Process for the epoxidation of an olefin with improved energy balance

The present invention relates to a continuous process for the preparation of an olefin oxide wherein an olefin is reacted with a hydroperoxidein the presence of a catalyst, and wherein the reaction which is carried out in at least three reactors operated in parallel is controlled by specifically adjusting the catalyst loads in the reactors.

Process for the preparation of an olefin oxide

The present invention provides a process for the epoxidation of propene which comprises reacting propene with hydrogen peroxide in the presence of methanol as solvent and a titanium zeolite catalyst, the process further comprising separating propylene oxide from the reaction mixture to obtain a mixture comprising methanol, water, at least one carboxylic acid and at least one carbonyl compound, wherein the at least one carboxylic acid is at least partially neutralized, said process optionally comprising a hydrogenation stage.

Process for epoxidizing propene

A method of separating propylene oxide from a mixture (M) comprising propylene oxide and methanol, said method comprising: (i) introducing said mixture (M) into an extractive distillation column; (ii) additionally introducing an extracting solvent into said extractive distillation column; (iii) distilling propylene oxide overhead from said extractive distillation column as top stream; (iv) withdrawing a bottoms stream from said extractive distillation column; (v) compressing the top stream obtained overhead in (iii) by means of at least one compressor to give a compressed vapor.

Separation of propylene oxide from a mixture comprising propylene oxide and methanol

A method of separating propylene oxide from a mixture (M) comprising 5 to 50 percent by weight propylene oxide and 50 to 85 percent by weight methanol, said method comprising

The present invention relates to a method of separating an olefin from a gas stream, said gas stream comprising the olefin and at least one other component, said method comprising
