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: The invention relates to selected cyclohexane-1,3- and 1,4-dicarboxylic acid esters, to their use as plasticizers in synthetic materials and to their production. The inventive method of production comprises hydrating the corresponding isophthalic acid and terephthalic acid esters by contacting on e or more of such isophthalic acid or terephthalic acid esters with a hydrogen - containing gas in the presence of a catalyst. Said catalyst contains as the active metal at least one metal of subgroup VIII of the periodic system alon e or together with at least one metal of subgroup I or VII of the periodic system, applied on a substrate. The inventive method is further characterize d in that the substrate is macroporous.

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.

Abstract: The invention relates to a mixture of diesters of a dicarboxylic acid and isomeric nonanols. Said mixture is selected among a mixture of adipic acid diesters in whose 1H-NMR spectrum, obtained in CDCl3, the rat io of the surface area below the resonance signals in case of chemical shifts of between 1.0 and 2.0 ppm towards TMS to the surface are a below the resonance signals in case of chemical shifts of between 0.5 and 1.0 ppm towards TMS is between 1.20 and 5.00. Alternatively said mixture is selected among a mixture of phthalic acid diesters in whose 1H-NMR spectrum, obtained in CDCl3, the ratio of the surfa ce area below the resonance signals in case of chemical shifts of between 1.1 and 3.0 ppm towards TMS to the surface area below the resonan ce signals in case of chemical shifts of between 0.5 and 1.1 ppm towards TMS is between 1.00 and 4.00. The above adipic and phthalic acid diesters are suitable for use as softeners for moulding materials on a PVC basis and characterized by high compatibility, low brittleness temperature, low stiffness in torsion and/or high thermal stability.
