Spectroscopic Investigation on the Reactions of Tin and Titanium Alkoxides with 3-Pentenoic Acid

چکیده
Tin and titanium pentenoate have been prepared from tin(IV) butoxide and titanium (IV) isopropoxide in alcohol and 3-pentenoic acid. Reactions of Sn(OBu n )4 and Ti(OPr i )4 with 3-pentenoic acid in 1:1 molar ratio were studied in butanol and propanol solution at room temperature by sol-gel process. The complexations were investigated by 13 C, 1 HNMR and FT-IR spectroscopy. 13 C{ 1 H}, 1 H-NMR and FT-IR spectra showed that 3-pentenoic acid completely reacted with Sn(OBu n )4 and Ti(OPr i )4. These new products were hydrolyzed by water in ratio of 1:4 [M(OR)4 /H2O, M: Sn, Ti, R: butyl and isopropyl]. The stability of hydrolyzed products was investigated by 13 C, 1 H NMR and FT-IR. After hydrolysis, it was seen that no 3-pentenoic acid was released from [Ti(OPr i )3(PA)]n and but was released from [Sn(OBu n )3(PA)]n under the studied conditions.

Complexation reactions of titanium tetraethoxide [Ti(OEt)4] and titanium tetra-n-butoxide [Ti(OBu )4] with 3-pentenoic acid (PA) and allylacetoacetate (AAA), in a 1 : 1M ratio, were studied in ethanol solution at room temperature. C-NMR and FTIR spectra showed that all PA and AAA completely reacted with both titanium alkoxides. Hydridosilane compounds such as triethoxysilane and triethylsilane ...
متن کاملInvestigation of the electrical properties and corrosion resistance of TiN coating deposited by reactive sputtering on the titanium bipolar plate, used in polymeric fuel cell
The effect of titanium nitride film on the properties of titanium bipolar plates used in polymeric fuel cell was investigated in this research. TiN coatings was deposited on the Ti-grade 1 substrate by using DC-sputtering method. Pure titanium was used as target and coating deposition was done in argon and nitrogen atmosphere. Different TiN thickness was developed by changing sputtering time. T...

Combination of sol-gel and hydrothermal routes in the metal alkoxide binary system of Al(OR)3-Ti(OR)4 (R= -CH(CH3)2 or -CH2CH2OCH3) were investigated to prepare single phase aluminum titanate (tialite). The effects of various parameters, such as hydrothermal processing temperature, solvent polarity and the type of alkoxide precursor, in phase development of the product powders have been investi...
متن کاملSynthesis of a novel polyester building block from pentoses by tin-containing silicates
We report here the direct formation of the new chemical product trans-2,5-dihydroxy-3-pentenoic acid methyl ester from pentoses using tin-containing silicates as catalysts. The product is formed under alkali-free conditions in methanol at temperatures in the range 140–180 C. The highest yields are found using Sn-Beta as the catalyst. Under optimised conditions, a yield of 33% is achieved. Purif...

A new synthesis of a-hydroxycarboxylates and 2-hydroxybenzoates based on the reaction of acetonides of a-hydroxycarboxylic acids and 2-hydroxybenzoic acid with sodium alkoxides in the corresponding alcohols as solvent is described. In general, decreasing the steric hindrance of the reactants and increasing the boiling points of alcohols increased the yiel...
