摘要
利用高温气相色谱法对柴油中正构烷烃的碳数分布及含量进行了分析。同时根据所得数据计算出正构烷烃的平均相对分子质量及平均碳原子数。试验表明，气相色谱的最佳测定条件为：柱初温60℃，柱终温330℃，升温速率6℃／min，汽化室温度350℃。分析出吐哈两种柴油中C11～C19的正构烷烃均占分析总量的75％以上，吐哈0^#与-10^#柴油正构烷烃的平均相对分子质量、平均碳原子数分别为214．57、15．18和203．34、14．38。所得数据为设计研究针对吐哈原油有效降凝剂提供了参考数据。
The contents of n-paraffin and carbon number distribution in n-paraffin wax of diesel oil of Tuba in Xinjiang were determined by high temperature gas chromatography with capillary column （30 m × 0.25 mm） and FID. The optimal chromatographic conditions were as follows： FID temperature 350 ℃, column temperature beginning at 60 ℃, ending at 330 ℃, the increasing rate of temperature 6 ℃/min. Diesel oil 0^# and diesel oil - 10^# were analyzed under above conditions. Results showed that n-paraffin was separated successfully from each other. The results would be regarded as an important reference for future research of pour point depressant of diesel oil.
