PROCESS FOR THE PREPARATION OF ETHYLENE GLYCOL FROM AQUEOUS SOLUTION OF ETHYLENE OXIDE BY EXTRACTION WITH CARBON DIOXIDE AND HYDROLYSIS

摘要

PREPARATORY METHOD OF ETHYLENE GLYCOL FROM AQUEOUS SOLUTION OF ETHYLENE OXIDE BY EXTRACTION WITH CARBON DIOXIDE AND HYDROLYSIS. EXTRACT OF ETHYLENE OXIDE FROM AN AQUEOUS SOLUTION USING A CARBON DIOXIDE OF ABOUT 12 OR SUPER-CRITICISM, THEN THE ETHYLENECOACEOUS OXIDE MIXTURE IS IN CONTACT WITH A CATALYST 22 TO FORM 20 OF ETHYLENE CARBON 24 WHICH IS HYDROLYSIS 26 IN ETHYLENE GLYCOL IN THE PRESENCE OF THE SAME CATALYST. ETHYLENE GLYCOL IS SEPARATED AS A PRODUCT, AND CO 2 AND CATALYST 36 RECYCLED.
