Abstract
The present invention relates to a mixture of diisononyl esters of 1,2-cyclohexanedicarboxylic acid, wherein the isononyl radicals of the diisononyl esters present in the mixture have a degree of branching of from 1.2 to 2.0, to a process for its preparation and to the use of such mixtures.
Claims24
A mixture of diisononyl esters of 1,2-cyclohexanedicarboxylic acid,
- wherein
- the isononyl radicals of the diisononyl esters present in the mixture have a degree of branching of from 1.2 to 2.0.
A process for preparing mixtures of diisononyl esters of 1,2-cyclohexanedicarboxylic acid from
- a mixture of isomeric nonanols which has a degree of branching of from 1.2 to 2.0 in the preparation of the diisononyl esters comprising reacting the mixture of isomeric nonanols with phthalic acid or phthalic anhydride in an esterification step to give diisononyl phthalates and subsequently ring-hydrogenating said diisononyl phthalates.
