摘要：
The present invention relates to processes for preparing carboxylic acid derivatives, comprising the reaction of at least one carboxylic acid and/or of a carboxylic acid derivative with at least one alcohol and/or an amine in the presence of a metal-containing catalyst, wherein, after the reaction has ended, the metal-containing catalyst is contacted with water and a superabsorbent, the contacting of the catalyst with the water leading to hydrolysis of the catalyst. The present invention further relates to the use of superabsorbents for removing a metal-containing catalyst from a mixture after hydrolysis of the catalyst.
