Abstract
Procedimiento para la obtención de uretanos, caracterizado porque se hacen reaccionar compuestos nitro orgánicos con monóxido de carbono y compuestos orgánicos, conteniendo como mínimo un grupo hidroxi, en fase líquida a temperatura más alta y presión más elevaa, en presencia de paladio y/o compuestos de paladio y de un co-catalizador compuesto tanto de (i) óxidos de hierro y/o hidratos de óxido de hierro, así como también de (ii) compuestos conteniendo cloro aniónicamente ligado como cloruro de los elementos del tercero hasta quinto grupo principal o del primero hasta octavo grupo secundario del sistema periódico de los elementos, con excepción del oxicloruro de hierro y cloruro de paladio y/o cloruros ter.amónicos.
