Abstract:
    A process for dicarboxylic acid production which comprises oxidatively cleaving a cycloalkane with oxygen in a liquid phase with a continuous reactor in the presence of a catalyst to produce the corresponding dicarboxylic acid, characterized in that the residence time tau (hr) is regulated so as to be in the following range: 0.1
Time: 10
