PROCESS FOR THE PRODUCTION OF ETHYLENE GLYCOL FROM OXALATE. The present invention describes processes for the production of ethylene glycol from an oxalate, where two or more reaction zones, in series, are used, and oxalate as a raw material is fed in stages or hydrogen as a raw material and, optionally, a solvent, which is fed in stages. The processes of the present invention achieve high selectivity for the product and a much longer regeneration period for the catalyst. |
