Abstract:
A continuous process for the preparation of propylene oxide, comprising providing a liquid feed stream comprising propene, hydrogen peroxide, methanol, water, at least one dissolved potassium salt of hydroxyethylidenediphosphonic acid, and optionally propane; passing the liquid feed stream provided in (i) into an epoxidation reactor comprising a catalyst comprising a titanium zeolite of structure type MFI, and subjecting the liquid feed stream to epoxidation reaction conditions in the epoxidation reactor, obtaining a reaction mixture comprising propylene oxide, methanol, water, and the at least one dissolved potassium salt of hydroxyethylidenediphosphonic acid, and optionally propane; removing an effluent stream from the epoxidation reactor, the effluent stream comprising propylene oxide, methanol, water, at least a portion of the at least one potassium salt of hydroxyethylidenediphosphonic acid, and optionally propane.

Claim (Index 7):
The process of  claim 1 , wherein:\n the temperature of the reaction mixture is controlled using a heat transfer medium; the epoxidation reaction conditions comprise an epoxidation reaction temperature ranging from 10 to 100\u00b0 C., wherein the epoxidation reaction temperature is defined as the temperature of the heat transfer medium prior to controlling of the temperature of the reaction mixture; and, the epoxidation reaction conditions comprise an epoxidation reaction pressure ranges from 14 to 100 bar, wherein the epoxidation reaction pressure is defined as the pressure at the exit of the epoxidation reactor.
