    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 ratio of the surfa ce area below the resonance signals in case of chemical shifts of between 1.0 a nd 2.0 ppm towards TMS to the surface area 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 aci d 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 a nd 3.0 ppm towards TMS to the surface area below the resonance 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.

    Abstract: The process for operating a purification apparatus for gases comprises passing the gas stream through a filter body containing a catalyst and catalytically converting the pollutants. At low temperature, especially below 200 degrees C, more especially below 150 degrees C, hydrocarbons are stored in the filter body (2) and released above these temperatures, and pollutants are catalytically converted with the aid of the carrier material of the filter body. Also claimed is the purification apparatus consisting of a filter body (2) made from a carrier material which stores at least 20 vol.%, preferably at least 50 vol.% of the hydrocarbons at below 200 degrees C, especially below 150 degrees C. The carrier material effectively reduces the pollutants with the aid of a reductant, preferably hydrocarbons and/or carbon monoxide.

    Abstract: A process is disclosed for reducing Nox in which x equals 1 or 2, from exhaust fumes on heterogeneous catalysts with hydrocarbons, carbon monoxide, hydrogen or their mixtures, in the presence of oxygen, at a temperature from 100 to 650 DEG C and an absolute pressure of 0.5 to 50 bars. As heterogeneous catalysts, bimodal or higher-modal compounds are used which have the general formula (I) A1-x M2 O4 and are optionally doped with rare earths, precious metals, titanium, vanadium, molybdenum, tungsten or their mixtures. In the formula (I), A stands for magnesium, calcium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, tin or their mixtures; M stands for aluminium, gallium, indium, tin, chromium, manganese, iron, cobalt, nickel, copper, zinc or their mixtures; and x equals 0 to 0.99. The oxygen atoms of said compounds are arranged in the densest possible cubic sphere packing in which A is located in the tetrahedral gaps and M in the octahedral gaps, wherein A may also occupy octahedral gaps when an equivalent amount of M occupies tetrahedral gaps.

    Abstract: Catalyst containing metallic oxides, which in addition to oxides of titanium and/or zirconium, oxides of vanadium and/or niobium and oxides of molybdenum, tungsten and/or chromium, also contains sulphates of the alkaline earth metals, and which is used in a process for the oxidative breakdown of organic compounds in the waste gases from incinerator plants.
