Abstract
PURPOSE: A resin syrup that has been made to react in a reaction vessel to the level near the end point is made to flow down along the surface of heated wall, thus effecting the final reactions as well as dehydration to produce title solid resin with desired miscibility.
CONSTITUTION: The thin-film reactor is cylindrical and equipped with shaft 6 inside and with liquid-distributing plate 7 on the shaft 6. A resin syrup, for example, a reaction mixture of melamine and formaline at a level near the end point is charged from inlet 11 and supplied onto the liquid-distributing plate 7 that is revolving along with shaft 6, whereby the resin syrup is uniformly distributed on the surface 2 of heated wall in the tower wall by the centrifugal force and flows down along the heated wall surface 2 in thin films. Since the inside of the vessel is kept under reduced pressure, the mixture is dehydrated and extruded out of the bottom wherein the reduced pressure, the heating temperature, the residence time in the vessel, etc., are controlled to permit the final reaction of the melaine resin to the desired miscibility.
