Abstract: The invention relates to a method for the production of phthalic anhydride to a specification, using a distillative purification of crude phthalic anhydride, by introduction of crude phthalic anhydride into a distillation column, operating at reduced pressure, withdrawal of the low-boiling fraction from the head, or near the head of the column and withdrawal of the phthalic anhydride, which meets the specification, from a side-tap on the column, whilst operating the column at a reflux ratio x, with 1:1.7

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.

Abstract: The invention relates to polyesters that are appropriate as softeners and that are obtainable by reacting aliphatic dicarboxylic acids, neopentylglycol, at least one further diol and a nonanol mixture. Said nonanol mixture substantially consists of 1-nonanol, monomethyl octanols, dimethyl heptanols and monoethyl heptanols. The invention further relates to the nonanol mixture and to the use of the inventive polyesters as softeners.

Abstract: The invention relates to a method for producing esters of an acid component chosen from the multibasic C4-C10-carboxylic acids and an alcohol component chosen from C3-C12-alkanols or -alkanediols whose alkyl chain can be interrupted by 1 to 3 oxygen atoms. Sad method comprises the following steps: a) a mixture consisting essentially of the acid component or an anhydride thereof and the alcohol component is heated to boiling in a reaction zone in the presence of an esterification catalyst; b) the vapours containing alcohol and water are separated into a fragment that is rich in alcohol and a fragment that is rich in water by rectification; and c) the alcohol-rich fraction is fed back into the reaction zone, while the water-rich fraction is extracted from the process. The inventive method is simple to carry out and allows the rapid adjustment of an essentially quantitative conversion.

Abstract: New mixtures (I) of dicarboxylic acid diesters with isomeric nonanols consist of adipate or phthalate diester mixtures having 1H-NMR spectra (obtained in CDCl3) with specific ratios of surface areas below the resonance signals for particular chemical shifts towards TMS. The ratio of the surface area for shifts of 1.0-2.0 ppm to that for shifts of 0.5-1.0 ppm is 1.20-5.00 for the adipate diesters; and the ratio of the surface area for shifts of 1.1-3.0 ppm to that for shifts of 0.5-1.1 ppm is 1.00-4.00 for the phthalate diesters; An Independent claim is included for mixtures (II) of isomeric nonanols which either: (i) form (I) as defined above on esterification with adipic or phthalic acid; or (ii) are obtained by hydroformylation of a mixture of isomeric octenes in presence of a cobalt catalyst and hydrogenation of the product, where the isomeric octene mixture is obtained by contacting a hydrocarbon mixture containing butenes with a heterogeneous catalyst containing a nickel oxide.
