Versuchsvorschrift
The procedure of Example 5 was repeated with 5 g of Raney Ni/Mo being installed. 100 g/h of butynediol solution were hydrogenated at a reactor temperature of about 122° C., 20 bar and 300 l/h of hydrogen. At a space velocity of liquid of 225 m3/m2·h and a kLa of 0.3 s−1 and complete butynediol conversion, n-butanol contents in the product of 2.2-2.7% by weight were obtained, with the 1,4-butanediol content being 77% by weight and the remainder being intermediates. After increasing the space velocity of liquid to 263 m3/m2h, corresponding to a kLa of 0.4 s−1, the n-butanol content fell to 1.3% by weight, the butanediol content rose to 88% by weight.
