| 摘 要： | 采用分子筛４次吸附的方法测定微晶蜡的正、异构烷烃含量，并与气相色谱法的结果对比，其一致性较好。本方法所用仪器简单，操作简便，数据重复性较好，相对标准偏差在±５．９％以内，实用性较强，具有推广价值。结合前文所建立的分子筛吸附测定石蜡中正、异构烷烃含量的方法，可实现石蜡、混晶蜡和微晶蜡中正、异构烷烃含量的测定。

| Abstract: | A method for the determination of the amounts of n and i paraffines in microcrystal wax, using 5A molecular sieve as adsorbent and isooctane as solvent, and under the conditions of reflux, was discussed, The results were compared with that of GC The method is simple to operate and gives an accurate and pricise result with the RSD less than ±5 9% |
