Abstract

Provided is a tubular flow reactor containing: a cylindrical channel; a mixing shaft which is concentric with the cylindrical channel; and a mixing blade attached to the mixing shaft, wherein the tubular flow reactor satisfy the following requirements: t<2C and t / 2C<A / C≦̸1, provided that C is a radius of the mixing shaft, t is a thickness of the mixing blade; A is a distance between a mixing blade plane B located at a forward position in a rotating direction of the mixing blade and a plane S passing through the center of the mixing shaft in a shaft direction, when plane B and plane S are parallel; and the mixing blade plane B is located at a more forward position in the rotating direction than the plane S.

Description

technical field [0001] The present invention relates to a tubular flow reaction device and a method for producing resin particles using the tubular flow reaction device. Background technique [0002] As a method of industrially producing resin microparticles using emulsion polymerization or suspension polymerization, a method of producing resin microparticles using a batch reaction device or a continuous reaction device is known. [0003] The batch type reactor has problems in that there is a lot of non-production time unrelated to the polymerization reaction, initial equipment investment is increased due to the enlargement of the reactor, and heat transfer capacity is insufficient. [0004] Therefore, a continuous reaction apparatus capable of greatly reducing non-productive time and realizing miniaturization of the apparatus has been adopted. [0005] As a continuous reactor, a tubular flow reactor is disclosed (for example, refer to Patent Documents 1 and 2). [0006] W...
