Özet

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-13-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.
