In the reaction of mesitylene gas-liquid catalytic air oxidation to trimellitic acid and related processes, in order to better control the product quality and improve the reaction yield, it is necessary to establish a set of reliable and complete analytical methods. . In this experiment, try to analyze the reaction components with chromatography, mass spectrometry, infrared spectroscopy, atomic absorption spectroscopy and chemical titration as the main analysis methods. This article focuses on the research and establishes related analysis methods. For gas analysis, O_2, N_2, CO_2 were separated using double columns in parallel at room temperature, and gas chromatography TCD was used for quantitative analysis. For the liquid, a 15-meter capillary column with DMF as the internal standard and OV-101 as the stationary phase was used to successfully carry out the quantitative analysis of mesitylene and acetic acid using gas chromatography FID. For the high-polarity, high-boiling point solid product of trimellitic acid, it was characterized by infrared spectroscopy, GC-MS, gas chromatography, acid value titration and other analytical methods: infrared spectroscopy and GC-MS were used for product qualitative analysis. Analysis and comparison with standard spectra made under the same instrument and under the same conditions; Trimethyl trimellitate was prepared by sulfuric acid-methanol esterification method and fast esterification method, and it was quantified by gas chromatography FID Analysis to determine the purity of trimellitic acid in the solid product; acid-base titration was used to determine the acid value of the solid product to verify the purity of trimellitic acid in the solid product. The above analysis method is simple to operate and convenient to apply. It provides a lot of data for process control and optimization. It has been successfully applied to the reaction of mesitylene gas-liquid catalytic air oxidation to trimellitic acid and related processes.
