摘要： In a first aspect, the present invention relates to a shutdown method for a process for preparing an olefin oxide comprising a normal run stage, wherein the normal run stage comprises providing olefin, hydrogen peroxide and organic solvent into an epoxidation zone comprising an heterogeneous epoxidation catalyst, so that a reaction mixture comprising olefin, hydrogen peroxide and organic solvent is formed and subjecting the reaction mixture to epoxidation reaction conditions in the epoxidation zone, thereby obtaining a mixture comprising olefin oxide and organic solvent; wherein the shutdown method comprises (a) providing olefin and organic solvent for a period of time t1 to the epoxidation zone, so that a mixture is formed, which is essentially free of hydrogen peroxide; (b) contacting the mixture from (a) over t1 under epoxidation reaction conditions in the epoxidation zone with the heterogeneous epoxidation catalyst; (c) removing during t1 an effluent stream from the epoxidation zone, the effluent stream comprising olefin and organic solvent. In a second aspect, the present invention relates to a process for preparing an olefin oxide comprising a normal run stage and a shutdown stage, wherein the normal run stage comprises (A) providing olefin, hydrogen peroxide, water and organic solvent into an epoxidation zone comprising an heterogeneous epoxidation catalyst, so that a reaction mixture comprising olefin, hydrogen peroxide, water and organic solvent is formed; (B) subjecting the reaction mixture from (I) to epoxidation reaction conditions in the epoxidation zone, thereby obtaining a mixture comprising olefin oxide, water and organic solvent; (C) removing an effluent stream from the epoxidation zone, comprising olefin oxide, water and organic solvent; wherein the shutdown stage comprises steps (a), (b) and (c) as described with respect to the first aspect.

摘要： A process for making propene oxide involves reacting propene with hydrogen peroxide in the presence of methanol, a titanium zeolite epoxidation catalyst, and nitrogen containing compounds present in an amount of from 100 to 3000 mg/kg of hydrogen peroxide. Non-reacted propene is separated from the reaction mixture; the propene depleted reaction mixture Is continuously distilled in a distillation column providing an overhead product stream containing propene oxide and methanol and a bottoms product stream; and propene oxide is separated from the overhead product stream. An acid is added to the propane depleted reaction mixture and/or to the distillation column at the same level or above the feed point for the propene depleted reaction mixture and/or contacted to the feed to the distillation column to provide an apparent pH in the bottoms product stream of from 3 to 4.5, which reduces the nitrogen content of the separated propene oxide.

摘要： The present invention discloses a monoepoxy compound represented by the following Formula (1), a curable composition containing the same, a cured product therefrom, a method of producing the monoepoxy compound, and a reactive diluent containing the monoepoxy compound. The monoepoxy compound represented by the Formula (1) is useful in that it is capable of reducing the viscosity of a curable composition containing the monoepoxy compound, while preventing a reduction in the heat resistance of the curable composition as well as a reduction in the weight of the curable composition upon curing. (In the Formula (1), R1 to R6 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, and an alkoxy group.)
