R—磷钼杂多酸盐的合成和催化性能的表征

本文叙述了Ｒ－磷钼酸盐的年鉴轩及其催化性能的表征。利用气相色谱法和红外光谱－程序升温脱附法（ＦＴＩＲ－ＴＰＤ），测定了不同制备条件下，Ｒ－磷钼酸盐的固体酸性质（酸量、酸类型和酸强度），结果表明，当Ｒ含量不同，其固体酸性质也不同，通过控制Ｒ含量可能调节Ｒ－磷钼酸的固体酸性质。利用Ｒ－磷钙酸盐作为固体酸催化剂合成邻苯二甲酸二辛酯（ＤＯＰ）的酯化反应表明，当Ｒ－磷钙酸盐的表面呈Ｌ酸较大时，酯化率就较高，

SYNTHESIS OF R-PHOSPHOMOLYBDIC ACID SALTS AND ITS CATALYTIC CHARACTERIZATION OF PSEUDO HOMOGENEOUS

This paper reported the preparation of R-Phosphomolybdic acid salts (R-HPM) and its cataly-tie characterization of pseudo homogeneous. Determining the property of acid of pseudo homogeneous (acid amount, acid strength and acid type) for R-HPM in vary preparing condition with Gas Chromatography and infrared Spectra-Temperature Program Desorption (FTIR-TPD).The results were indicated the different properties of acid for vary R-HPM, when the vary R-content in R-HPM possibly, can adjust the acid of R-HPM during controlling in process of R-HPM.The esterification reaction for synthesis the Dioctyl Phthalate (DOP) with catalyst R-HPM was confirmed the results, which conformed with determining method, while the R-HPM was showed up an excellent new catalyst for synthesis DOP.
