Nhanganyaya
3-Acetylpyridine inhengo yemuviri. Izvi zvinotevera sumo kune zvimwe zvezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye3-acetylpyridine:
Hunhu:
Kuonekwa: 3-acetylpyridine haina ruvara kune yakavhenekera yero makristasi kana yakasimba.
Solubility: 3-acetylpyridine inonyungudika mu organic solvents senge doro, ethers uye ketones, uye zvishoma soluble mumvura.
Chemical Properties: 3-Acetylpyridine isimbi isina kusimba acidic iyo ine acidic mumvura.
Shandisa:
Sekemikari yakasanganiswa yemakemikari: 3-acetylpyridine inowanzoshandiswa mune organic synthesis reactions se solvent, acylation reagent, uye catalyst.
Inoshandiswa mudhayi synthesis: 3-acetylpyridine inogona kushandiswa mukugadzirwa kwedhayi uye pigment.
Nzira:
Kune nzira dzakawanda dzekugadzira 3-acetylpyridine, uye iyo yakajairika inowanikwa ne esterification reaction ye stearic anhydride uye pyridine. Kazhinji, stearic anhydride uye pyridine inoitwa musolvent pane imwe molar ratio ye1: 1, uye yakawandisa acid catalyst inowedzerwa panguva yekuita, uye thermodynamically controlled esterification reaction inoitwa. Iyo 3-acetylpyridine chigadzirwa chakawanikwa necrystallization, filtration, uye kuomesa.
Zvekuchengetedza
3-Acetylpyridine inofanirwa kuchengetwa uye kubatwa nenzira inodzivirira kusangana neoxidants kudzivirira moto kana kuputika.
Tevedza maitiro ekuchengetedza murabhoritari uye pfeka midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi uye magauni paunenge uchishandisa.
Dzivisa kufema, kunwa, kana kubata neganda nemaziso, uye edza kushanda munzvimbo ine mhepo yakanaka.
Kuchengetedza kunofanira kutorwa kudzivirira guruva uye zvimedu paunenge uchibata 3-acetylpyridine kuderedza njodzi yekufema.
