CATALYST FOR REACTING CARBOXYLIC ACID NITRILES

摘要

The invention relates to a catalyst for reacting carboxylic acid nitriles with water, the catalyst comprising at least 60% by weight of manganese dioxide having the empirical formula MnOx, wherein x is in the range of 1.7 to 2.0, and at least one plasticizer. The invention further relates to a method for producing the catalysts mentioned above and to a method for producing carboxylic acid amides by reacting carboxylic acid nitriles with water in the presence of the catalyst according to the invention.
