Versuchsvorschrift

The following run was carried out with another hydrogenation catalyst. A 100-ml three-necked flask equipped with a stirrer and a hydrogen gas inlet connected to a hydrogen gas reservoir equipped with a buret was charged with 20 ml (17.3 g) of the above distillate containing 7-octen-1-al, 20 ml of n-hexane and 0.5 g of a Raney nickel catalyst "NDT-65" (nickel content 45%; Kawaken Fine Chemicals), and the reaction was effected by stirring at room temperature and atmospheric pressure. With the progress of the reaction, hydrogen absorption began, and 3.85 liters of hydrogen was absorbed in 3.5 hours, when the reaction was stopped. The liquid reaction mixture was analyzed by gas chromatography. The n-octanal/n-octanol mole ratio was 69/31. No peaks for other products were detected.
