摘要:
The invention relates to a method for oxidizing an organic compound containing at least one C-C double bond or a mixture of two or more thereof, comprising the following steps: (I) production of a hydroperoxide; (II) reaction of an organic compound containing at least one C-C double bond or a mixture of two or more thereof with the hydroperoxide produced in step (I) in the presence of a zeolitic catalyst; (III) regeneration of the at least partially deactivated zeolitic catalyst used in step (II) and (IV) reaction according to step (II) using a zeolitic catalyst which contains the regenerated catalyst from step (III).

The invention relates to a method for producing formamide by reacting ammonia and carbon monoxide in the presence of at least one catalyst, said catalyst being sodium diformylamide. Sodium diformylamide can, provided that methanolate is used as an additional active component, be produced therefrom. In the corresponding process, sodium diformylamide is an especially active and stable catalyst which can be recycled.

The invention relates to a method for the production of propylene oxide, whereby (i) propylene is reacted with hydrogen peroxide in the presence of methanol to form propylene oxide, resulting in a mixture (Gi), comprising propylene oxide, methanol, water and unreacted hydrogen peroxide, (ii) from mixture (Gi) a mixture (Gii), comprising methanol, water and hydrogen peroxide is separated off, yielding a mixture (Ga), comprising propylene oxide. Water is separated off from mixture (Gii) to give a mixture (Giii), comprising methanol and methyl formate.

The invention relates to a method for regenerating a zeolite catalyst, comprising the thermal treatment of the catalyst in the presence of a gas stream at temperatures above 120 °C, said gas stream containing hydrogen. The regenerated zeolite catalyst can be used in an integrated method for oxidising an alkene using a hydroperoxide.

The invention relates to a method for the production of propylene oxide in the presence of methanol, during which propylene oxide is separated off from a mixture, comprising propylene oxide and methanol and the resulting mixture comprising methanol is worked up. The invention is characterised in that on working up, methanol is separated from a mixture containing methanol and methyl formate.
