摘要: 生物柴油是石化柴油可靠的替代品,对其进行快速定性定量分析,对生物柴油工业具有重要意义,也是当前分析化学的热点课题。通过对传统的气相色谱分析法进行合理地改进、调整,并与其它各种分析手段联用,可解决研究过程中大部分的分析问题。本文介绍了气相色谱技术在生物柴油分析中的应用现状,重点回顾与讨论了运用气相色谱对烷基酯含量、甘油和甘油酯含量、甲醇含量、类固醇含量的测定、在酯交换反应监控中的应用以及与其它分析技术联用的情况。最后对气相色谱技术在该领域可能的发展趋势作了展望和探讨:将朝着准确度、精度更高,速度更快,分析过程更简便,单次分析的物质种类数目更多的方向快速发展。将气相色谱与其它分析技术联用将会日益普遍。

Abstract: Biodiesel is reliable as an alternative fuel for petroleum diesel. It is crucial and important to analyze biodiesel qualitatively and quantitatively at a high speed,which is a focus issue in the field of analytical chemistry as well. Most analysis of biodiesel can be done through improving and adjusting traditional gas chromatography (GC) method appropriately. The application of GC on biodiesel analysis is introduced. The methods of qualification and quantification of mono-alkyl esters,glycerol and glycerides,methanol,steroids,and the application of GC in transesterafication reaction monitoring,are reviewed and discussed. Also,the prospect of GC development is discussed. It will develop rapidly and become more accurate,more precise,more convenient and faster,the number of material species which can be analyzed at same time will increase as well. Furthermore,it will be increasingly widespread that GC can be used with other technologies together for analysis.
