Professor James Dumesic

Production of Glycolic Acid from Glyoxal over a Heterogeneous Catalyst

Research Goal

Produce glycolic acid from glyoxal using a heterogeneous catalyst, specifically a Sn-BEA catalyst

Payoff

Develop glycolic acid production process with reduced temperature and pressure requirements and uses a heterogeneous catalyst

Figure 2. Glycolic acid yields over different catalysts.

Approach

Use two glyoxal sources and several catalysts to determine the combination producing the greatest glycolic acid yield.

  • Results
  • Glycolic acid was successfully produced.
  • Sn-BEA catalyst was found to be the most active.
  • Reaction temperature was reduced compared to literature (110°C vs 165°C).
  • Conventional acid catalysts gave lowest yields.
