PROCESS FOR PROCESS IMPROVEMENT OF HYDROFORMING IN LIQUID PHASE WITH RECICLING OF RHODIUM CATALYST FOR OBTAINING OF ALDEHIDE

摘要

An improved rhodium catalyzed liquid recycle hydroformylation process, the improvement which comprises selectively separating and recovering phosphorus ligand from the vaporized aldehyde product stream obtained after volatilizing and separating the aldehyde product from the catalyst containing reaction product solution of the hydroformylation process.
