Summary:PROBLEM TO BE SOLVED: To provide a xylene production method which is based on subjecting a raw oil consisting of a petroleum distillate to a disproportionation reaction or a transalkylation reaction and produces xylene in a high yield while selecting an appropriate raw oil.SOLUTION: A method of producing xylene comprises subjecting a raw oil containing a petroleum distillate as a base material to a transalkylation reaction or a disproportionation reaction and uses a raw oil containing 7-10C alkylbenzenes with an average value of numbers of methyl groups bonded directly to the individual benzene rings of the alkylbenzenes of 1.2-2.8. 【課題】石油留分からなる原料油に不均化反応またはトランスアルキル化反応を施してキシレンを製造する場合において、適切な原料油を選択しつつ高い収率でキシレンを製造する方法を提供する。【解決手段】石油留分を基材とする原料油にトランスアルキル化反応または不均化反応を施してキシレンを製造する方法であって、前記原料油として、炭素数７〜１０のアルキルベンゼン類を含み、当該アルキルベンゼン類の各ベンゼン環に直接結合するメチル基数の平均値が１．２〜２．８であるものを使用することを特徴とするキシレンの製造方法である。【選択図】なし
