Abstract
Provided herein are systems, and methods of using such systems, for producing acrylic acid from ethylene oxide and carbon monoxide on an industrial scale. The production system/production process has various unit operations, including, for example, a β-propiolactone production system/production process configured to produce β-propiolactone from ethylene oxide and carbon monoxide; a polypropiolactone production system/production process configured to produce polypropiolactone from β-propiolactone; and a glacial acrylic acid production system/production process configured to produce acrylic acid with a high purity by thermolysis of polypropiolactone.
