Abstract: METHYL METHACRYLATE IS REACTED UNDER REFLUXING CONDITIONS WITH A DIALKYLAMINOETHANOL IN THE PRESENCE OF A CATALYST, SUCH AS SODIUM METHOXIDE, AND IN THE PRESENCE OF AN ENTRAINER WHICH, FOR EXAMPLE, IS BENZENE, THE METHONAOL-BENZENE AZEOTROPE, WHICH IS TAKEN OFF OVERHEAD FROM THE REACTION ZONE, IS CONDENSED AND THE RESULTING LIQUID COMPOSITION IS PASSED THROUGH A MOLECULAR SIEVE BED FOR REMOVAL OF THE METHANOL THE BENZENE EFFLUENT FREE OF METHNOL, WITHDRAWN FROM THE SEIVE BED IS RECYCLED TO THE REACTOR, A PRODUCT STREAM REMOVED FROM THE REACTOR CONTAINING THE DIALKYLAMINOETHYL METHACRYLATE PRODUCT TOGETHER WITH UNREACTED DIALKYLAMINOETHANOL, METHYL METHACRYLATE, CATALYST AND INHIBITOR IS SENT TO A DISTILLATION AREA SUCH AS A DISTILLATION TOWER, OR SERIES THEREOF, FOR RECOVERY OF THE PRODUCT AND THE UNREACTED STARTING MATERIALS IE., THE DIALKYLAMINOETHANOL AND THE METHYL METHACRYLATE, WHICH ARE RECYCLED TO THE REACTION ZONE.
