    Abstract: Un método para separar acetonitrilo de agua, que comprende (i) proveer una corriente S1 que contiene al menos 95% en peso, con base en el peso total de S1, acetonitrilo y agua, en donde la relación en peso de acetonitrilo:agua es mayor que 1; (ii) agregar a una corriente P, que comprende al menos 95% en peso de C3, con base en el peso total de la corriente P, a S1 para obtener una corriente mixta S2, siendo C3 propeno mezclado opcionalmente con propano con una relación en peso mínima de propeno:propano de 7:3; (iii) someter S2 a una temperatura en el rango de 5 a 90°C y a una presión de al menos 10x105 Pa (10 bar), obteniendo una primera fase líquida L1, en donde al menos 90% en peso de L1 consiste de C3, acetonitrilo y agua, y una segunda fase líquida L2 en donde al menos 90% en peso de L2 consiste de acetonitrilo y agua, y en donde la relación en peso de acetonitrilo:agua en L2 es menor de 1; (iv) separar L1 de L2.

    Abstract: A continuous process for the preparation of propylene oxide, comprising (i) providing a liquid feed stream comprising propene, hydrogen peroxide, acetonitrile, water, optionally propane, and at least one dissolved potassium salt of a phosphorus oxyacid wherein the molar ratio of potassium relative to phosphorus in the at least one potassium salt of a phosphorus oxyacid is in the range of from 0.6 to 1.4; (ii) passing the liquid feed stream provided in (i) into an epoxidation reactor comprising a catalyst comprising a titanium zeolite of structure type MWW comprising zinc, and subjecting the liquid feed stream to epoxidation reaction conditions in the epoxidation reactor, obtaining a reaction mixture comprising propylene oxide, acetonitrile, water, the at least one dissolved potassium salt of a phosphorus oxyacid, optionally propene, and optionally propane; (iii) removing an effluent stream from the epoxidation reactor, the effluent stream comprising propylene oxide, acetonitrile, water, at least a portion of the at least one dissolved potassium salt of a phosphorus oxyacid, optionally propene, and optionally propane.
