| 摘要 |
A process is disclosed for making an (ar)alkane carboxylic acid in high yield when reacting an (ar)alkene with a carbonyl compound having at least one hydrogen atom attached to the alpha-carbon atom in the presence of a manganese compound which is at least trivalent by observing the following reaction parameters: (a) having at least 60% by weight of a carboxylic anhydride in the carbonyl compound, (b) having a manganese compound concentration of from 10<->3 to 10<->10 moles/l and (c) maintaining the (ar)alkene concentration below 0.1 mole/l.
