METHOD FOR THE PRODUCTION OF DECANECARBOXYLIC ACIDS.

摘要

The invention relates to a method for producing a mixture of isomeric decanecarboxylic acids, in which the following steps are carried out: a) hydroformylation of a hydrocarbon mixture containing linear C4 olefins using a catalyst system that contains rhodium; b) aldol condensation of a mixture of aliphatic C5 aldehydes obtained in step a); c) selective hydrogenation of the mixture of unsaturated C10 aldehydes from step b) to obtain aliphatic C10 aldehydes; d) uncatalyzed oxidation of the mixture of aliphatic C10 aldehydes from step c) to obtain a mixture containing at least 70 percent by weight of 2-propyl heptanoic acid relative to the total amount of isomeric decanecarboxylic acids.
