摘要:
The invention relates to a manganese dioxide catalyst which contains at least one lanthanide compound which is used for the hydrolysis of organic nitriles, which supports easily oxidisable groups such as thiol or thioether groups, to produce the corresponding carboxylic acid nitriles. The invention also relates to a method for producing said catalyst and to the use thereof for the hydrolysis of organic nitriles.
