【摘要】 以ZnAl-TA、MgAl-TA为前驱体,用离子交换法将Waugh结构的杂多阴离子[MnMo9O32]6-嵌入Zn—Al型和Mg—Al型阴离子粘土层间,合成了大层间距的新型层柱状化合物[Zn0.66Al0.34(OH)2]·0.055[Mn1.04Mo9.00O32]·0.01TA·0.5H2O和[Mg0.59Al0.41(OH)2]·0.059[Mn1.02Mo9.00O32]·0.03TA·0.7H2O.通过XFS、XRD、IR和TG-DTA等手段研究了它们的结构和性质,以乙酸与正丁醇的酯化反应为模型反应考察了新型层柱化合物的催化活性.更多还原

【Abstract】 With ZnAl-TA and MgAl-TA as precursors , Waugh structure [MnMo₉O₃₂]^6- was inserted Zn-Al and Mg-Al type anionic clay pillared.Layered double hydroxide pillared by heteropolyoxometales, [Zn_0.66Al_0.34（OH）₂]·0.055[Mn_1.04Mo_9.00O₃₂]·0.01TA·0.5　H₂O　and[Mg_0.59Al_0.41（OH）₂]·0.059[Mn_1.02Mo_9.00O₃₂]·0.03TA·0.7　H₂O have been synthesized by anion exchange. The structuresand properities of the new compounds were studied by XRD,IR,XFS and TG-DTA. Catalytic activities of those new compounds for esterification of acetic acid with n-butanol was also studied.更多还原
