摘要
采用浊度法研究了Ｐｂ－Ｔｉ复合醇盐的水解聚结过程。发现该过程随水量和醇盐浓度的增大而加快，碱（ＮＨ＿４ＯＨ）能够大大促进水解聚结反应，酸（ＨＯＡｃ）则在低浓度时起促进作用高浓度时起抑制作用。根据醇盐水解聚结的反应机理对以上结果作了解释。
The hydrolysis-condensation process of Pb-Ti complex alkoxide has been studiedby turbidimetry.It was found that increase in both the amount of water and alkoxide concen-tration accelerated the hydrolysis-condensation reaction. NH_4OH greatly promoted the hy-drolysis-condensation reaction,while HOAc showed a promotion effect at lower acid concen-tration,but a suppression effect at higher acid concentration.The results have been ex-plained in terms of hydrolysis-condensation reaction of alkoxide.
