Versuchsvorschrift

138.18 g of 5-norbornene-2,2-dimethanol (commercially available from Tokyo Kasei Industry Co., Ltd.) was dissolved in 481.63 g of ethanol, and 6.92 g of 5% Pd—C was added, then a hydrogen balloon was attached and the mixture was stirred for 6 hours. The Pd—C was filtered off, then the reaction solution was concentrated and dried to thereby obtain 129.83 g of 2,2-norbornanedimethanol (purity by gas chromatography: 99.1%, yield: 92.9%).
