摘要：
A variety of titanate gels were prepared from lead acetate and titanium isopropoxide in methoxyethanol. In the present study, 1H and 13C Fourier transform‐nuclear magnetic resonance and mass spectroscopic techniques were used to identify the structure of the lead and titanium precursors formed from lead acetate and titanium isopropoxide, respectively, when refluxed in methoxyethanol. The lead and titanium precursors were determined to be Pb(OOCCH3) (OC2H4OCH3). xH2O, where x < 0.5, and Ti2(OC2H4OCH3)8, respectively. Similar spectroscopic procedures were applied to identify the lead titanium complex formed from the reaction between lead and titanium precursors. Copyright © 1990, Wiley Blackwell.
