The mixture described is a mixture of isomeric nonanol diesters of a dicarboxylic acid, selected from the class consisting of a mixture of diesters of adipic acid in the 1H NMR spectrum of which, observed in CDCl3, the ratio of the area under the resonance signals at chemical shifts in the range from 1.0 to 2.0 ppm with respect to TMS to the area under the resonance signals at chemical shifts in the range from 0.5 to 1.0 ppm with respect to TMS is from 1.20 to 5.00 and a mixture of diesters of phthalic acid, in the 1H NMR spectrum of which, observed in CDCl3, the ratio of the area under the resonance signals at chemical shifts in the range from 1.1 to 3.0 ppm with respect to TMS to the area under the resonance signals at chemical shifts in the range from 0.5 to 1.1 ppm with respect to TMS is from 1.00 to 4.00. The diesters of adipic and phthalic acid are suitable as plasticizers for PVC-based molding compositions and have high compatibility, a low cold crack temperature, low torsional rigidity and/or high thermal stability.
A mixture of isomeric nonanol diesters of adipic acid in the 1H NMR spectrum of which, observed in CDCl3, the ratio of the area under the resonance signals at chemical shifts in the range from 1.0 to 2.0 ppm with respect to TMS to the area under the resonance signals and chemical shifts in the range from 0.5 to 1.0 ppm with respect to TMS is from 1.20 to 5.00.
A mixture of isomeric nonanols which
A mixture of isomeric nonanols, obtained by hydroformylating an isomeric octenes mixture in the presence of a cobalt catalyst and hydrogenating the hydroformylation product, where the isomeric octenes mixture is obtained by bringing a butene-containing hydrocarbon mixture which comprises 5% by weight or less of isobutene, based on the total butene content, into contact with a heterogeneous catalyst comprises, as significant active constituents, from 10 70% by weight of nickel oxide, from 5 to 30% by weight of titanium dioxide and/or zirconium dioxide and from 0 to 20% by weight of aluminum oxide, and the remainder is silicon dioxide.
A mixture of isomeric nonanol diesters of phthalic acid, in the 1H NMR spectrum of which, observed in CDCl3, the ratio of the area under the resonance signals at chemical shifts in the range from 1.1 to 3.0 ppm with respect to TMS to the area under the resonance signals at chemical shifts in the range from 0.5 to 1.1 ppm with respect to TMS is from 1.00 to 4.00.
