Abstract
La presente invencion describe un proceso en fase líquida para producir aductos de alcano halogenados de la formula: CAR1R2CBR3R4 (en donde A, R1, R2, R3 y R4 son como se definio en la especificacion), el cual involucra poner en contacto un alcano halogenado correspondiente, AB, con una olefina correspondiente, CR1R2=CR3R4, en un disolvente de dinitrilo o éster de carbonato cíclico, el cual divide la mezcla de reaccion en dos fases líquidas, y en presencia de un sistema de catalizador que contiene: (i) al menos un catalizador seleccionado de cobre monovalente y divalente; y opcionalmente (ii) un promotor seleccionado de compuestos heterociclicos aromáticos o alifáticos, que contienen al menos un doble enlace carbono-nitrogeno en el anillo heterocíclico. Cuando se forman los hidroclorofluorocarburos, el contenido de cloro puede ser reducido haciendo reaccionar los hidroclorofluorocarburos con HF. Los nuevos compuestos descritos incluyen el CF3F2CCl2CH2CCl3, CF3CCl2CH2CH2Cl, y CF3CCl2CHClF. Estos compuestos son utiles como intermediarios para producir hidrofluorocarburos. También están descritos los azeotropos de CC1F2CH2CF3 con HF, y los azeotropos de CF3CH2CHF2 con HF; como lo están los procesos para producir tales azeotropos. También está descrito un proceso para la purificacion de ciertos hidrofluorocarburos y/o los cloroprecursores de los mismos a partir de mezclas de tales compuestos con HF.
