摘要
采用气相色谱-脉冲火焰光度检测器(GC-PFPD)与气相色谱-质谱(GC-MS)联用技术,分析研究炼油厂精制丙烯原料中的微量硫化物.通过对原料丙烯中的微量硫化物进行富集,采用GC-MS技术与标准品定性,首次从丙烯中检测到异丙基二硫醚和异丙基三硫醚.
A trace sulphide in refined propylene feedstock of refinery were analyzed and investigated by using a combined technology of gas chromatography-pulsed flame photometic detector（GC-PFPD） and gas chromatography-mass spectroscopy（GC-MS）.By means of enrichment of the trace sulphide,the isopropyl disulphide ether and isopropyl trisulphide ether in the propylene were first detected by using GC-MS and standard substance.
