Procedure

Before the reaction, the reaction system was charged in a similar way to Example 1 with 20 g of Raney Ni/Mo in 300 ml of water. At 30 bar and a reactor temperature of from 145 to 151° C., the product was obtained in an amount of 213 g/h and comprised 93.3% by weight of butanediol, 0.3% by weight of 2-methylbutanediol, 1.5% by weight of n-butanol, 4.2% by weight of n-propanol and a few further products in amounts of less than 0.08% by weight. The STY was about 0.25 kg of butanediol/l·h.
