ZeaChem validates its core biorefining technology

By Gerald Ondrey |

ZeaChem Inc. (Lakewood, Col.; www.zeachem.com today announced it has produced commercial grade ethyl acetate, thereby proving its core technology platform. Ethyl acetate is a widely-used chemical intermediate that can be sold directly to chemical manufacturers or converted into ethanol. The achievement marks the final milestone in proving the core components of the company’s biorefining platform to stakeholders in the fuel and chemicals industries. In February, ZeaChem announced its 10,000 times scale increase in fermentation to acetic acid, and the concentration of that broth into glacial acetic acid, a salable product. Through an esterification reaction process validated externally by process expert Sulzer Chemtech, Ltd. (Winterthur, Switzerland; www.sulzerchemtech.com), the company has converted the glacial acetic acid into ethyl acetate. Both the concentration and esterification processes are commercially available from multiple vendors. "ZeaChem has successfully validated its core biorefining technology from fermentation scale-up to concentration of glacial acetic acid and now ethyl acetate production,” says Jim Imbler, president and CEO of ZeaChem. “These results demonstrate ZeaChem’s ability…
