Abstract: An improved process for the rhodium-catalyzed hydroformylation of olefins to aldehydes is described. The improvement provides a means for recovering valuable components in gaseous streams by scrubbing the streams with a stripped or cooled catalyst solution.

Abstract: A process for producing acrylic ester by the catalytic esterification of a crude liquid stream of enriched acrylic acid recovered by the partial condensation of the reaction gas effluent from the catalytic oxidation of propylene and/or acrolein. The partial condensation allows a significant proportion of volatile aldehydes and water to pass through the first recovery stage to a second stage for conventional recovery, along with uncondensed acrylic acid vapors and the remainder of the uncondensed reaction gases.
