    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: A process for the preparation of phosphabenzene compounds of the formulae I and IIwhere R1 to R6, independently of one another, are hydrogen, COOM SO3M, NR3X, NR2, OR, COOR or SR, where M is hydrogen, NH4 or an alkali metal, X is an anion, R is hydrogen, C1-6-alkyl, or C1-12-alkyl, C6-12-aryl, C7-12-aralkyl or C3-6-heterocycloalkyl having 1 to 3 heteroatoms which may be substituted by the above radicals or linked to form fused rings, and-W- is a bridge comprising a covalent bond, an oxo group, a sulfur group, an amino group, a di-C1-6-alkylsilicon group or a C1-16-radial, which may be part of one or more linked cyclic or aromatic rings and may be interrupted by 1 to 3 heteroatoms, where the phosphabenzene ring o- or m-position not bonded to the bridge may carry one of the radicals R1 to R6,with the exception of bis-3,3'-(2,4,6-triphenyl-3-phosphabenzene)-1,1-biphenyl, by reacting corresponding pyrilium salts with PH3 in the presence of a catalytic amount of acid and in the presence or absence of a solvent or diluent, where the pyrilium salts are mixed with PH3 at above 0° C. and reacted at from 0° C. to 200° C. and at a pressure greater than 1 bar.

    Abstract: Preparation of hydantoins or aminoacid cyclic anhydrides (I) involves reacting an aldehyde (II) with carbon monoxide and a u or carbamate compound (III) in presence of a transition metal catalyst. Preparation of hydantoins or aminoacid cyclic anhydrides of formula (I) involves reacting an aldehyde RCHO (II) with carbon monoxide and a urea or carbamate compound of formula R3-NH-C(O)-R2 (III) in presence of a transition metal catalyst. X = O or NH; R = alkyl or aryl (both optionally substituted); R3 = H or as defined for R; R2 = group which reacts with the COOH group formed in the reaction under ring-closure to form (I).

    Extraction of metal-complex catalyst enriched stream comprises dissolving e.g. reaction products in reaction medium, distillating catalyst free stream of discharge, and separating high boiling and non-distilled components of discharge

    Abstract: Extraction of a metal-complex catalyst enriched stream comprises dissolving e.g. reaction products and by-products, in a reaction medium by an agent containing phosphorous and/or nitrogen atoms, modified organic metal complex catalyst; distillating the catalyst free stream of the reaction discharge; separating high boiling and non-distilled components of the reaction discharge and the sump product of the distillation into a permeate- and retentate- stream and recycling the retentate stream enriched, completely or partially into the metal-complex-catalyst. Extraction of a metal-complex catalyst enriched streams, obtained from the liquid discharge of a metal complex catalyst reaction comprises dissolving reaction products, by-products, non-converted educt, solvent, homogeneous or colloid in a reaction medium by an agent containing one or more phosphorous and/or nitrogen atoms, modified organic metal complex catalyst with a molecular weight of greater than 200 D and free ligands; distillating the catalyst free stream containing low boiling components of the reaction discharge at atmospheric pressure or low pressure; separating high boiling and non-distilled components of the reaction discharge and the sump product of the distillation into a permeate- and retentate- stream, by a membrane-separator device and recycling the retentate stream enriched with the metal-complex catalyst, completely or partially into the metal-complex-catalyst.
