| Abstract: | The contents of hydrocarbon in extraction solvent sulfolane for the extraction of aromatic hydrocarbon are determined by gas chromatography.The recovery range of the add known components is between 93% to 107%.The RSD in poor- and rich-solvent are 0 02% and 0 01% respectively.GC method is proved to be simple and efficient,and has the advantage of being able to determine the contents of heavy aromatic and heat carrier in the extraction solvent which are not detectable with distillation method. |
