    摘要： The invention provides a process for producing dialkanolamines through amination of alkylene oxide with ammonia at liquid phase, in which side formation of trialkanolamines is inhibited and dialkanolamines can be produced with high selectivity and high efficiency. Said process is carried out in the presence of a catalyst which possesses such reaction characteristics that render the rate constant &agr; of the reaction between ammonia and alkylene oxide not less than 0.10, when the reaction rate constant between monoalkanolamine and alkylene oxide is 1, and the rate constant &bgr; of the reaction between dialkanolamine and alkylene oxide not more than 0.7, when the reaction rate constant between monoalkanolamine and alkylene oxide is 1.

    摘要： Selective production of a dialkanolamine is attained by controlling the volume preceding the entrance to a catalyst bed and the temperature prevailing under respectively fixed levels subsequent. to the mixture of an alkylene oxide thereby repressing a reaction occurring in the absence of a catalyst and curbing the formation of trialkanolamine. The reactant fluid is prevented from generating a channeling by disposing an exportable structure in a reactor thereby creating the state of a false shell-and-tube type reactor. The reaction is initiated with the inlet temperature set at a higher level than the prescribed level and the alkylene oxide concentration set at a lower level than the prescribed level and thereafter the inlet temperature and the alkylene oxide concentration are gradually changed toward the respectively prescribed levels.

    摘要： 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. By feeding raw material (A), raw material (B) and raw material (E) from the raw material feeding pipes 5, 6 and 7, respectively, vapor-liquid contacting of raw materials (A) and (B), and vapor-liquid contacting of product (C) and raw material (E) are carried out.
