    Abstract: omega -Formylalkanecarboxylic esters are prepared by hydroformylation of alkenecarboxylic esters with carbon monoxide and hydrogen at elevated temperature and under elevated pressure in the presence of cobalt carbonyl complexes, in which alpha , beta -unsaturated alkenecarboxylic esters are hydroformylated in the presence of 0.01 to 1 mol% of cobalt carbonyl complexes, calculated as cobalt, while maintaining a conversion of alpha , beta -unsaturated alkenecarboxylic esters of 10 to 70 %.

    Abstract: Microcapsules containing a bleaching assistant obtained by polymerisation of a monomer mixture comprising (total monomer mixture = 100 wt. %) (a) 5-100 wt. % of at least one ethylenically unsaturated carboxylic acid anhydride, (b) 0-95 wt. % of at least one monoethylenically unsaturated monomer different to monomer group (a), (c) 0-80 wt. % crosslinking monomers having at least two non-conjugated monoethylenically unsaturated groups in the molecule and (d) 0-20 wt. % water soluble monoethylenically unsaturated monomers, in the oil phase of a stable oil-in-water emulsion in the presence of radical forming polymerisation initiators, and optionally continuously or periodically increasing the temperature of the polymerisation reaction mixture during the polymerisation are new. The oil phase of the emulsion contains or consists of the bleaching assistant. Also claimed are washing and cleaning agents containing the encapsulated bleaching agent assistants for the cleaning of textile s.

    Abstract: 1,1,2-Trialkoxyethanes of the general formula I (I) where R1 to R3 are each independently of the others C1-C20-alkyl or cycloalkyl, or R1 and R2 may be linked together to form a 5-, 6- or 7-membered ring, are prepared by reacting formaldehyde dialkyl acetals of the general formula II (II) where R1 and R2 are each as defined above, or compounds which are capable of forming formaldehyde dialkyl acetals under the reaction conditions, with carbon monoxide, hydrogen and alkanols R3OH under superatmospheric pressure at elevated temperature in the presence of a catalyst composed of a cobalt carbonyl compound and a promotor, wherein the promotor is an alkali metal, alkaline earth metal or ammonium salt of a protogenic compound having an acid constant Ka of from 10-2 to 10-14, an alkali metal or alkaline earth metal hydroxide or an aminocarboxylic acid.
