摘要： Provided is a continuous stirred tank reactor for an aldol condensation reaction and an apparatus for an aldol condensation reaction including the same, which prevent a decrease in a conversion rate due to dead zone occurrence even in the case of an increase of an installation scale, have a high output, have a significantly increased reaction surface area during the reaction, suppress layer separation between an aqueous phase and an organic phase, and have a significantly decreased average particle diameter of organic layer particles dispersed in the aqueous phase and a significantly decreased deviation thereof. In addition, a content of the catalyst used per unit yield may be significantly decreased as compared with the conventional reactor and apparatus, and costs required for wastewater treatment may be significantly reduced as compared with the conventional reactor and apparatus.

摘要： Provided is an apparatus for an aldol condensation reaction having high productivity at low cost. Specifically, the apparatus for an aldol condensation reaction according to the present invention has an effect of having high productivity by preventing a drop in a conversion rate due to an increase in a residence time when increasing a facility scale, allows conditions of raising a concentration of a catalyst and a temperature, and has an effect of minimizing a content of the catalyst used at the same yield as compared with a conventional apparatus. In addition, costs required for increasing a facility scale may be minimized without adding a device such as a pump separately, and an amount of harmful wastewater produced may be minimized.
