摘要: There is provided a method and an apparatus for producing an oxidized compound, which includes measuring an electric potential of an oxidation reaction solution for producing an oxidized compound by an oxidation reaction, and determining an end point of the oxidation reaction on the basis of a predefined decrease of the electric potential, thereby simply determining the end point of the oxidation reaction to swiftly move on to the next step. For example, the apparatus for producing an oxidized compound has a reactor (1) for carrying out an oxidation reaction; an oxidation reduction potential detection means (5) for detecting the value of an oxidation reduction potential of an oxidation reaction solution in the reactor; and a determination means (6) for monitoring at all time the detected values of the oxidation reduction potential detected by the oxidation reduction potential detection means and determining a point where the amount of an electric potential dropped from a highest electric potential of the oxidation reduction potential reaches the predefined amount of an electric potential, as an endpoint of the oxidation reaction, in which the apparatus allows to carry out the method of the invention at an industrial production level.
