Product Applications

It is mainly used to produce phthalic anhydride; It is used as chromatographic standard substance and solvent; O-Xylene is the raw material of bactericide rust-killing Amine, tetrachlorobenzene peptide and herbicide bensulfuron methyl, which is used to manufacture O-methyl benzoic acid as intermediate.; Mainly used as chemical raw materials and solvents. Can be used to produce phthalic anhydride and dye..

Production method

Industrial use of super distillation method to separate O-xylene from mixed xylenes. The boiling point difference between O-xylene and other components in mixed xylene is more than 5℃. During distillation, the number of tower plate is about 150, and the reflux ratio is 5-8, which requires more energy consumption.
