Abstract: There are described novel cyclic phosphorus (III) compounds and a process for the preparation thereof. The phosphorus compounds act as bidentate ligands to form complex compounds with metals, in particular metals of group 8 of the Periodic Table, which complex compounds can be used as constituents of catalyst systems.

Abstract: To prepare higher, predominantly unbranched primary alcohols, olefins obtained in a Fischer-Tropsch synthesis are reacted with hydrogen and carbon monoxide in the presence of water and also rhodium in metallic form or in the form of a compound and in the presence of a water-soluble phosphine as catalyst. The reaction product obtained is hydrogenated. The water-soluble phosphines employed are compounds whose anion is a phosphine containing at least one sulphonated or carboxylated aromatic radical and whose cation is a quaternary ammonium or phosphonium ion.

Abstract: A process for the preparation of methyl carboxylates by the reaction of mono or dicarboxylic acids having more than 5 carbon atoms and methanol in the presence of acidic catalysts at temperatures from 100.degree. to 150.degree.C and below the boiling point of the carboxylates being produced.

Abstract: 6230 Frankfurt, 29.06.1992 PAT/rcht-dbh Hoe92/Y012 Hoechst Aktiengesellschaft, Frankfurt am Main 80 of the disclosure: Mixtures of isomeric decyl alcohols are obtained by oligomerization of propylene in the presence of deactivated zeolites as catalysts, separation of the C9-olefins from the oligomer mixture, hydroformylation of the C9-olefins to C10-aldehydes, and hydrogenation of the C10-aldehydes. The mixtures, when esterified with phthalic acid, provide a mixture of isomeric di-decyl phthalates that can be used as plasticizers.

Abstract: Mixtures of isomeric decyl alcohols are obtained by hydroformylating butadiene to give an aldehyde mixture, condensing the aldehyde mixture which has been separated from the reaction product with the formation of an aldol mixture, and separating off and hydrogenating the aldol mixture. When esterifying the mixture of isomeric decyl alcohols with phthalic acid, a mixture of isomeric decyl phthalates is obtained, and these can be used as plasticisers.
