บทคัดย่อ

A much milder, simpler and more straightforward reaction a give to titanium glycolate product was successfully  investigated by the reaction of titanium dioxide, ethylene glycol and triethylenetetramine using the oxide one pot synthesis (OOPS) process. The FT-IR spectrum demonstrates the characteristics of titanium glycolate at 619 and 1080 cm-1 assigned to Ti-0 stretching and C-0-Ti stretching vibrations, respectively. (Blohowiak, et al. 1992) C-solid state NMR spectrum gives two peaks at 75.9 and 79.8 ppm due to the relaxation of the crystalline spirotitanate product. The percentage of carbon and hydrogen from elemental analysis are 28.6 and 4.8, respectively. The thermal analysis study from TGA exhibits only one sharp transition at 340°C, corresponding to the decomposition transition of an organic ligand, and giving a ceramic yield, titanium glycolate, of 46.95% which is close to the theoretical yield of 47.50%. XRD patterns show the morphology change of its pyrolyzed product from anatase to rutile as increasing calcining temperatures from 500°C to 1100°C while at 300°C the amorphous phase is formed.
