Gabatarwa
3-Acetylpyridine abu ne na halitta. Mai zuwa shine gabatarwa ga wasu kaddarorin, amfani, hanyoyin shiri da bayanan aminci na 3-acetylpyridine:
inganci:
Bayyanar: 3-acetylpyridine ba shi da launi zuwa lu'ulu'u masu launin rawaya ko daskararru.
Solubility: 3-acetylpyridine yana narkewa a cikin kaushi na halitta kamar su alcohols, ethers da ketones, kuma dan kadan mai narkewa cikin ruwa.
Abubuwan Sinadarai: 3-Acetylpyridine wani fili ne mai raunin acidic wanda ke cikin ruwa.
Amfani:
A matsayin sinadari mai haɗaɗɗiyar halitta: 3-acetylpyridine ana yawan amfani dashi a cikin halayen halayen halitta azaman ƙarfi, reagent acylation, da mai kara kuzari.
An yi amfani dashi a cikin haɗin launi: 3-acetylpyridine za a iya amfani dashi a cikin kira na dyes da pigments.
Hanya:
Akwai hanyoyi da yawa don shirya 3-acetylpyridine, kuma ana samun na kowa ta hanyar esterification dauki na stearic anhydride da pyridine. Gabaɗaya, stearic anhydride da pyridine suna amsawa a cikin wani ƙarfi a cikin rabon molar na 1: 1, kuma ana ƙara haɓakar haɓakar acid mai wuce gona da iri yayin aikin, kuma ana aiwatar da halayen esterification na thermodynamically. An samo samfurin 3-acetylpyridine ta hanyar crystallization, tacewa, da bushewa.
Bayanin Tsaro:
3-Acetylpyridine ya kamata a adana kuma a sarrafa shi ta hanyar da za ta guje wa haɗuwa da oxidants don guje wa wuta ko fashewa.
Bi ayyukan aminci na dakin gwaje-gwaje kuma saka kayan kariya masu dacewa kamar safar hannu, tabarau, da riguna yayin amfani da su.
A guji shakar numfashi, ciki, ko tuntuɓar fata da idanu, kuma a yi ƙoƙarin yin aiki a wuri mai cike da iska.
Ya kamata a kula don guje wa ƙura da ɓarna yayin sarrafa 3-acetylpyridine don rage haɗarin inhalation.
