辛烷基四价金属盐［Ｍ（Ｒ－ＯＰＯ＿３）＿２］是一类新型色谱固定相──均相键合相，本文报道了辛烷基磷酸铈（ＣＯＰＰ）的合成，结构及气相色谱性能，元素分析、红外、Ｘ射线粉末衍射分析结果表明：ＣＯＰＰ具有类似于α一磷酸铬的层状结构，重复单元为Ｃ＿Ｈ＿（１７）ＯＰＯ＿３ＣｅＯ＿３ＰＯＣ＿８Ｈ＿（１７），且层间碳链没有弯曲或扭曲现象。热量分析表明ＣＯＰＰ较硅胶键合相有更高的热稳定性。在ＣＯＰＰ上测定了△Ｈ与分子连通指数Ｘ值，并且首次发现了它们之间的良好线性。
Octane tetravalent metal salt [M (R-OPO_3) _2] is a new type of chromatographic stationary phase - homogeneous phase. The synthesis, structure and gas chromatographic performance of octaalkyl-cerium phosphate The results of elemental analysis, IR and X-ray powder diffraction showed that COPP has a layered structure similar to chromium α-phosphate and the repeating unit is C_H_ (17) OPO_3CeO_3POC_8H_ (17). The interlayer carbon chains have no bending or twisting phenomenon. Thermal analysis shows that COPP has higher thermal stability than silica-bonded phase. The △ H and molecular connectivity index X values were determined at COPP and for the first time found a good linearity between them.
