    Abstract: A PROCESS IS DESCRIBED FOR CONTINUOUSLY PREPARING ALKYL ESTERS OF (METH)ACRYLIC ACID BY REACTING (METH)ACRYLIC ACID AND ALKANOLS HAVING FROM 1 TO 5 CARBON ATOMS IN HOMOGENEOUS, LIQUID, SOLVENT-FREE PHASE AT ELEVATED TEMPERATURE AND IN THE PRESENCE OF AN ACIDIC ESTERIFICATION CATALYST, IN WHICH - THE (METH) ACRYLIC ACID, THE ALKANOL AND THE ACIDIC ESTERIFICATION CATALYST ARE FED TO A REACTION ZONE (5, 6), - A REACTION MIXTURE (21) IS DISCHARGED FROM THE REACTION ZONE (5: 6). AND IS INTRODUCED INTO A RECTIFICATION UNIT I AND SEPARATED BY ADDITION OF WATER INTO A TOP STREAM (23), COMPRISING THE ALKYL ESTER OF (METH)ACRYLIC ACID, AND A BOTTOM STREAM (22), AND - A SUBSTREAM OF THE BOTTOM STREAM (22) FROM THE RECTIFICATION UNIT I IS FED TO A RESIDUE DISSOCIATION UNIT IV, WHICH COMPRISES A DISSOCIATING BOILER (61). AND IS SEPARATED THEREIN INTO A TOP STREAM (29), WHICH IS RECYCLED INTO THE RECTIFICATION UNIT I AND A BOTTOM STREAM (40). WHICH IS REMOVED FROM THE SYSTEM, WHEREIN THE RESIDUE DISSOCIATION UNIT IV, AS WELL AS THE DISSOCIATING BOILER (61), FURTHER COMPRISES A RECTIFICATION COLUMN (62), THE WATER CONTENT OF THE LIQUID OBTAINED AT THE BOTTOMMOST STAGE THEREOF BEING LESS THAN 0.1% BY WEIGHT.
