| Abstract: | The analysis of reaction system,in which 1,2,3,5-tetramethylbenzene was catalytically converted to 1,2,4,5-tetramethylbenzene, was investigated on the glass capillary column covered with polyethylene glycol 20M by gas chromatography.Quantitative determinatlon was carried out by using the corrected area normalization,The variation coefficience of relative correction factors were less than 2 %. The relative errors of the component were less than 3%. |
