Abstract: THE PRESENT INVENTION RELATES TO A PROCESS FOR THE GAS-PHASE HYDROGENATION OF C?-DICARBOXYLIC ACIDS AND/OR THEIR DERIVATIVES OVER A CATALYST BASED ON COPPER OXIDE TO GIVE SUBSTITUTED OR UNSUBSTITUTED Y-BUTYROLACTONE AND/OR TETRAHYDROFURAN, WHICH A FIRST REACTION ZONE IN WHICH THE C?-DICARBOXYLIC ACID AND /OR ITS DERIVATIVES IS/ARE REACTED TO GIVE A MIXTURE COMPRISING A SUBSTITUTED OR UNSUBSTITUTED TUTED Y-BUTROLACTONE AS MAIN PRODUCT AND A SUBSEQUENT SECOND REACTION ZONE IN WHICH THE SUBSTITUTED OR UNSUBSTITUTED Y-BUTYROLACTONE PRESENT IN THE MIXTURE FROM THE FIRST HYDROGENATION STEP IS REACTED AT A TEMPERATURE LOWER THAN THE TEMPERATURE IN THE FIRST HYDROGENATION STEP TO GIVE SUBSTITUTED OR UNSUBSTITUTED TETRAHYDROFURAN.
