In a high concentration of chain transfer agent ethanethiol, the GC-MS analysis of oligomers obtained by the plasma initiated polymerization of liquid monomers permits identifying and determining all compounds formed in the early propagation steps. From its analytical data the exactstructure of the starting chain end could be obtained, and allowed a more detailed description of theinitiating active species which is the ester group being produced by the monomer split-ted in plasma zone.

GC-PFPD was used to analyze the composition and identification of sulfides in liquid propylene.The method was applied to evaluate the effectiveness of individual desulfurization facilities in Jinan Petrochemical Branch Company, SINOPEC. The analysis results indicated that hydration reactor T702CD could completely convert COS in liquid propylene into H2S and other sulfides, and desulfurization column T702AB could completely remove H2S from liquid propylene. But these columns basically could not remove dimethyl sulfides. The identified propyl mercaptan and dimethyl sulfide might be produced by side reactions during COS hydration. Possible side reactions and mechanisms of their formation were proposed. The estimated results coincide well with the analytical data.

利用自行建立的液态丙烯中硫化物形态鉴定及含量分析方法,对中国石油化工股份有限公司济南分公司的丙烯精制装置进行了脱硫效能评价。结果表明,脱硫塔能有效脱除液态丙烯中的COS和H2S,但对丙烯中的硫醚基本没有转化脱除能力。通过对装置标定数据的分析,发现丙烯聚合装置进料中所含的微量硫醚源于COS水解过程发生的副反应,并对此副反应的反应方程式及其机理进行了推测,结果与测定结果相吻合。
