Abstract: Isomeric mixtures of pentanoic acids are prepared by subjecting butene-1/butene-2 mixtures to hydroformylation to form aldehyde mixtures, followed by oxidation of the aldehyde mixtures which have been separated off from the reaction product. The hydroformylation is carried out in a heterogeneous system in the presence of rhodium catalysts which are dissolved in water. The mixture of isomeric 5 carbon monocarboxylic acids produced, when esterified with polyhydric alcohols, yields mixtures of isomeric esters which are useful as lubricants for refrigerant compressors operated with chlorine-free, at least partly fluorinated hydrocarbons as the refrigerant.
