| Section2 = }} Titanium ethoxide is a chemical compound with the formula Ti4(OCH2CH3)16. It is a colorless solid that is soluble in organic solvents but hydrolyzes readily. It is sold commercially as a colorless solution. Alkoxides of titanium(IV) and zirconium(IV) are used in organic synthesis and materials science. They adopt more complex structures than suggested by their empirical formulas.〔Ram C. Mehrotra, Anirudh Singh "Recent Trends in Metal Alkoxide Chemistry" Progress in Inorganic Chemistry, 1997, Volume 46, p. 239ff. 〕 ==Syntheses== Titanium ethoxide is prepared by treating titanium tetrachloridel halide with ethanol in the presence of an amine: :TiCl4 + 4 EtOH + 4 Et3N → Ti(OEt)4 + 4 Et3NHCl The purity of titanium ethoxide is commonly assayed by proton NMR spectroscopy. Zr(OEt)4 1H NMR (60 MHz, benzene-d6, ppm): 8.64 (triplet, 12H, CH3), 5.73 (quartet, 8H, CH2).〔 Ti(OEt)4 1H NMR (90 MHz, chloroform-d, ppm): 4.36 (quartet, 8H, CH2), 1.27 (triplet, 12H, CH3).〔Integrated Spectral Database System of Organic Compounds, version 2011.
