Synthesis of precursors to ethylene glycol from
The DuPont process for MEG synthesis via formaldehyde carbonylation achieved yields in excess of 96% using H2SO4 as the catalyst [10,11]. The reaction required 900atm of CO pressure and temperatures between 150 and 200 C. All reactants in the DuPont process were prepared from coalderived syngas. Corrosive reac
