| titleOfInvention | Process for preparing alkyl methacrylate |
| abstract | The present invention relates to a method for preparing alkyl (meth) acrylate, and more particularly, esterifying a reactant including (meth) acrylic acid and an alkanol at a conversion rate of 70% or more in the presence of an organic acid catalyst; Supplying and purifying the reaction product of the esterification reaction to a distillation column having a heat flow reboiler at the bottom; Recovering an upper effluent including alkyl (meth) acrylate and water in the upper part of the distillation column, and recovering a lower effluent including high boiling point adduct and water in the lower part of the distillation column; Separating the bottom discharge liquid of the distillation column into a water layer and an organic layer; And recycling the water layer separated from the bottom effluent for use in the esterification reaction, wherein each step occurs continuously, and the water contained in the bottom effluent of the distillation column is added to the total weight of the effluent. It relates to a method for producing an alkyl (meth) acrylate with respect to 2 to 25% by weight relative to. The method for preparing alkyl (meth) acrylate according to the present invention, while having a high recovery and reuse rate of the catalyst, can secure the fluidity in the high-boiling addition product decomposition reactor to prevent pipe blockage, and finally There is an advantage to reduce the amount. |
