1949年以来,科学技术上的一项重要成就,是可以用作分子筛吸附剂和催化剂的合成结晶铝硅酸盐沸石的发现和发展。本文报道一种具有异常分子筛性能的新型微孔结晶二氧化硅,即硅沸石的合成、晶体结构和性质。它与亲水的铝硅酸盐沸石不同,是憎水和亲有机物质的,可在水的存在下选择吸附有机分子。 Since 1949, an important scientific and technological achievement has been the discovery and development of synthetic crystalline aluminosilicate zeolites that can be used as molecular sieve adsorbents and catalysts. In this paper, we report the synthesis, crystal structure and properties of a novel microporous crystalline silica with abnormal molecular sieve properties. Unlike hydrophilic aluminosilicate zeolites, which are hydrophobic and organophilic, they selectively adsorb organic molecules in the presence of water.
