Khoom Description
Cov tshuaj sib xyaw ua ke rau CAS 19372 - 44 - 2 yog Calcium acetylacetonate (CAA), nrog rau cov tshuaj formula C₁₀H₁₄CaO₄ thiab molecular hnyav ntawm 238.29 g / mol. Nws zoo nkaus li cov hmoov dawb nrog cov ntxhiab tsw me ntsis, insoluble hauv dej, ethanol, thiab benzene, tab sis soluble hauv methanol.
Calcium acetylacetonate muaj qhov melting point ntawm 270℃thiab pom zoo thermal stability ntawm qhov kub thiab txias. Raws li ib tug - diketone hlau complex, nws tsim ib tug ruaj khov qauv los ntawm intramolecular kev sib koom tes, ua kom pom kev siab siab rau lub teeb, tshav kub, thiab oxidative ib puag ncig.

siv
Raws li cov yas stabilizer, Calcium acetylacetonate ua haujlwm zoo li ib puag ncig tus phooj ywg kub stabilizer rau polyvinyl chloride (PVC). Nws hloov cov hmoov txhuas - uas muaj cov khoom siv ntxiv thiab, thaum ua ke nrog calcium zinc stabilizers, ua rau lub sijhawm Congo liab (qhov taw qhia thermal stability) ntawm PVC. Nws kuj muab lub teeb ruaj khov thiab cov teebmeem antioxidant, ua rau nws tsim nyog rau kev siv xws li cov kav dej thiab cov phaj.
Hauv cov ntawv thov catalyst, nws cov chaw ua haujlwm hlau txhawb cov tshuaj tiv thaiv organic xws li esterification thiab ntxiv, ua rau nws siv dav hauv kev sib txuas ntawm cov resins, coatings, thiab tshuaj intermediates.
