Patent ID: 7411086

Claim:
A method of producing an N-alkylaminoalkyl (meth)acrylate by a reaction between a (meth)acrylic acid ester and an N-alkylaminoalkyl alcohol, comprising: (A) performing the reaction between the (meth)acrylic acid ester and the N-alkylaminoalkyl alcohol in a presence of a catalyst to obtain a reaction solution containing the N-alkylaminoalkyl (meth)acrylate; (B) distilling out components which have lower boiling points than the N-alkylaminoalkyl (meth)acrylate from the reaction solution obtained by the step (A); and (C) distilling the N-alkylaminoalkyl (meth)acrylate; and further comprising: (D) adjusting a water concentration at a range from 0.01 to 1 wt % in the reaction solution by introducing water into the reaction solution which is located after the step (A) and before the step (B).
