以钛酸四丁酯为原料，采用溶胶－ 凝胶法制备 Ｔｉ Ｏ２ 凝胶，并通过测量体系吸光度研究体系中各组分配比等因素对凝胶反应的影响规律，并由此建立反应动力学模型，求得相应的反应速率常数及表观活化能．通过对反应动力学规律的分析提出了 Ｔｉ Ｏ２ 凝胶形成的动力学机理，并验证所得的反应动力学模型
The tetrabutyl titanate was used as raw material to prepare Ti O2 gel by sol-gel method. The influence of various factors such as the ratio of the components in the system on the gel reaction was measured by measuring the absorbance of the system, and the reaction kinetics Model, get the corresponding reaction rate constant and apparent activation energy. Based on the analysis of the reaction kinetics, the kinetic mechanism of the formation of Ti O2 gel was proposed and the reaction kinetics model
