  • Patent number: 10364206
    Abstract: The purpose of the present invention is to provide a method for producing 2-halogenated benzoic acids, the method imparting high regioselectivity (high selectivity) and having a shorter reaction time than does the conventional reaction. This method for producing 2-halogenated benzoic acids, in order to achieve the above purpose, is characterized in that benzoic acids and a halogenating agent are reacted in the presence of an alkaline compound, making it possible to highly selectively obtain 2-halogenated benzoic acids.

  • Patent number: 8988743
    Abstract: According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The light-emitting element is not used for reading an image of the document. The photoelectric conversion element converts light projected onto the detection position into an electric signal and outputs the electric signal. The light-emission controller changes the light quantity of the light emitted by the light-emitting element during a predetermined interval. The detection processor detects the presence or absence of the document at the detection position of the document based on whether a value of the output electric signal during the predetermined interval changes in correspondence to the change of the light quantity caused by the light-emission controller.
