ABSTRACT:
In the preparation of a carboxylic acid by the carbonylation of an olefin in the presence of hydrofluoric acid catalyst, the hydrofluoric acid is isolated from the carboxylic acid by means of an ion-permeable membrane and the thus-isolated hydrofluoric acid can be recycled to again catalyze the carbonylation reaction.
