Abstract

Procedimiento para producir carbamatos fluorados que comprende la reaccion entre una amina o poliamina y un carbonato fluorado, en presencia de catalizadores heterogéneos básicos. El procedimiento también puede comprender una etapa adicional en la que los carbamatos se transforman en los correspondientes isocianatos. Reivindicacion 1: Procedimiento para producir carbamatos fluorados que comprende la reaccion entre una amina o poliamina y un carbonato fluorado de formula (OR)(OR')C=O, en donde R y R' se seleccionan independientemente de un grupo alquilo fluorado C1-20 sustituido o no sustituido, caracterizado porque el procedimiento se realiza en presencia de un catalizador heterogéneo básico seleccionado del grupo que consiste en: un hidroxido doble laminar, un oxido metálico básico, un oxido mixto doble laminar, una zeolita básica, un material mesoporoso básico, un hidroxido de metal alcalino soportado en zeolita, un aluminofosfato amorfo y/o cristalino triturado, o combinaciones de los mismos. Reivindicacion 2: Procedimiento segun la reivindicacion 1, en donde el hidroxido doble laminar tiene la formula general: [MII1-xMIIIx(OH)2]x+(An-)x/n * mH2O donde MII es uno o más cationes metálicos divalentes; MIII es uno o más cationes metálicos trivalentes; A es un anion de carga n-; x varía entre 0,1 y 0,5; n es 1, 2, 3 o 4; y donde el contenido de agua de hidratacion está comprendeido entre 0 y 55% con respecto al peso total del hidroxido doble laminar. Reivindicacion 18: Uso de un catalizador heterogéneo básico seleccionado del grupo que consiste en: un hidroxido doble laminar, un oxido metálico básico, un oxido mixto doble laminar, una zeolita básica, un material mesoporoso básico, un hidroxido de metal alcalino soportado en zeolita, un aluminofosfato amorfo y/o cristalino triturado, o combinaciones de los mismos, para la produccion de carbamatos fluorados.
