(57) [Summary] (Modified) [Purpose] Low cost and high yield of alicyclic diketone compound, A method for producing with high purity is provided. [Structure] The alicyclic diol compound of the general formula 1 is dehydrogenated in a liquid phase in the presence of one or more kinds of catalysts selected from the group consisting of copper-based catalysts and Raney-based catalysts to give the general formula 2 To produce the alicyclic diketone compound. [X is a single bond, -CH 2 -, - C ( CH 3) 2 -, - O - or -SO 2 - represents a. R 1 and R 2 are the same or different and each represent hydrogen or a C1-6 alkyl group. m and n are the same or different and each represents an integer of 0 to 2. ] [X, R 1 , R 2 , m and n have the same meanings as in General Formula 1. ] |
