    摘要: A method for producing m-hydroxy-acetophenone which comprises allowing m-(2-hydroxy-2-propyl)cumene hydroperoxide to react at 30.degree. to 100.degree. C. in the presence of an aqueous solution containing 0.001 to 1 mole of iron salt per mole of said compound, 0.01 to 4 moles of copper salt per mole of said iron salt, and mineral acid to give m-(2-hydroxy-2-propyl)acetophenone, then allowing the resulting compound to react at 30.degree. to 95.degree. C. in the presence of 1 to 20 moles of 5 to 90% by weight aqueous hydrogen peroxide solution per mole of said compound and acid catalyst to form m-(2-hydroperoxy-2-propyl)acetophenone, and further subjecting the product formed to acid decomposition. m-Hydroxyacetophenone is an important intermediate in the fields of pharmaceuticals, agricultural chemicals, dyestuffs and the like.
