghachi omume.
- Catalyst: 4-ethylpyridine nwekwara ike iji dị ka ihe na-akpali akpali maka ụfọdụ mmeghachi omume organic, dị ka mmeghachi omume Grignard reagent na mmeghachi omume hydrogenation.
Usoro:
- 4-Ethylpyridine nwere ike ịkwado site na mmeghachi omume nke 2-ethylpyridine na ethyl acetate, na-emekarị n'okpuru ọnọdụ alkaline.
Ozi nchekwa:
- 4-Ethylpyridine na-akpasu iwe ma nwee ike ịkpasu anya, akpụkpọ ahụ, na akụkụ iku ume. Yiri ngwa nchebe kwesịrị ekwesị mgbe a na-ejikwa ya ma zere ịkpọtụrụ akpụkpọ ahụ, anya, ma ọ bụ ikuku ikuku.
- Mgbe ị na-eji ma ọ bụ na-echekwa, debe 4-ethylpyridine pụọ na oke okpomọkụ na ọkụ mepere emepe.
- Mgbe a na-ekpofu ihe mkpofu, ọ dị mkpa ịkwanye ya dị ka iwu na iwu obodo siri dị iji zere mmetọ gburugburu ebe obibi.
