1. Khoom: Acetylacetone yog cov kua uas tsis muaj xim lossis daj me ntsis flammable. Boiling point yog 135-137 ℃, flash point yog 34 ℃, melting point -23 ℃. Tus txheeb ze ntom ntom yog 0.976, thiab qhov ntsuas qhov taw qhia yog n20D1.4512. 1g ntawm acetylacetone yog soluble hauv 8g dej, thiab yog miscible nrog ethanol, benzene, chloroform, ether, acetone thiab glacial acetic acid, thiab decomposes rau hauv acetone thiab acetic acid nyob rau hauv lye. Nws yog ib qho yooj yim los ua combustion thaum raug kub siab, qhib nplaim taws thiab muaj zog oxidants. Nws tsis ruaj khov hauv dej thiab yooj yim hydrolyzed rau hauv acetic acid thiab acetone.
2. Mob toxicity. Nws tuaj yeem ua rau tawv nqaij thiab mucous daim nyias nyias. Thaum tib neeg lub cev nyob ntev dua (150 ~ 300) * 10-6, nws tuaj yeem raug mob. Cov tsos mob xws li mob taub hau, xeev siab, ntuav, kiv taub hau, thiab dullness yuav tshwm sim, tab sis nws yuav raug cuam tshuam thaum lub concentration yog 75 * 10-6. Tsis muaj kev phom sij. Kev tsim khoom yuav tsum tau siv lub tshuab nqus tsev sealing. Qhov cua yuav tsum tau ntxiv dag zog rau ntawm qhov chaw ua haujlwm kom txo qis khiav, xau, xau thiab xau. Thaum muaj tshuaj lom, tawm ntawm qhov chaw kom sai li sai tau thiab ua pa tshiab. Cov neeg ua haujlwm yuav tsum hnav cov iav tiv thaiv thiab ua haujlwm tshuaj xyuas kab mob ua haujlwm tsis tu ncua.
