Verfahren zur Herstellung von Alkylamino-(meth)Acrylat und eine Vorrichtung dafür

摘要

In the operation of producing an alkylamino (meth)acrylate by the reaction of transesterification of an alkyl(meth)acrylate with an alkylamino alcohol, the alkyl alcohol by-produced during the transesterification is distilled in the form of an azeotropic mixture with the alkyl(meth)acrylate, the resultant distillate is purified with an ion-exchange resin and handled, on the other hand, the reaction solution is distilled to allow separation of the catalyst wherein is provided a method and apparatus for effecting, in the production of the alkylamino (meth)acrylate, the distillation under such a condition as represses the amount of increase of the Michael adduct below 2%.
