Determination Of 1, 2, 4-trimethyl Benzene And Its Impurity Hydro Carbons

There are not industry standard and national standard on the determination of 1,2,4-trimethyl benzene and hydro carbons, using gas chromatography. In view of existing situation, it is necessary to set up a method to determine 1,2,4-trimethyl benzene and its purity hydro carbons. With domestic market rapid development, enterprises of producing and using 1,2,4-trimethyl benzene are more and more. But, there is different to trade fairly and undebatably with respective methods of manufactures and users.It was studying on chromatographic column, typical operating conditions, accuracy and precision of the method set up in the thesis. 5% benzene silicon and 95% polyethylene glycol glass capillary columns, FID detector and the programmed column temperature in gas chromatography were sued。The method could be applied to determine not only 1,2,4-trimethyl benzene and hydro carbons, but others trimethyl-benzene isomers and C10 nonbenzenoid aromatic hydrocarbon.Key words:1,2,4-trimethyl benzene hydro carbons gas chromatographyType of article:applied research...
