Abstract: In a halogenated aromatic isomerization method using a zeolite-containing catalyst composition, dissolved oxygen is decreased so that the halogenated aromatic material contains 15 wt ppm or less of dissolved oxygen. As a result, the life or regeneration period of the catalyst can be prolonged. In particular, the method may employ a zeolite catalyst composition in which the maximum diameter of secondary particles of the zeolite in the catalyst composition is 5 microns or less.

Abstract: A catalyst composition for transalkylation of alkylaromatic hydrocarbons which exhibits a percentage conversion of ethyltoluene higher than 50 wt%, is composed of mordenite (100 pbw), inorganic oxide and/or clay (25-150 pbw), and at least one metal component selected from rhenium, platinum and nickel, and contains mordenite such that the maximum diameter of secondary particles of mordenite is preferably smaller than 10 mu m. In a process for producing xylene from alkylaromatic hydrocarbon feedstock containing C9 alkylaromatic hydrocarbons containing more than 5 wt% ethyltoluene and less than 0.5 wt% naphthalene, the feedstock is brought into contact with the catalyst in the presence of hydrogen.

Abstract: In a process of halogenation of benzene or benzene derivatives, di-substituted halobenzene derivatives having para-aromatic compounds or tri-substituted halobenzene derivatives having 1,2,4-substituted aromatic compounds are selectively produced. In halogenation of benzene or benzene derivatives, a fluorine-containing zeolite catalyst such as L-type zeolite, or a zeolite catalyst having the crystal size of at most 100 nm is used. The reaction is preferably effected in the presence of a solvent, and the solvent is preferably a halogenated compound.
