Abstract: The method for industrially producing a dialkyl carbonate and a diol, in which the dialkyl carbonate and the diol are continuously produced through a reactive distillation system of taking a cyclic carbonate and an aliphatic monohydric alcohol as starting materials, comprising the steps of: continuously feeding the starting materials into a continuous multi-stage distillation column in which a homogeneous catalyst is present; carrying out reaction and distillation simultaneously in the column; continuously withdrawing a low boiling point reaction mixture containing the produced dialkyl carbonate in a gaseous form from an upper portion of the column; and continuously withdrawing a high boiling point reaction mixture containing the diol in a liquid form from a lower portion of the column, where the method satisfies specific requirements.

Abstract: A method for producing a molded product consisting of a resin polymerized by a melt polycondensation reaction, comprising continuous feeding of a prepolymer in molten state from a prepolymer feeding port to a polymerization reactor, discharging from holes of a porous plate, followed by polymerization while dropping along a supporting substrate under reduced pressure, and molding by transferring to at least one molding machine in molten state without solidification, wherein transfer pressure to said molding machine is controlled so as to maintain at an arbitrary pressure from 0.1 to 100 MPa (absolute pressure).
