Abstract: A five-axis control machine tool stores rotation-axis data indicating the inclination or runouts of each of a rotation axis A of a tilting table and a rotation axis C of a rotating table in association with rotation angles determined based on NC data, and calculates a correction rotation angle of each of the rotation angles A and C to correct the erroneous attitude of a tool. Five-axis control is performed based on the NC data by rotating the tilting table and the rotating table about the rotation axes A and C at the correction rotation angles, so that a workpiece is machined while eliminating the erroneous attitude of the tool.

Abstract: Reactive distillation equipment applicable to a relatively complicated reaction composed of at least two steps of equilibrium reactions, and a reactive distillation method capable of performing the reaction efficiently. Raw material feeding pipes 5, 6 and 7 are connected to a reactive distillation column 1. The raw material feeding pipes 5, 6 and 7 are disposed on different stages of the reactive distillation column 1 in this order from the top of the column downward. It is preferred that the reactive distillation column 1 includes a stage to which no raw material feeding pipe is connected between a first stage connected to the raw material feeding pipe 5 and a second stage connected to the raw material feeding pipe 6, and between the second stage and a third stage connected to the raw material feeding pipe 7.

Abstract: An aromatic carbonate ester is continuously and efficiently prepared by the transesterification of an aromatic carboxylate with an aliphatic carbonate ester and/or aromatic.aliphatic carbonate ester. A raw material including an aromatic carboxylate, aliphatic carbonate ester and/or aromatic.aliphatic carbonate ester, and a catalyst are continuously fed to a first stage of a reactive distillation column (1) through a raw material feeding pipe (5). Meanwhile, an aliphatic carbonate ester (a) whose boiling point is lower than that of a reactant liquid that is present in a second stage lower than the first stage is continuously fed to the second stage through an aliphatic carbonate ester (a) feeding pipe (6). The second stage is preferably a column bottom section of the reactive distillation column (1). The amount of aliphatic carbonate ester (a) fed is preferably 0.001 to 5 times, by weight, more than the amount of the raw material fed.
