1. a kind of method for producing sec-butylbenzene, this method is included the charging comprising benzene and carbon tetraalkyl agent in reaction temperatureFor 110~200 DEG C, reaction pressure is 1~5MPa, and the molar ratio of benzene and carbon tetraalkyl agent is 2~10, based on carbon tetra-alkylationWhen the charging weight (hourly) space velocity (WHSV) of agent is 0.1~50 small-1Liquid phase alkylating conditions under contacted with catalyst;

  • Wherein, the catalystInclude following component by weight percentage:

    A) 20~85% silica alumina ratios are 20~100 zeolite;

    The zeolite is handled through organic acid contact, the organic acid choosingFrom oxalic acid;

    B) 15~80% binding agent.
