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: Mixtures of isomeric decyl alcohols are obtained by oligomerisation 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 give C10 aldehydes and hydrogenation of the C10 aldehydes. The mixtures afford, esterified with phthalic acid, a mixture of isomeric didecyl phthalates, which are used as plasticisers.

Abstract: Mixtures of isomeric decyl alcohols are prepared by hydroformylation of mixtures containing but-1-ene and but-2-ene in two stages to give aldehyde mixtures, condensation of the aldehyde mixtures which are separated off and combined with formation of an aldol mixture and separation and hydrogenation of the aldol mixture. The first stage of the hydroformylation is carried out in the presence of rhodium catalysts dissolved in water, the second stage in the presence of cobalt catalysts homogeneously dissolved in the reaction medium. The mixture of isomeric decyl alcohols affords, esterified with phthalic acid, a mixture of isomeric decyl phthalates, which are used as plasticisers.
