ABSTRACT:
In a method for the production of .alpha.-tetralone wherein tetralin is oxidized in the absence of a catalyst at a temperature of from 50.degree. to 100.degree. C. to an extent that the conversion of tetralin into tetralin hydroperoxide is 25 to 35 percent by weight, thereby producing a solution of tetralin hydroperoxide in tetralin, and wherein an inorganic metal salt is added to said solution to decompose the tetralin hydroperoxide to .alpha.-tetralone, the improvement comprising adding to said solution, as said inorganic metal salt, a mixture of at least one water-soluble inorganic iron salt and at least one water-soluble inorganic copper salt at a temperature of from 0.degree. to 90.degree. C.
