Abstract: PURPOSE: To inactivate a cobalt catalyst, whose catalytically active material is specified, to a base so that its long use in the basic medium is sufficiently guaranteed by calcining the catalyst material at one specified final temperature in a first step and at another specified final temperature in a second step. CONSTITUTION: The catalytically active material of the cobalt catalyst comprises 55-98 wt.% cobalt, 0.2-15 wt.% phosphorus, 0.2-15 wt.% manganese and 0.2-15 wt.% alkali metal, calculated as oxides and is calcined at 550 deg.C-750 deg.C and 800 deg.C-1000 deg.C final temperatures in the first and second steps, respectively to obtain the objective cobalt catalyst having 1.5-500 m /g, preferably 5-300 m /g, more preferably 10-250 m /g surface area.
