1. Katundu: Acetylacetone ndi madzi opanda mtundu kapena achikasu pang'ono omwe amatha kuyaka.Malo otentha ndi 135-137 ℃, flash point ndi 34 ℃, malo osungunuka ndi -23 ℃.Kuchulukana kwachibale ndi 0.976, ndipo refractive index ndi n20D1.4512.1g ya acetylacetone imasungunuka mu 8g ya madzi, ndipo imasakanikirana ndi ethanol, benzene, chloroform, ether, acetone ndi glacial acetic acid, ndipo imawola kukhala acetone ndi acetic acid mu lye.Ndikosavuta kuyambitsa kuyaka mukakumana ndi kutentha kwakukulu, malawi otseguka komanso ma oxidants amphamvu.Imakhala yosakhazikika m'madzi ndipo imasinthidwa mosavuta kukhala acetic acid ndi acetone.
2. Kawopsedwe wapakatikati.Ikhoza kukhumudwitsa khungu ndi mucous nembanemba.Thupi la munthu likakhala kwa nthawi yayitali pansi pa (150~300)*10-6, likhoza kuvulazidwa.Zizindikiro monga mutu, nseru, kusanza, chizungulire, ndi kufooka zidzawoneka, koma zidzakhudzidwa pamene ndende ndi 75 * 10-6.Palibe ngozi.Chopangacho chiyenera kukhala ndi chipangizo chosindikizira cha vacuum.Mpweya wabwino uyenera kulimbikitsidwa pamalo opangira opaleshoni kuti achepetse kuthamanga, kutsika, kudontha komanso kutayikira.Pakakhala poyizoni, chokani pamalopo mwachangu ndikupuma mpweya wabwino.Ogwira ntchito ayenera kuvala zida zodzitchinjiriza ndikuwunika pafupipafupi matenda omwe ali pantchito.
