Solvent Effect on Complexation of Titanium Tetraethoxide with Allylacetoacetate
نویسنده
چکیده
The effect of the solvent butanol on the complexation reaction of allylacetoacetate (AAA) with titanium tetraethoxide. (Ti(OEt)4) in molar ratio Ti(OEt)4:AAA = 1:1 was investigated by C-NMR, FT-IR spectroscopy and elemental analysis. The investigation shows that some ethoxy groups that are attached to the titanium are substituted with butoxy groups. The hydrolytic stability of the allylacetoacetate–Ti complex in a molar ratio Ti(OEt)4:H2O = 1:4 was also characterized by spectroscopic techniques and elemental analysis. The result of this characterization shows that almost 20% of the AAA and some ethoxy groups are released from the hydrolyzed product.
