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.

Process for producing acrylic ester

A process for the gas phase hydrogenation of unsaturated trisubstituted monoesters to the saturated trisubstituted alcohols using a Zn.sub.a Cu.sub.b X.sub.c Ni.sub.d O.sub.e reduced catalyst.

Process for the production of saturated neo-alcohols

A method of producing substantially pure dialkyl maleate by separating monoalkyl maleate from dialkyl maleate in a short residence time distillation zone while minimizing reversion of the monoalkyl maleate to alkanol and maleic anhydride and without having to neutralize the monoalkyl maleate.
