Page/Page column 19, (2008/06/13)
A method of efficiently extracting a high-purity stereoisomer from a mixture comprising the endo isomer and the exo isomer of a dicarboxylic acid having a norbomene or norbomane structure, or a derivative thereof. The present invention relates to a method of separating the endo isomer and the exo isomer of a dicarboxylic acid represented by a general formula (1) or (2) or a derivative thereof, and includes the step of stirring and mixing a mixture comprising mainly the endo isomer of the dicarboxylic acid represented by the general formula (1) or (2) or a derivative thereof, and the exo isomer of the dicarboxylic acid represented by the general formula (1) or (2) or a derivative thereof, with a basic compound and a solvent. (wherein, R1 to R8 represent a hydrogen atom, methyl group, ethyl group, or butyl group), (wherein, R'1 to R'10 represent a hydrogen atom, methyl group, ethyl group, or butyl group)
