Ethylene Glycol from Synthesis Gas
Published: January 1975
A rhodium-catalyzed process developed by Union Carbide for the one-step conversion of CO + H2 synthesis gas to ethylene glycol appears potentially cheaper than ethylene-based glycol syntheses.
A process formerly used by Du Pont for making glycol from synthesis gas via methanol, formaldehyde, and glycolic acid could be competitive with the conventional ethylene oxide route at the high ethylene prices.
