多氧代铝酸盐的改性及油凝性

Modification and Gelation Properties of Poly-oxo-aluminum Salts

研究采用不同碳链长度以及结构的烷基酸对多氧代铝盐进行化学改性的可能性以及采用异辛酸进行改性的反应条件，对改性有机酸的结构、反应温度、时间等进行了系统研究，并利用红外光谱、差热分析探讨了改性后的多氧代铝盐与改性前的性质和结构差别的原因。异辛酸改性后的多氧代铝酸盐具有良好的与煤油形成凝胶的能力，并且具有不易水解，便于保存的优点。

Poly-oxo-aluminum salts modified with organic acids have been prepared.The reaction tem-perature and time,ratio of organic acid to poly-oxo-aluminum salt,and difference in physical andchemical properties between modified and unmodified salts have been studied.The experiment re-sults show that due to replacement of organic acid,modified poly-oxo-aluminum salt has a core-shell structure,and is resistant to hydrolysis.
