高滴熔点微晶蜡中碳数分布的测定

Determination of Carbon Distribution in Microcrystal Wax

采用冷柱头进样的高温气相色谱技术,建立了测定高滴熔点微晶蜡中正构和非正构烃类含量及碳数分布的方法。对滴熔点在90℃以下的微晶蜡进行测定。实验表明,使用大口径高温毛细管柱可以分析碳数在72以下的微晶蜡。方法快速,准确,实用性强。

A method has been developed to measure the carbon distribution and content of microcrystal wax with high drop melting point. Those wax whose drop melting point are lower than 90 ℃ were measured by on column high temperature chromatography o Experiments show that microcrystal wax with a carbon distribution less than C72 can be analyzed with large diameter quartz capillary column . This method has the advantage of simplicity , convenience , and high accuracy .
