Abstract

Se purifica óxido de propeno mediante destilación extractiva, alimentando óxido de propeno crudo que comprende entre 15 y 97% en peso de óxido de propeno, entre 2 y 84% en peso de metanol, y acetaldehído a un punto de alimentación A en la sección del medio de una columna de destilación extractiva; alimentando un solvente acuoso de extracción a un punto de alimentación B situado por encima del punto de alimentación A; y alimentando un compuesto reactivo de estructura R¹-Y-NH₂, donde Y es oxígeno o NR² y R¹ y R² son independientemente entre sí hidrógeno, un grupo alquilo o un grupo arilo, o una sal de dicho compuesto reactivo, al punto de alimentación B, punto de alimentación A o entre los puntos de alimentación A y B; retirando una corriente S1 de la parte superior de la columna de destilación extractiva para proporcionar un primer producto de óxido de propeno que contiene menos de 200 ppm de agua; y retirando una corriente S2 en un punto de remoción 5 a 25 etapas de separación teóricas por encima del punto de alimentación B para proporcionar un segundo producto de óxido de propeno que contiene entre 500 y 10000 ppm de agua.Propene oxide is purified by extractive distillation, feeding crude propene oxide comprising between 15 and 97% by weight of propene oxide, between 2 and 84% by weight of methanol, and acetaldehyde to a feed point A in the section of the medium of an extractive distillation column; feeding an aqueous solvent of extraction to a feeding point B located above the feeding point A; and by feeding a reactive compound of structure R¹-Y-NH₂, where Y is oxygen or NR² and R¹ and R² are independently from each other hydrogen, an alkyl group or an aryl group, or a salt of said reactive compound, at feed point B , feed point A or between feed points A and B; removing a stream S1 from the top of the extractive distillation column to provide a first propene oxide product containing less than 200 ppm of water; and removing a stream S2 at a removal point 5 to 25 theoretical separation stages above feed point B to provide a second propene oxide product containing between 500 and 10,000 ppm of water.
