摘要 |
The present invention provides a method for handling a (meth)acrylic ester-containing solution in which the (meth)acrylic ester-containing solution is treated by at least one process selected from washing, neutralization and extraction, the said method being capable of ensuring a stable continuous operation of the treating system for a long period of time without deteriorating a liquid-liquid separation efficiency and a distillation efficiency in subsequent steps while inhibiting the formation of sludge, when waste water or a waste aqueous solution obtained by recovering effective ingredients from the (meth)acrylic ester-containing solution treated by said at least one process is recycled to the previous process and reused therein. The above waste water or waste aqueous solution is previously cooled to a temperature of 10 to 50°C and then solids are removed therefrom prior to recycling the waste water or waste aqueous solution to the previous process and reusing the same therein. |
