Process for the production of 2-dimethylaminoethyl (meth)acrylate |
| abstract |
A method for producing 2-dimethylaminoethyl (meth)acrylate by a multistage batch reaction, comprising recycling the catalyst (DBTO) into subsequent reactions, adding a certain amount of fresh catalyst to the recycled catalyst, The catalyst is used in subsequent reactions and wherein the volume reduction due to azeotropic distillation is compensated for by continuous addition of a composition comprising methyl (meth)acrylate and dimethylaminoethanol, thereby maintaining the reactor during the reaction The volume in is constant. |
