A new efficient method for the synthesis of extended micro-and nano-sized crystals (whiskers, fibers) of titanium glycolate Ti(OCH(2)CH(2)O)(2) has been suggested. The method implies the reaction of hydrated titanium dioxide with ethylene glycol on heating in air. Thermolysis of Ti(OCH(2)CH(2)O)(2) in air gives titanium dioxide as anatase (400-500 degrees C) and rutile (T > 700 degrees C), the morphology of titanium glycolate crystals being inherited by the oxide. The pseudocrystals of the thermolysis product in an inert gas medium (T = 500-950 degrees C) represent aglomeration of nano-sized titanium dioxide particles and amorphous carbon. At temperatures up to 1300 degrees C, the formation of the TiO(2-x) C (x) phase with a rutile structure is probable. In a wet air environment, titanium glycolate is partially hydrolyzed to give TiO(x)(OCH(2)CH(2)O)(2-2x) (OH)(2x) center dot xH(2)O (0 <= x <= 1) and on keeping in water at room temperature, ethylene glycol is completely displaced from the crystals. This process is also not accompanied by changes in the particle morphology.
