Okwu mmalite
3-Acetylpyridine bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ụfọdụ njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke 3-acetylpyridine:
Ogo:
Ọdịdị: 3-acetylpyridine enweghị agba na kristal edo edo ma ọ bụ ihe siri ike.
Solubility: 3-acetylpyridine bụ soluble na organic solvents dị ka alcohols, ethers na ketones, na ubé soluble na mmiri.
Njirimara kemịkalụ: 3-Acetylpyridine bụ ngwakọta acid na-adịghị ike nke bụ acidic na mmiri.
Jiri:
Dị ka kemịkalụ njikọ organic: 3-acetylpyridine bụ nke a na-ejikarị eme ihe na mmeghachi omume nke organic dị ka ihe mgbaze, acylation reagent, na catalyst.
Ejiri ya mee ihe na ntinye agba: 3-acetylpyridine nwere ike iji mee ihe na ntinye nke agba na pigmenti.
Usoro:
Enwere ọtụtụ ụzọ isi kwadebe 3-acetylpyridine, nke a na-enwetakarị site na mmeghachi omume esterification nke stearic anhydride na pyridine. N'ozuzu, stearic anhydride na pyridine na-emeghachi omume na ihe mgbaze na nha nha nke 1: 1, a na-agbakwunye ihe na-eme ka acid dị elu n'oge mmeghachi omume ahụ, a na-emekwa mmeghachi omume esterification nke thermodynamically. E nwetara ngwaahịa 3-acetylpyridine site na kristal, nzacha, na ihicha.
Ozi nchekwa:
3-Acetylpyridine kwesịrị ịchekwa ma mee ya n'ụzọ na-ezere kọntaktị na oxidants iji zere ọkụ ma ọ bụ mgbawa.
Soro omume nchekwa ụlọ nyocha ma yiri akụrụngwa nchedo kwesịrị ekwesị dị ka uwe, enyo na uwe mgbe ị na-eji.
Zere iku ume, nri, ma ọ bụ kọntaktị na akpụkpọ ahụ na anya, ma gbalịa ịwa ahụ n'ebe ikuku na-ekpo ọkụ.
Ekwesịrị iji nlezianya zere uzuzu na ụmụ irighiri ihe mgbe ị na-ejikwa 3-acetylpyridine iji belata ihe ize ndụ nke iku ume.
