METHOD FOR THE PRODUCTION OF DECANECARBOXYLIC ACIDS |
摘要 |
The invention relates to a process for preparing a mixture of isomeric decane-carboxylic acids, which comprises the following steps: a) hydroformylation of a hydrocarbon mixture containing linear C4-olefins using a rhodium-containing catalyst system; b) aldol condensation of a mixture of aliphatic C5-aldehydes obtained from step a); c) selective hydrogenation of the mixture of unsaturated C10-aldehydes from step b) to aliphatic C10-aldehydes; d) uncatalysed oxidation of the mixture of aliphatic C10-aldehydes from step c) to give a mixture having a proportion of at least 70% by mass of 2-propylheptanoic acid, based on the total content of isomeric decanecarboxylic acids. |
