Abstract

La presente invención se refiere a un procedimiento para preparar 1,1-dicloro-1-fluoroetano, caracterizado porque comprende los pasos de: a) poner en contacto una mezcla de fase de vapor de 1,1-dicloroetileno y fluoruro de hidrógeno esencialmente anhídro con un catalizador de hidrofluoración para producir una primera corriente de producto que contiene 1,1-dicloro-1-fluoroetano y 1,1-dicloroetileno y, luego b) poner en contacto la primera corriente del producto con fluoruro de hidrógeno anhídro a una temperatura y presión efectivas en donde por lo menos cierta cantidad de la primera corriente del producto está en el estado líquido para formar una segunda corriente del producto, y c) recuperar el 1,1-dicloro-1-fluoroetano con un contenido reducido de 1,1-dicloroetileno a partir de la segunda corriente del producto.
