硬脂酸铝/芳烃凝胶的形成与破坏

Formation and Degradation for the Aluminum Stear ate/Aromatic Hydrocarbon Gel

本工作研究了硬脂酸铝/苯和硬脂酸铝/甲苯体系的粘度随时间的变化。结果表明这两种体系逐渐形成粘度较大的凝胶后,凝胶网络随即又开始一个破胶过程。添加有配位倾向的含羟基的化合物会加快破胶过程。

The viscosity changes with time of both the aluminum stearate/benzene system and the aluminum stearate/toluene system have been studied. The obtained results indicate that degradation of gel net will begin just after the formation of the gel with high viscosity gradually developed in the processes of the two systems.Addition of the compounds with hydroxyl groups and a tendency of coordination will accelerate the degradation.
