Mawu Oyamba
3-Acetylpyridine ndi organic pawiri. Zotsatirazi ndikuyambitsa zina mwazinthu, ntchito, njira zokonzekera ndi chidziwitso chachitetezo cha 3-acetylpyridine:
Ubwino:
Mawonekedwe: 3-acetylpyridine ndi yopanda utoto mpaka makristalo achikasu owala kapena zolimba.
Kusungunuka: 3-acetylpyridine imasungunuka mu zosungunulira za organic monga ma alcohols, ethers ndi ketones, komanso kusungunuka pang'ono m'madzi.
Chemical Properties: 3-Acetylpyridine ndi ofooka acidic pawiri kuti acidic m'madzi.
Gwiritsani ntchito:
Monga organic kaphatikizidwe mankhwala: 3-acetylpyridine amagwiritsidwa ntchito mu organic synthesis zochita monga zosungunulira, acylation reagent, ndi chothandizira.
Amagwiritsidwa ntchito popanga utoto: 3-acetylpyridine angagwiritsidwe ntchito popanga utoto ndi utoto.
Njira:
Pali njira zambiri zokonzekera 3-acetylpyridine, ndipo wamba amatengedwa ndi esterification reaction ya stearic anhydride ndi pyridine. Ambiri, stearic anhydride ndi pyridine anachita mu zosungunulira pa molar chiŵerengero cha 1: 1, ndi owonjezera asidi chothandizira anawonjezera pa anachita, ndi thermodynamically ankalamulira esterification anachita. 3-acetylpyridine mankhwala anapezedwa ndi crystallization, kusefera, ndi kuyanika.
Zambiri Zachitetezo:
3-Acetylpyridine iyenera kusungidwa ndikusamalidwa m'njira yopewa kukhudzana ndi oxidants kuti pasakhale moto kapena kuphulika.
Tsatirani njira zachitetezo cha labotale ndikuvala zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi mikanjo mukamagwiritsa ntchito.
Pewani kutulutsa mpweya, kumeza, kapena kukhudza khungu ndi maso, ndipo yesani kugwirira ntchito pamalo olowera mpweya wabwino.
Chisamaliro chiyenera kutengedwa kuti mupewe fumbi ndi tinthu tating'onoting'ono pogwira 3-acetylpyridine kuti muchepetse chiopsezo chokoka mpweya.
