Production of alicyclic polycarboxylic acid ester mixtures for use as plasticisers involves hydrogenation of the corresponding aromatic ester, e.g. di-isononyl phthalate using a nickel-zinc catalyst

摘要

A catalyst containing nickel and zinc is used in a method for the production of alicyclic polycarboxylic acid ester mixtures (I) by catalytic hydrogenation of the corresponding aromatic esters. An Independent claim is also included for mixtures of plastics and (I).
