Abstract (en)

[origin: WO2004113261A1] The invention relates to a distillation method for isolating a compound comprising at least two functional groups, selected independently of one another from a group consisting of a nitrile group, carboxylic acid group, carboxylic acid ester group and a carboxamide group from a mixture containing a compound comprising at least two functional groups, selected independently of one another from a group consisting of a nitrile group, carboxylic acid group, carboxylic acid ester group and a carboxamide group and a rhodium containing compound that is homogeneous in the mixture.
