Özet
In this work, alcoholysis reactions of aluminium-sec-butoxide, Al(OBu-s)(3), with 2-ethoxyethanol (EtOCH2CH2OH) and 2-butoxyethanol (BuOCH2CH2OH), complexation reactions of Al(OBu-s)(3) and of alcohol-modified Al(OBu-s)(3) with methacrylic acid (MAC) and ethyl acetoacetate (EAAH), and the hydrolysis reactions of Al(OBu-s)(3) and modified Al(OBu-s)(3) are studied in some detail. Alcoholysis reactions of Al(OBu-s)(3) were performed with different mole ratios of 2-ethoxyethanol and 2-butoxyethanol at room temperature and combining ratios were found to be 1:3 [Al(OBu-s)(3):alcohol] by H-1 NMR analyses. Al(OBu-s)(3) and alcohol-modified Al(OBu-s)(3) were reacted at room temperature with equimolar amounts of methacrylic acid and ethyl acetoacetate and the products were characterized by H-1 NMR, GC, FT-IR and elemental analyses. Hydrolysis-condensation reactions of the various compounds thus formed were studied in detail and the products were characterized by gas chromatography, Karl Fisher coulometric titrations, thermal analysis and FT-IR.
