An apparatus for reaction according to the present invention includes a horizontal-type reactor having first and second portions and a liquid circulator for circulatorily feeding a liquid from the first portion of the reactor, through the second portion of the reactor which is spaced apart from the first portion of the reactor in the direction of axis of the reactor. The reactor includes stirring blades on a stirring shaft whereby the liquid can be stirred in the rotational directions of the stirring blades of the horizontal-type reactor, while it is stirred in the axial direction thereof by the liquid circulator, thereby enabling the liquid to be stirred uniformly throughout the interior of the reacting apparatus without damaging surface renewal effects on a vapor-liquid interface.

The present invention comprises a pair of agitator blades which have a plurality of annular members connected to each other and which are provided in parallel in a cylindrical vessel body, the agitator blades being held so that the edges of one of the agitator blades enter the rotational region of the other agitator blade and pass therethrough. Consequently, the invention prevents liquid to be treated from adhering to and rotating together with rotational shafts and the agitator blades and deterioration in product quality due to scaling so as to enable the continuous treatment of a highly viscous material.
