Abstract

La presente se refiere a un proceso para la hidro-oxidacion de una olefina que tiene tres o m s  tomos de carbono, tal como propileno, para formar un oxido de olefina, tal como oxido de propileno. El proceso incluye poner en contacto la olefina con oxigeno en presencia de hidrogeno y un catalizador de hidro-oxidacion que contiene oro depositado en un soporte que contiene titanio, de preferencia un titanosilicato, y en presencia de un compuesto que contiene halogeno, preferiblemente un haluro promotor tal como un cloruro promotor o una mezcla de un cloruro promotor con uno o m s fluoruros, bromuros y/o yoduros promotores, en donde el promotor comprende un metal del Grupo 1, Grupo 2, de las tierras raras lant nidos o metales act¡nidos de la Tabla Periodica de los Elementos. El compuesto que contiene halogeno mejora la selectividad del catalizador, la eficacia de hidrogeno, y/o la productividad, mientras que a la vez reduce la formacion de agua, la cual se forma como producto concomitante y como subproducto del proceso. Reivindicacion 1: Un proceso de hidro-oxidacion mejorado para la preparacion de un oxido de olefina, que comprende poner en contacto una olefina que tiene tres o m s  tomos de carbono, con ox¡geno en presencia de hidrogeno y en presencia de un catalizador de hidro-oxidacion, que comprende oro depositado en un soporte que contiene titanio, en donde el oro se suministra al catalizador en forma de una fuente de oro, y el contacto se lleva a cabo bajo condiciones de proceso suficientes para producir el correspondiente oxido de olefina; en donde la mejor¡a comprende llevar a cabo el proceso en presencia de un compuesto que contiene halogeno, de tal modo que el proceso emplea una relacion atomica de halogeno con respecto al oro mayor que la relacion atomica de halogeno con respecto al oro correspondiente de la fuente de oro; y a condicion de que cuando haya presente cesio o paladio en el catalizador con un compuesto que contiene cloro o cloruro, entonces el catalizador comprende cuando menos un halogeno adicional diferente de cloro. Reivindicacion 16: Un catalizador que comprende oro y cuando menos un compuesto que contiene halogeno depositado sobre un soporte que contiene titanio, en donde el oro se suministra al catalizador a partir de una fuente de oro, de tal modo que el catalizador tiene una relacion atomica de halogeno con respecto al oro mayor que la correspondiente relacion atomica de halogeno con respecto al oro de la fuente de oro; y a condicion de que cuando hay presente cesio o paladio en el catalizador con cloruro o un compuesto que contiene cloro, entonces el catalizador comprende cuando menos un halogeno adicional diferente de cloro.This refers to a process for the hydro-oxidation of an olefin having three or more carbon atoms, such as propylene, to form an olefin oxide, such as propylene oxide. The process includes contacting the olefin with oxygen in the presence of hydrogen and a hydro-oxidation catalyst containing gold deposited on a support containing titanium, preferably a titanosilicate, and in the presence of a halogen-containing compound, preferably a halide promoter such as a promoter chloride or a mixture of a promoter chloride with one or more fluorides, bromides and / or promoter iodides, wherein the promoter comprises a Group 1 metal, Group 2, of the rare earths nests or active metals. nests of the Periodic Table of the Elements. The halogen-containing compound improves catalyst selectivity, hydrogen efficiency, and / or productivity, while reducing water formation, which is formed as a concomitant product and as a byproduct of the process. Claim 1: An improved hydro-oxidation process for the preparation of an olefin oxide, comprising contacting an olefin having three or more carbon atoms, with oxygen in the presence of hydrogen and in the presence of a catalyst of hydro-oxidation, which comprises gold deposited in a support containing titanium, where gold is supplied to the catalyst in the form of a gold source, and the contact is carried out under sufficient process conditions to produce the corresponding olefin oxide ; wherein the best comprises carrying out the process in the presence of a halogen-containing compound, such that the process employs an atomic ratio of halogen with respect to gold greater than the atomic ratio of halogen with respect to the corresponding gold of the source of gold; and provided that when cesium or palladium is present in the catalyst with a compound containing chlorine or chloride, then the catalyst comprises at least one additional halogen other than chlorine. Claim 16: A catalyst comprising gold and at least one halogen-containing compound deposited on a titanium-containing support, wherein gold is supplied to the catalyst from a gold source, such that the catalyst has an atomic ratio halogen with respect to gold greater than the corresponding atomic ratio of halogen with respect to gold from the gold source; and provided that when cesium or palladium is present in the catalyst with chloride or a chlorine-containing compound, then the catalyst comprises at least one additional halogen other than chlorine.
