摘要
提出了一种分析丙烯腈中微量杂质的大孔径OV-101和OV-17SCOT串联柱及毛细管进样系统。结果表明串联柱具有寿命长和分离效率高的特点,定量分析误差小于4%。
A megabore SCOT series column of silicone OV 101 and OV 17 for the analysis of micro amount of impurities in acrylonitrile is presented. By using the columns of 50m×0 53mm i. d. OV 101 and 25m×0 53mm i. d. OV 17,with column temperature of 75℃ and N 2 as carrier gas, u =8cm/s, the main impurities, such as acrolein, acetone and acetonitrile may be well separated from acrylonitrile in 26 min. The results indicate that the series column possesses of high separation efficiency and long column life. The error in quantitative analysis was less than 4%.
