| titleOfInvention | PROCESS FOR THE PREPARATION OF ETHYLENE GLYCOL BY CATALYTIC HYDROGENATION |
| abstract | THE INVENTION RELATES TO A PROCESS FOR PREPARING ETHYLENE-GLYCOL BY HYDROGENATION OF A MIXTURE OF GLYCOLIC ACID ESTERS. THE LIFETIME OF THE HYDROGENATION CATALYST FOR THE REDUCTION OF A MIXTURE OF GLYCOLATES INTO ETHYLENE-GLYCOL CAN BE EXTENDED BY LOWERING THE CONTENT OF POLYGLYCOLID-TYPE ESTERS IN THE MIXTURE BY TRANSESTERIFICATION, THAT IS, BY HEATING BY PRESERIFICATION. OF AN ALCOHOL AND SUBSEQUENT HYDROGENATION OF THE MIXTURE SO OBTAINED. THUS A GOOD QUALITY PRODUCT IS OBTAINED. |
