    Abstract: Process for producing 2-(dialkyloxy methyl)-carboxylic acid esters of formula (I) in which: R1 is a non-aromatic hydrocarbon radical or a heterocyclic non-aromatic radical which, besides O, N and/or S atoms, contains only C and H atoms in the ring, with 1 to 20 C atoms, where radical R1 can accept 1 to 5 substituents and the substituents may be the same or different and are halogen, an aryl, carbalkoxy, dialkylamino, diarylamino or cyano group or an alkoxy group, where the alkyl is substituted or unsubstituted C¿1? to C12-alkyl, or an aryloxy group, where the aryl is substituted or unsubstituted C6 to C14-aryl, a substituted or unsubstituted benzyl or phenethyl radical or an R?4O-(R5O)¿x-R5 group, where R4 is substituted or unsubstituted C¿1? to C12-alkyl or C6 to C14-aryl, R?5¿ is a branched or unbranched hydrocarbon radical with 1 to 4 C atoms or phenylene and x = 1 to 6, R2 is hydrogen or alkyl with 1 to 5 C atoms, and R3 is unsubstituted or substituted C¿6? to C14-aryl or a radical listed under R?1¿, by the oxidising β acetalisation of acrylic acid esters with R1OH alcohols, where R1 has the significance given, in the presence of oxygen as the oxidising agent and a catalyst system based on one or more metals of the platinum group and/or their compounds and a copper compound, in which the reaction is conducted at a temperature of up to 80 °C and the catalyst system contains 1 to 4 equivalent anions related to the sum of the metal atoms and cations, of which at most 3 are equivalent halide ions, where the halogen has a molecular weight of at least 35.

    Abstract: A filter material based on a polyarylene thioether having repeating units of the formula -[(Ar1)n-X)]m-[(Ar2)i-Y)]j-[(Ar3)k-Z)]l-[(Ar4)o-W)]p-(I) in which Ar1, Ar2, Ar3, Ar4, W, X, Y and Z, independently of each other, are identical or different, the indices n, m, i, j, k, l, o and p, independently of each other, are zero or integers 1, 2, 3 or 4, their sum being at least 2, Ar1, Ar2, Ar3 and Ar4 are arylene systems having 6 to 18 carbon atoms, and W, X, Y and Z are divalent linking groups, selected from -SO2-, -S-, -SO-, -CO-, -O-, -CO2-, or alkylene groups or alkylidene groups having 1 to 6 carbon atoms is suitable for removing ozone from gases or liquids. The removal proceeds quantitatively, no volatile products being formed.

    Abstract: Process for the preparation of 2-(dialkoxymethyl)carboxylic acid esters of the formula I (I) by oxidizing beta -acetalization of acrylic acid esters with alcohols R1OH, wherein R1 has the meaning mentioned, in the presence of oxygen as the oxidant and of a catalyst system based on one or more metals of the platinum group and/or compounds thereof and of a copper compound, comprises carrying out the reaction at a temperature of up to 80 DEG C. and in which the catalyst system contains 1 to 4 equivalents of anions, based on the sum of the metal atoms and metal cations, of which at most 3 equivalents are halide ions, the halogen having a molecular weight of at least 35.
