1-Butanol → Butyl Acrylate

Participants

Reaction Steps

A cascade of stirred vessels, consisting of three stirred reactors each having a reaction volume of one liter and equipped with column, condenser and phase separation vessel, was charged with 500 g of the crude acrylic acid discharged from the quench, 570 g of butanol and 13 g of sulfuric acid per hour. The reaction temperature in the reactors was 106° C., 118° C. and 123° C.; the pressure was 700 mbar in each case. At the top of the column a mixture of water, butanol and butyl acrylate was obtained which separated into an aqueous and an organic phase. 300 ppm of phenothiazine were added to the organic phase, which was then passed as a reflux to the column.
