PROCESS FOR THE PRODUCTION OF N-ALKYLAMINOALKYL (METH)ACRYLATES |
摘要 |
<p>The present invention is to provide a method of producing an N-alkylaminoalkyl (meth)acrylate containing a small amount of low boiling components, especially, containing a small amount of raw components, without any complicated operations or special apparatuses. The method of producing an N-alkylaminoalkyl (meth)acrylate comprising the steps of: (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 the step of: (D) adjusting water concentration at a range from 0.01 to 1 wt%. in the reaction solution which is located after the step (A) and before the step (C).</p> |
