摘要
采用气相色谱-质谱联机分析,确定了回收溶剂中影响异戊二烯聚合的主要杂质为防老剂A和2-甲基呋喃,并通过聚合评价试验研究了这些杂质对异戊二烯聚合转化率影响的基本规律,确定了回收溶剂中这些杂质含量指标,该研究能为精馏回收溶剂提供有效的技术指导。
The major impurities antioxidant A and 2-methyl-furan,which impacted the polymerization of isoprene in recovery solvent,were determined by gas chromatography-mass spectrometry analysis.The influence of concentration cf antioxidant A and 2-methyl-furan on the conversion of isoprene polymerization was investigated,determining the indicators of these impurities in recovery solvent.The study can provide effective technical guidance to recovery solvent by distillation.
