Versuchsvorschrift

150 g (499 mmol) of dimethyl 1,15-pentadecandioate and 750 mg (0.5% by weight per the diester) of a commercial copper-chromium catalyst (content of copper as copper oxides: 42% by weight) were added to an autoclave and subjected to hydrogenation reaction at the hydrogen pressure of 20.0 Mpa at 280° C. After 2 hours, methyl 15-hydroxypentadecanoate was obtained in 35% yield. The degree of the conversion was 67% the selectivity was 53%, and the yield was 35%.
