项目摘要

Synthesis of aluminomethylphosphonate membranes on a porous alumina substrate was attempted by using a hydrothermal method and steam-assisted conversion method. When pseudo-boehmite, methylphosphonic acid, water and t-butyl alcohol were mixed, part of the mixture solution was sucked into the substrate, and the substrate was dipped in the solution, followed by hydrothermal treatment in an autoclave at 160℃, AlMepO-β was crystallized to form a membrane-like aggregates on the substrate probably as a result of composite formation inside the substrate. When the -same mixture solution was sucked into the substrate, and the substrate was dried, followed by steaming in an autoclave, AlMepO-α membrane 40μm thick was obtained where crystallites were grown so as to closely contact on and in the substrate. However, the single gas permeation experiments of oxygen, air and hydrogen gas revealed negligible differences in permeance between the membranes and the substrate alone.Synthesis of organozeolites composed of metals and a phosphonate with a bulky group was investigated. Although it was not possible to obtain a nanoporous compound that can adsorb nitrogen, several compounds prepared had long-range order deilved from t-butylphosphonate. Especially, a Zn/t-butylphosphonate/methylphosphonate system gave a product with an XRD reflection at d=25Å, in which both the phosphonates are incorporated in the framework, when trioxane was added. Also organozeolites composed of nitrilotrisphosphonate and alumimum were attempted to prepare. The product obtained when trioxane was added seemed to possess a three-dimensional framework though there is no nanopore that can adsorb nitrogen.
尝试采用水热法和蒸汽辅助转化法在多孔氧化铝基底上合成甲基膦酸铝膜。当拟薄水铝石、甲基膦酸、水和叔丁醇混合时,将部分混合溶液吸入基质中,将基质浸入溶液中,然后在160℃的高压釜中进行水热处理,AlMepO-β结晶,在基质上形成膜状聚集体,这可能是基质内部复合形成的结果。当将相同的混合溶液吸入基材中,干燥基材,随后在高压釜中蒸煮时,获得40μm厚的AlMepO-α膜,其中微晶生长为紧密接触基材的表面和内部。然而,氧气、空气和氢气的单一气体渗透实验表明,膜和基材之间的渗透性差异可以忽略不计。研究了由金属和具有大基团的膦酸酯组成的有机沸石的合成。尽管不可能获得可以吸附氮的纳米多孔化合物,但制备的几种化合物具有由膦酸叔丁酯衍生的长程有序。特别是,当添加三恶烷时,Zn/叔丁基膦酸酯/甲基膦酸酯体系产生了在d=25埃处具有XRD反射的产物,其中两种膦酸酯都结合在骨架中。还尝试制备由次氮基三膦酸盐和铝组成的有机沸石。添加三恶烷时获得的产物似乎具有三维骨架,尽管没有可以吸附氮的纳米孔。
