Pentanoic anhydride (tseem hu ua valeric anhydride) yog cov organic compound nrog cov tshuaj formula C10H18O3, molecular hnyav ntawm 186.25, thiab CAS naj npawb ntawm 2082-59-9. Nyob rau hauv chav tsev kub, nws zoo nkaus li tsis muaj xim rau daj pob tshab kua. Nws muaj qhov melting point ntawm -56℃(lit.), boiling point ntawm 227.8 ± 8.0℃(ntawm tus qauv siab), ib tug ceev ntawm 0.944 g / mL (ntawm 25 degree), ib tug refractive index ntawm 1.421 (ntawm 20 degree), thiab ib tug flash point ntawm 101.1℃(kaw taw tes). Nws txoj cai thauj phom sij yog UN 3265 8/PG 3.
Cov tshuaj no yog siv nyob rau hauv chemical synthesis, raws li ib tug raw khoom rau pharmaceuticals, thiab raws li ib tug intermediate nyob rau hauv biopharmaceutical manufacturing. Nws tuaj yeem raug tsim los ntawm lub cev qhuav dej ntawm n-pentanoic acid lossis los ntawm cov tshuaj tiv thaiv nrog n-pentanoyl chloride; nws yuav tsum tau muab cia rau hauv ib qho inert gas cua kom tsis txhob decomposition los ntawm noo noo.
