Abstract
La presente invención se refiere a un procedimiento para la preparación de alcanos fluorados, caracterizado porque se pone en contacto, a una temperatura de aproximadamente 0 grados C a aproximadamente 185 grados C, bajo condiciones esencialmente anhidras, un equivalente molar de un material de partida que se selecciona de los alcanos halogenados de las siguientes fórmulas R1R2R3R4 C y R5R6R7R8 C en donde r], R2, R3, R4 son CxZ2X+1, en donde Z es H, F, Br, o C1 y x de 0 a 10, con la condición de que por lo menos uno de R1, R2, R3 o R4 sea C1 o Br o contenga C1 o Br; R5 y R6 tomados juntos son -(CH2)n- en donde n es un etnero de 2 a 7, en donde R7 y R8 son CxZ2x+1, en donde Z es H, F, Br, o C1 y x de 0 a 10, con la condición de que por lomenos R7 o R8 es C1 o Br, o contiene C1 o Br, con HF en prsencia de por lo menos un catalizador que se selecciona de pentacloruro de tántalo y pentabromuro de tántalo, a fin de producir un alcano fluorado.
