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.
