PURPOSE:To make it possible to obtain a plurality of reaction products having a plurality of reaction products having different qualities by one reactor, in a reactor with a stirrer, by providing a recessed part to the liquid contact part in the reactor while making the recessed part adjustable from the outside of the reactor. CONSTITUTION:A recessed part 3 is provided to a reactor 1 having a ribbon type stirrer 2. The depth of the recessed part 3 can be regulated by revolving a handle 7 through a screw lever 6 and moving a regulating plate 5 up and down. The recessed part 3 is pref. provided to the liquid contact part of the reactor 1 in the numbers of about 1-4 and pref. has a circular or rectangular shape while the depth (H/D) thereof is set to about 0.01-0.1 and the size (L/D) thereof is set to about 0.1-0.2. By changing the recessed degree of this recessed part 3, the stirring and mixing state in the reactor during reaction can be changed. |
