Summary: | The present invention relates to the preparation of alicyclic polycarboxylic esters by ring-hydrogenation of the corresponding aromatic polycarboxylic esters on a catalyst which comprises at least one metal from the triad iron, cobalt, nickel, and at least one metal of the IInd, IIIrd, IVth, Vth, and/or VIth transition group of the Periodic Table. An alicyclic carboxylic ester mixture with a proportion above 10 mol % of the trans isomers. The use of the alicyclic polycarboxylic ester mixtures. Mixtures made from plastics and from alicyclic polycarboxylic ester mixtures. |
