Continuous polymerization of trioxane |
| abstract |
PURPOSE: To continuously polymerize trioxane stably and efficiently, by employing a continuously agitated reactor in which a plurality of pairs of paddles are provided in an axial direction and the reaction mixture is transferred in a specified manner. n CONSTITUTION: A reactor is constructed by (A) providing shafts 1 and 1' in the centers of drums 2 and 2' which are arranged parallel so that they overlap partially with each other, (B) mounting on the shafts 1 and 1' in the longitudinal direction, a plurality of pairs of convex lens-shaped paddles 4 and 4' (these paddles are synchronized so that they rotate while maintaining a slight clearance between a tip of one paddle and the side of another paddle and a clearance between a tip of one paddle and the inner wall of the drum 2) and (C) varying the shape and arrangement of the paddles, so that the transfer efficiency of the reaction mixture decreases gradually with the advancement of the reaction mixture from a material inlet port 5 to a product discharge port 6. The clearance between the tip of a paddle 4 or 4' and the drum 2 is preferably below about 2% of the diameter of the external circle of the paddle, and the clearance between the tip of one paddle and the side of another paddle is preferably below about 5 times the above clearance. n COPYRIGHT: (C)1981,JPO&Japio |
