| Gas chromatographic external standard method was used to analyze the dimethylnaphthalene extracted from wash oil. External standard analysis method was set up and standard curves were obtained. The accuracy of the standard curves were proved through testing. Thus a rapid and precise analysis for small amounts of impurities contained in 1,4-dimethylnaphthalene was realized. |
