1-Butanol → 1,4-Butanediol

Participants

Reaction Steps

Using a method similar to Example 1, 170 g/h of butynediol solution were hydrogenated over 10 g of Raney Ni/Mo (2.5% by weight of molybdenum, calculated as Mo). The initial temperature was 150° C. and the reactor temperature rose to 173° C. during the reaction. The product was obtained in an amount of 176 g/h and comprised 92.4% by weight of 1,4-butanediol, 0.4% by weight of 2-methylbutanediol, 2% by weight of n-butanol and 4.7% by weight of n-propanol plus a few further products in amounts of less than 0.08% by weight. The STY was 0.7 kg of butanediol/l·h.
