cze	Benzyl substituované acetylacetonátové komplexy vanadu: příprava, struktura a katalytické vlastnosti	Nové katalyzátory na bázi vanadu, které urychlují zasychání alkydových pryskyřic, byly připraveny a charakterizovány pomocí infračervené spektroskopie, elektronové paramagnetické rezonance a RTG difrakční analýzy. Jejich katalytická aktivita byla studována na 4 alkydových pryskyřicích.	vanad; katalytická aktivita; alkyd
eng	Benzyl substituted oxidovanadium(IV) pentane-2,4-dionates: Synthesis, structure and drying properties	New catalysts improving drying of alkyd resins were synthetized and characterized by infrared spectroscopy and electron paramagnetic resonance. Their structure was determined by X-ray structure analysis. The catalytic performance of these oxidovanadium(IV) pentane-2,4-dionate complexes bearing benzyl substituents were studied on four different alkyd resins modified with soybean oil. Results obtained from standard mechanical tests revealed high acceleration of autoxidation process resulting in short total dry times. Evaluation of cured films by electron paramagnetic resonance enabled to follow the active oxidovanadium species, which is generated upon drying process.
