  • Patent number: 10329382
    Abstract: Provided is a method to produce an alkylene oxide polymer having a high polymerization degree on an industrial scale and with high reproducibility. The method includes the step of carrying out a polymerization reaction of an alkylene oxide in an inert hydrocarbon solvent in the presence of a zinc catalyst to produce an alkylene oxide polymer. The zinc catalyst is produced by reaction of an organozinc compound with a monohydric alcohol in an amount of 12-fold equivalent or less relative to the amount of the organozinc compound and an aliphatic polyhydric alcohol in an amount of 0.2- to 1.1-fold equivalent relative to the amount of the organozinc compound. The polymerization reaction is carried out under such a condition that the amount of the monohydric alcohol in the polymerization reaction system becomes 0.01-fold equivalent or less relative to the amount of the organozinc compound.

  • Patent number: 8952156
    Abstract: A process is disclosed for separating the output from the reaction of EDDN or EDMN with hydrogen in the presence of THF, a catalyst, TETA or DETA, water, and optionally organic compounds having higher and lower boiling points than TETA or DETA. Hydrogen is removed, and the output is supplied to a distillation column DK1 in which an azeotrope, optionally comprising organic compounds with a boiling point lower than TETA or DETA, is removed from the top. A product comprising TETA or DETA is removed from the bottom and passed into a distillation column DK2, removing THF. A stream comprising TETA or DETA passes from the bottom of DK2. The DK1 azeotrope is condensed. Phase separation is induced by the addition of an organic solvent essentially immiscible with water, and the mixture is separated. The organic phase is recycled into DK1 and the water phase is discharged.
