补充资料：4A沸石
分子式：
CAS号：
性质：又称Na12[(A1O2)12、(SiO2)12]27H2O 又称4A分子筛。白色固体颗粒。呈网络状结构，内含均匀小孔，孔径0.42nm，比表面积约为600m2/R，不溶于水和有机溶剂，能溶解于强碱和强酸。加热超过800℃时，重新结晶形成白硅石状的结构。有吸附水分，液体、气体及不饱和的有机物质。对钙离子有交换能力，理论交换能力为352CaCO3mg/g，一般为290～320mgCaCO3/g，白度≥95%，pH值10～11.5，表观密度0.3～0.5g/cm3，平均粒径为2μm，粒度分布≤4μm占85%以上。用作无磷洗涤剂的助剂，代替三聚磷酸钠；在石油和其他工业用作气体和液体的干燥、脱水净化等，也用作催化剂和软水剂。
