Properties of titanium glykolates as precursors for the synthesis of titanium dioxide

The reactions of the formation of monosubstituted titanium ethylene, diethylene, and triethylene glycolates based on the interaction of glycols with tetrabutoxytitanium in solutions were investigated. It was shown that ethylene glycol predominantly forms cyclic structures: diethylene glycol, a mixture of cyclic and linear structures, and triethylene glycol, mainly linear structures. The comparative analysis of the reaction products showed that the most promising precursor for the synthesis of TiO2 is a titanium compound based on triethylene glycol. © 2010 Pleiades Publishing, Ltd

Tetrabutoxytitanium adduct formation in esterification reactions

Different mechanisms of the catalytic action of tetrabutoxytitanium in esterification and transesterification reactions are analyzed. New evidence is obtained in favor of the nonionic mechanism of ester formation catalysis by glycol-tetrabutoxytitanium adducts in esterification reactions. © 2009 Pleiades Publishing, Ltd
