Technology Profile: Bio-acrylic acid production from glucose

This column is based on “Bio-Acrylic Acid Production from Glucose – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/acrylic-acid-production-cost.
Acrylic acid is a moderately strong carboxylic acid, primarily used in the production of emulsion and solution polymers. On a commercial scale, acrylic acid is mainly produced from the oxidation of propylene or propane derived from petroleum or natural gas — both nonrenewable fossil carbon-based starting materials. In recent years, significant research and development efforts have been made toward manufacturing acrylic acid from natural renewable starting materials, such as glucose or molasses originating from biomass, or from glycerol, a byproduct from biofuels production.
The following paragraphs describe bio-based acrylic acid production from glucose syrup, where the glucose is initially fermented to generate 3-hydroxypropionic acid (3-HPA), which is then dehydrated to produce acrylic acid. Figure 1 presents a simplified flow diagram of the process.
