制备了亚磷酸苯膦酸锆Ｚｒ（Ｃ６Ｈ５ＰＯ３）２－ｘ（ＨＰＯ３）ｘ·ｎＨ２Ｏ（Ｐｉ－ＺｒＰＰ）和磷酸磺酸基苯膦酸锆Ｚｒ（ＨＳＯ３Ｃ６Ｈ４ＰＯ３）２－ｘ（ＨＰＯ４）ｘ·ｎＨ２Ｏ（ＺｒＳＰ）。Ｘ射线粉末衍射法证明，它们都具有典型的层状结构。如在不同条件下制得Ｐｉ－ＺｒＰＰ的层间距有两种，分别为１．５１ｎｍ和１．０６ｎｍ左右，ＺｒＳＰ的层间距为１．６１ｎｍ。用红外光谱、元素分析、热失重分析法研究了Ｐｉ－ＺｒＰＰ和ＺｒＰＰ的结构特性。考察了Ｐｉ－ＺｒＰＰ和ＺｒＳＰ催化无水乙醇和环氧丙烷反应合成窄分布醇醚的性能
(ZrO 3) x · nH 2 O (Pi-ZrPP) and Zr (HSO 3 C 6 H 4 PO 3) 2-x (HPO 4) x · nH 2 O ). X-ray powder diffraction proved that they all have a typical layered structure. For example, there are two kinds of interlayer spacing of Pi-ZrPP obtained under different conditions, namely 1.51 nm and 1.06 nm, respectively, and the interlayer spacing of ZrSP is 1.61 nm. The structural properties of Pi-ZrPP and ZrPP were studied by IR, elemental analysis and TG-IR analysis. The effects of Pi-ZrPP and ZrSP on the synthesis of narrow-profile alcohol ethers via the reaction of absolute ethanol and propylene oxide
