化學沉澱法制備超細二鹽基亞磷酸鉛粉體In this paper we studied the intercalation behavior of a new host matrix of x = l of zirconium proline - n - mtthyl phosphonate - phosphate ( a - zpmpp ), we successfully introduced butylamine heptylamine decanylamine ethanolamine diethylenetriamine ( 2e3a ) triethyleneteriamine ( 3e4a ) and tetrathyleneoctamine ( 4e5a ) guest molecules into a - zpmpp interlayer space. the intercalation complex were characterized by ir spectrum x - ray diffraction and tg - dsc thermal analysis, it has been found that a - zpmpp possess different intercalation behavior from a - zrp. because of the bulk of proline group, it affected the amount of guest molecule, mono - alkylamine form mono - molecule layer in the interlayer space, butylamine, decanylamine and ethanolamine form mono - layer and the carbon chain form 90 degree ordered assembly with the zirconium floor of a - zpmpp, every host molecule absorbed 0. 5 guest molecule
本文報道首次以x ? l的層狀（脯氨酸十一甲基磷酸一磷酸氫）鉛（ a zpmpp ）為主體底物，成功地將客體分子：正丁胺、正慶胺、正癸胺、乙醇胺、二乙烯三股、三乙烯四胺、四乙烯五股插入層狀化合物a zpmpp的層間，通過紅外光譜（ ir ） 、 x射線衍射（ xrd ） 、熱重分析（ tg dsc ）等手段對插層復合物進行結構表徵，結果表明： x ? l的層狀（脯氨酸件一甲基磷酸一磷酸氫）鉛具有不同於無機磷酸結的插層性能，由於層間脯氨酸基團的體積較大，影響客體分子進入的數量，胺分子在層板間取單層排列。Methods : refers to gems / food recommends the monitor project, the shaoxing special food yellow wine, the dried vegetables, the preserved beancurd, the fragrant cake, the sauce duck carried on the lead, the arsenic, the cadmium, the organochlorines, the organic phosphorus, the pyrethrum, the synthetic colour, the sorbic acid, the benzoic acid, the nitrite monitor were determined
