| Abstract: | 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 x 0.53mm i.d. OV-101 and 25m x 0. 53mm i.d. OV-17, with column temperature of 75 degrees C and N2 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%. |
