1. A method for producing acrylic acid, comprising:

  • contacting ethylene oxide with carbon monoxide in the presence of a metal carbonyl compound supported on a solid support in a first reaction zone;

    carbonylating at least a portion of the ethylene oxide in the first reaction zone to produce beta-propiolactone;

    directing the beta-propiolactone to a second reaction zone; and

    converting at least a portion of the beta-propiolactone in the second reaction zone to acrylic acid in the presence of a catalyst, wherein the conversion of the beta-propiolactone to the acrylic acid is performed in a continuous flow format.
