裂解汽油中CS_2及低碳硫醇的气相色谱测定法

Determination of CS_2 and low carbon levels mercaptan of pyrolysis gasoline by gas chromatography

提出采用Agilent PONA毛细管色谱柱测定裂解汽油中CS2及低碳硫醇组分的气相色谱方法。在本文提出的条件下,CS2及低碳硫醇各组分分离良好,检出限低于0.5mgS.L-1,结果准确可靠,方法满足控制分析的要求。

The method of a Agilent PONA capillary gas chromatography is presented to determine CS2 and low carbon levels mercaptan in pyrolysis gasoline. Under the selected conditions, CS2 and low carbon levels mercaptan is separated with good resolutions. The detection limit is below 0.5mgS· L^-1. The method can be applied satisfactori-ly to the process analysis.
