Abstract

Esta invencion se relaciona con un proceso para producir 1,1,1,2-tetrafluoroetano (HFC-1344). El proceso hace reaccionar el 1,1,1-trifluoro-2-cloroetano (HFC-133a) y el fluoruro de hidrogeno, en un primer reactor. El producto resultante del primer pase de reaccion lleva un segundo reactor junto con el tricloroetileno y el fluoruro de hidrogeno. La segunda reaccion se lleva a cabo a una temperatura más elevada que el primer reactor. Opcionalmente, se remueve el HC1 antes de la remocion del producto crudo de HFC-134a. El HCFC-133a sin reaccionar, el tricloroetileno y el fluoruro de hidrogeno pueden hacerse reciclar de nuevo al primer reactor.
