Abstract: Fe₂(SO₄)₃/bentonite solid acid catalyst was prepared, which the bentonite was disposed using H₂SO₄ and the catalyst carriers dipped with Fe₂(SO₄)₃ solution. The influence of H₂SO₄ mass fraction, Fe₂(SO₄)₃ concentration and activation temperature on the Fe-B/SO₄^2- catalytic performances through isopropylation reaction of naphthalene was investigated. The suitable preparing technology conditions were obtained as follows: H₂SO₄  mass fraction is 10%, Fe₂(SO₄)₃ concentration is 0.08 mol/L and activation temperature is 200 ℃. Meanwhile, the Fe₂(SO₄)₃/bentonite catalyst was characterized by XRD, BET, TG and SEM methods, respectively.
