Abstract
Abstract 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.
