摘要 |
<p>The present invention relates to the isolation of a palladium-based catalyst from a mixture in which it is dissolved. More specifically, the invention relates to the isolation of a palladium-based catalyst from a mixture originating from the reaction of hydroxycarbonylation of butadiene to pentenoic acids. It therefore consists of a process for the isolation of at least a portion of the palladium dissolved in a solution also containing at least 3-pentenoic acid, characterized in that the said solution is acidified and stirred with an aqueous solution of hydrochloric acid, so as to obtain two liquid phases including an aqueous phase containing at least a portion of the palladium.</p> |
