In the operation of producing an alkylamino (meth)acrylatenby the reaction of transesterification of an alkyl(meth)acrylatenwith an alkylamino alcohol, the alkyl alcohol by-produced duringnthe transesterification is distilled in the form of an azeotropicnmixture with the alkyl(meth)acrylate, the resultant distillate isnpurified with an ion-exchange resin and handled, on the other hand,nthe reaction solution is distilled to allow separation of thencatalyst wherein is provided a method and apparatus for effecting,nin the production of the alkylamino (meth)acrylate, thendistillation under such a condition as represses the amount ofnincrease of the Michael adduct below 2%. |
