Acetylacetone kuj tseem siv tau ua ib qho catalyst rau kev tawg roj av, hydrogenation thiab carbonylation reactions, thiab ib qho oxidation accelerator rau oxygen. Nws tuaj yeem siv los tshem tawm cov hlau oxides hauv cov khoom khov thiab kho cov polypropylene catalysts. Hauv cov tebchaws European thiab Asmeskas, ntau dua 50% yog siv rau hauv cov tshuaj tua kab mob tsiaj txhu thiab cov khoom noj pub.
5. Ntxiv rau cov khoom siv ntawm cov cawv thiab ketones, nws kuj qhia txog xim liab tsaus nrog ferric chloride thiab tsim cov chelates nrog ntau cov ntsev hlau. Los ntawm acetic anhydride lossis acetyl chloride thiab acetone condensation, lossis los ntawm cov tshuaj tiv thaiv ntawm acetone thiab ketene tau txais. Chemicalbook siv los ua cov hlau extractant los cais cov trivalent thiab tetravalent ions, xim thiab kua mem qhuav, tshuaj tua kab, tshuaj tua kab, fungicides, cov kuab tshuaj rau cov polymers siab, reagents rau kev txiav txim siab ntawm thallium, hlau, fluorine, thiab organic synthesis intermediates.
6. Cov tshuaj chelators hloov pauv hlau. Kev txiav txim siab xim ntawm hlau thiab fluorine, thiab kev txiav txim siab ntawm thallium nyob rau hauv qhov muaj carbon disulfide.
