1. A method for the synthesis of acrylic acid comprising the steps of:

  • providing a gaseous feedstock stream comprising ethylene oxide and carbon monoxide;

    directing the feedstock stream to a first reaction zone where it is contacted with a metal carbonyl compound and where at least a portion of the ethylene oxide is converted to a carbonylation product stream comprising beta propiolactone;

    directing the carbonylation product stream to a second reaction zone where it is contacted with a catalyst, which catalyzes the conversion of beta propiolactone to acrylic acid, wherein the conversion of beta propiolactone to acrylic acid is performed in a continuous flow format;

    withdrawing an acrylic acid product stream from the second reaction zone; and

    isolating acrylic acid from the product stream.
