- 37 - 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. 26u.inv/jlc
