Determination of Trace Acetonitrile in the Acetonitrile Extracted Butadiene |
| |
| Abstract: | The method of determination of trace acetonitrile in the extract of butadiene is introduced. The method applies capillary column with large inside diameter and a thermionic specific detector. The detection limit reaches 0.1 mg/kg, and the test time is only 3 min. Compared with the national standard GB6015 85, the method has the advantage of higher sensitivity and shorter test time. |
