4-Acetylpyridine, tseem hu ua methyl-4-pyridyl ketone, yog cov organic compound nrog cov tshuaj formula C7H7NO thiab molecular hnyav ntawm 121.1366. Nws yog xim tsis muaj xim rau daj ntseg daj kua nrog ib tug pungent tsw. Cov ntsiab lus kub ntawm 4-acetylpyridine yog 212.81 degree, qhov ceev yog 1.061 g / cm³, lub teeb nyem yog 86.96 degree , thiab qhov taw qhia refractive yog 1.529. Nws yog me ntsis soluble hauv dej thiab soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether.
Hais txog cov khoom siv tshuaj lom neeg, 4-acetylpyridine yog cov kua ua kua thiab muaj nyob rau hauv qeb ntawm cov tshuaj lom. Nws tuaj yeem decompose thaum rhuab los tsim cov pa phem nitrogen oxide. Nws yuav tsum tau muab cia rau hauv ib lub ventilated, low-temperature, qhuav warehouse. 4-Acetylpyridine yog incompatible nrog muaj zog oxidants, muaj zog acids, thiab muaj zog txo tus neeg sawv cev.
4-Acetylpyridine feem ntau yog siv hauv cov organic synthesis, kev lag luam tshuaj, thiab kev lag luam roj hmab. Raws li ib qho tseem ceeb nruab nrab ntawm cov tshuaj tua kab synthesis, ib tug series ntawm tshuaj tua kab tsim los ntawm nws muaj cov yam ntxwv ntawm broad spectrum, high efficiency thiab tsawg toxicity, uas yog ib qho tseem ceeb heev rau kev ua liaj ua teb kev loj hlob thiab kev tiv thaiv ecological. Nrog rau kev nce hauv kev thov, kev ua lag luam muaj peev xwm yog dav heev.
Hais txog cov txheej txheem synthesis, 4-acetylpyridine tuaj yeem ua ke los ntawm ntau txoj hauv kev, xws li los ntawm reacting pyridine nrog acetic anhydride nyob rau hauv muaj zinc hmoov, los yog los ntawm reacting pyridine nrog acetic anhydride los tsim diacetyl bipyridine, thiab tom qab cua sov thiab zinc hmoov txo, nws yog muab rho tawm los ntawm hnyav thiab refined los ntawm distillation kom tau ib tug ntshiab cov khoom.
