ABSTRACT:
The invention relates to a method for making a catalyst which contains palladium and/or its compounds and, if desired, additionally gold and/or gold compounds and which contains as activators alkali metal compounds and, if desired, additionally cadmium compounds on a support which is composed of SiO.sub.2 or an SiO.sub.2 -Al.sub.2 O.sub.3 mixture having a surface area of 50-250 m.sup.2 /g and a pore volume of 0.4-1.2 ml/g and whose particles have a particle size of 4 to 9 mm, 5 to 20% of the pore volume of the support being formed of pores having radii of 200 to 3000 .ANG. and 50 to 90% of the pore volume being formed of pores having radii of 70 to 100 .ANG.. The support particles are compressed with the aid of an Li, Mg, Al, Zn or Mn salt of a C.sub.2 -C.sub.20 carboxylic acid or a mixture of such salts as binder.
