“…Considerable attention has been given to the manufacture of phenol by the direct oxidation of benzene with air, using a great variety of metallic catalysts ( 31) iodine ( 17), and oxides of nitrogen (5, 6), as well as noncatalytic processes (7, 20, 21). The inclusion of small amounts of organic materials of diverse types has been found to improve the reaction (11,18). However, only three methods have been put into commercial application.…”

“…With the progress of the times, most of the phenol is obtained through a chemical synthesis process. At present, the main methods for producing phenol are isopropyl benzene, toluene oxidation, and benzene direct oxidation [6][7][8][9]. More than 92% of the world's phenols are produced using the cumene process [10].…”

2,4-diphenyl-4-methyl-1-pentene is a main impurity in phenol. In this paper, acidified activated carbon with sulfuric acid were used to remove the impurity from phenol. Combined with solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS), the adsorption capacity and mechanism of acidified activated carbon were analyzed. Unacidified and sulfated activated carbon was characterized by scanning electron microscopy (SEM). The adsorption mechanism of 2,4-diphenyl-4-methyl-1-pentene on sulfuric acid acidified activated carbon was investigated. The acidified activated carbon of sulfuric acid has much better adsorption capacity than the unacidified activated carbon on 2,4-diphenyl-4-methyl-1-pentene. The sulfuric acid acidified activated carbon has no obvious adsorption effectiveness on mesityl oxide and 2-methylbenzofuran. The optimum adsorption time of sulfuric acid acidified activated carbon for 2,4-diphenyl-4-methyl-1-pentene was 1 h, the removal rate was 82%. The Freundlich isothermal adsorption model can describe the adsorption behavior of 2,4-diphenyl-4-methyl-1-pentene on sulfuric acid acidified activated carbon. The adsorption process conforms to the pseudo-second-order kinetics model and is a chemical adsorption. The sulfuric acid acidified activated carbon can remove 2,4-diphenyl-4-methyl-1-pentene form phenol very well, which provide a theoretical basis and technical support for the phenol industry.
