摘要： The present disclosure relates to a method for effecting catalytic selective oxidation in liquid phase comprising a perfluorinated solvent and an olefinic compound with molecular oxygen to produce an epoxide. The method may provide enhanced selectivity to the epoxide of greater than 60%. The olefinic compound may be ethylene, propylene, butenes, 1-octene, butadiene, allyl chloride, allyl alcohol, styrene, and the like. The perfluorinated solvent may be perfluoro methyldecalin, perfluorodecalin, perfluoroperhydrophenanthrene, perfluoro (butyltetrahydrofuran), isomers thereof, or a combination thereof. In some embodiments, the method includes catalytically epoxidizing, in a liquid phase comprising a perfluorinated solvent, propylene with molecular oxygen to produce propylene oxide. A system for carrying out the method is also provided, the system comprising a source of a perfluorinated solvent, and a liquid phase reactor fluidly connected with the source, and configured for effecting catalytic selective oxidation, in a liquid phase comprising the perfluorinated solvent, of an olefinic compound with molecular oxygen to produce an epoxide.

摘要： A method including contacting an organic stream with water and carbon dioxide, whereby sodium is extracted from the organic stream, and separating an aqueous sodium salt-containing phase from an organic phase comprising a reduced sodium content. The organic stream can be a heavy residue formed in the co-production of propylene oxide and styrene. Contacting can include combining the carbon dioxide with the water to form a CO2-saturated water stream and contacting the CO2-saturated water stream with the organic stream, and/or combining the organic stream and the water to form a mixture and injecting the carbon dioxide as a gas thereinto. The method can further include repeating the contacting and the separating one or more times on the organic phase, subjecting the organic phase to ion exchange, or both, to obtain an organic phase having a further reduced sodium content. A system for carrying out the method is also provided.

摘要： The present disclosure relates to a method including subjecting an organic stream comprising at least one oxygenate to hydrotreatment, whereby a hydrotreatment product comprising ethylbenzene is produced, wherein the organic stream is a product of a process for the production of propylene oxide; and separating an ethylbenzene product stream from the hydrotreatment product, to yield a residual stream.
