| 摘 要： | 用原位合成方法成功地制备了一类新型NaA分子筛毛细管柱 ,与传统柱型相比 ,原位合成柱的分子筛层更加均匀与致密、分离效果更佳。在此柱上涂敷不同极性的固定液制备了一类新型气 液分子筛改性SCOT柱 ,测试表明该柱型分离效果较佳、热稳定性好 ,其中超短柱及大口径柱的成功应用更显示该柱型具有很高的实际应用价值 ,值得推广。

| Abstract: | A new kind of NaA zeolite column has been prepared by in situ synthesis technique In comparing with traditional coating method, the in situ NaA zeolite carrier is much more uniform and rigid Several kinds of zeolite gas liquid modified columns have been prepared with this in situ technology, which showed satisfactory features in separation property and thermal stability The successful utilization of mini length and wide bore columns showed good practical prospect of this new kind of zeolite column |
