Oja Açik, J. Madarász, M. Krunks, K. Tõnsuaadu, D. Janke, G. Pokol, L. Niinistö] Thermal decomposition of precursor xerogels for TiO2, obtained by gelling of acetylacetonate-modified titanium(IV) tetraisopropoxide (prepared at Ti-alkoxide:acetylacetone molar ratios of 1:1 (Ti-1) and 1:2 (Ti-2)) in boiling 2-methoxyethanol, was monitored by simultaneous TG/DTA/EGA-MS and EGA-FTIR measurements. Thermal degradation processes of Ti-1 and Ti-2 in the temperature range of 30-700°C consist of six mass loss steps, the total mass loss being 46.3% and 54.4%, respectively. EGA by FTIR and MS revealed release of H2O below 120°C; followed by evolution of acetone and acetic acid between approximately 100 and 320°C, and that of CO2 up to 560°C. Acetylacetone is evolved to a significant extent from sample Ti-2 at 120-200°C.
