1 INTRODUCTION Numerous recent reports have been focused on the construction of supramolecular architectures by using some special tripodal ligands with aromatic ring platforms[1~5]. Mixing this kind of ligands with metal ions in a suitable solution generally yields typical 1D, 2D and 3D coordination polymers or large nanometer-sized cavities supposed to be use- ful for catalysis, molecular selection, ion exchange, specific chemical transformations et al.[6~11]. Now our group is inte… 相似文献

2MgO·2B_2O_3·MgCl_2·14H_2O-H_3BO_3-H_2O体系30℃相平衡 总被引:5,自引:0,他引:5
用相平衡方法研究了2MgO·2B_2O_3·MgCl_2·14H_2O-H_3BO_3-H_2O在30 ℃ 不同浓度H_3BO_3水溶液中的溶解转化产物及其溶解度。结果表明,氯柱硼镁石的 溶解转化产物,在H_3BO_3质量分数≤2.50%时为多水硼镁石;在2.50% ~ 5. 00%H_3BO_3范围时为库水硼镁石;当H_3BO_3量在5.00% ~ 5.60%之间时为章氏硼 镁石;而当H_3BO_3量≥5.60%时为三方硼镁石。提出了溶解相转化机理。 相似文献
