Abstract:
A continuous process for the preparation of propylene oxide, comprising a start-up stage and normal run stage, wherein the normal run stage comprises (i) continuously providing a liquid feed stream comprising propene, hydrogen peroxide, acetonitrile, a formate salt, water and optionally propane, wherein in the liquid feed stream, the molar amount of the formate salt relative to the molar amount of hydrogen peroxide at a given point of time during the normal run stage is a N (Fo/H 2 O 2 ); (ii) continuously passing the liquid feed stream provided in (i) into an epoxidation zone comprising a catalyst comprising a titanium zeolite having framework type MWW, and subjecting the liquid feed stream to epoxidation reaction conditions in the epoxidation zone, obtaining a reaction mixture comprising propylene oxide, acetonitrile, water, the formate salt, optionally propene, and optionally propane; (iii) continuously removing an effluent stream from the epoxidation zone, the effluent stream comprising propylene oxide, acetonitrile, water, at least a portion of the formate salt, optionally propene, and optionally propane; wherein the normal run stage is characterized in an average rate of change of a N (Fo/H 2 O 2 ) of less than 0 h −1 .

Claim (Index 7):
The continuous process of  claim 1 , wherein:\n during the normal run stage, the epoxidation conditions according to (ii) comprise a hydrogen peroxide conversion c N (H 2 O 2 ); the average rate of change of c N (H 2 O 2 ) ranges from \u22121.0*10 \u22123  to 1.0*10 \u22123 %-points*h \u2212 ; and c N (H 2 O 2 ) is defined as the molar amount of hydrogen peroxide comprised in the effluent stream removed in (iii) relative to the molar amount of hydrogen peroxide comprised in the liquid feed stream provided in (i) at a given point of time during the normal run stage.
