ABSTRACT

Tin and titanium pentenoate have been prepared from tin(IV) butoxide and titanium (IV) isopropoxide in alcohol and 3-pentenoic acid. Reactions of Sn(OBun)4 and Ti(OPri)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 13C, 1HNMR and FT-IR spectroscopy. 13C{1H}, 1H-NMR and FT-IR spectra showed that 3-pentenoic acid completely reacted with Sn(OBun)4 and Ti(OPri)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 13C, 1H NMR and FT-IR. After hydrolysis, it was seen that no 3-pentenoic acid was released from [Ti(OPri)3(PA)]n and but was released from [Sn(OBun)3(PA)]n under the studied conditions.
