Abstract
This invention relates to a method of efficiently producing a high-purity para-substituted aromatic hydrocarbon while suppressing caulking without requiring isomerization-adsorption separation steps, and more particularly to a method of producing a para-substituted aromatic hydrocarbon, characterized in that a methylating agent and an aromatic hydrocarbon are reacted in the presence of a catalyst formed by coating MFI type zeolite having a particle size of not more than 100 μm with a crystalline silicate.
