Abstract: The invention relates to the use of a cyclohexane polycarboxylic acid or of one of its derivatives, or of a mixture of one or more of said acids as plasticizers in the production of plastics which are rated toxicologically favourable. In animal experiments, using rodents, to which a daily oral dose of 1000 mg/kg body weight of the corresponding cyclohexane polycarboxylic acid, or a derivative thereof, or a mixture of two or more of said acids is administered by oesophageal tube over a period of at least 14 days, said dose, in comparison to untreated control animals, leads neither to a significant increase in the weight of the liver after treatment, nor to a doubling of the specific cyanide-insensitive palmitoyl-CoA oxidase activity, measured in the liver homogenisate.

Abstract: Cyclohexane-polycarboxylic acids or their derivatives which do not cause a significant increase in liver weight or a doubling of specific enzyme activity in liver homogenates when tested in rodents at oral dosage levels of 1000 mg/kg per day for at least 14 days, are used as plasticizers for toxicologically acceptable plastics. Cyclohexane-polycarboxylic acids or their derivatives (or mixtures of these) which do not cause a significant increase in liver weight or a doubling of the specific activity of cyanide-insensitive palmitoyl-CoA oxidase in liver homogenates after administration to rodents by stomach tube at a daily dosage of 1000 mg/kg body weight for at least 14 days are used as plasticizers for the production of toxicologically acceptable plastics.

Abstract: 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.

Abstract: The hydrogenation of esters of benzene-dicarboxylic acids is carried out on supported catalysts containing a Sub-Group VIIII metal on a macroporous support. A process for the hydrogenation of benzene-dicarboxylic acid ester(s) with hydrogen in presence of a supported catalyst containing Sub-Group VIII metal(s) on a macroporous support. If the ester is dimethyl terephthalate, this excludes hydrogenation on a catalyst containing ruthenium, with or without Sub-Group I, VII or VIII metal(s), on a support with an average pore diameter (APD) of at least 50 nm and a BET surface of not more than 30 m /g, with an active metal content of 0.01-30 wt.% and a ratio of (active metal surface):(support surface) of less than 0.05, and/or on a catalyst containing 0.01-30 wt.% active metal(s) as above on a support in which 10-50 vol.% of the pores consist of macropores with a diameter of 50-10,000 nm and 50-90 vol.% consist of mesopores with a diameter of 2-50 nm.
